Product Overview
When a shaft rotates, transverse vibration is produced in it. If the shaft is out of balance, centrifugal forces are generated and vibration begins. If the rotational speed of the shaft matches its natural oscillation frequency, these vibrations multiply. In heavy machinery, this phenomenon is dangerous and must be controlled.
The apparatus consists of a number of shafts of different lengths and diameters. It also includes a center support for the shaft and an end support. The shaft is coupled with a motor. The motor speed can be varied to inspect vibrations at various speeds.

The unit generates air temperatures as low as -20°C while discharging a hot air stream as hot as 70°C.
Product Overview
Internally referenced as IRC-1903, this vortex tube refrigeration unit is built for applications where simplicity, dependability, and compactness are essential. It contains no moving parts and operates through a high-speed spinning vortex created from compressed air at ambient temperature. The vortex action splits the incoming air stream into two separate outputs: cold and hot.
Cold air is delivered at temperatures as low as -20°C, with a cooling capacity of 75 watts. The hot air stream reaches temperatures as high as 70°C. These performance characteristics make the unit suitable for specialized cooling applications where compactness, dependability, and the absence of moving parts are required.
The Absorption Refrigeration Trainer PolarX – 504 is a laboratory unit designed to demonstrate the fundamental operation of an absorption refrigeration system using an ammonia-water solution as the working medium and hydrogen as an auxiliary gas. This absorption refrigeration trainer includes an evaporator, absorber, boiler with bubble pump, and condenser as its primary components, with an adjustable electric heater at the evaporator as the cooling load and digital displays for temperature and power measurement across the refrigeration circuit.
Product Overview
The Absorption Refrigeration Trainer PolarX – 504 demonstrates the principle that liquids begin to evaporate at low temperatures when pressure is lowered. Ammonia liquid evaporates in the evaporator, removing heat from the surrounding air. The absorber absorbs the ammonia steam in water to reduce the evaporation pressure. The high-concentration ammonia solution is continuously purified to sustain the absorption process. In the boiler, acting as a generator, the high-concentration ammonia solution is heated until the ammonia evaporates again. A bubble pump transports the solution within the circuit. The ammonia steam is then condensed and cooled in the condenser before returning to the evaporator. The low-concentration ammonia solution flows back to the absorber. Hydrogen is used as an auxiliary gas to maintain the pressure differential throughout the system.
The boiler can be heated by an adjustable electric heater (60 to 180 W) or alternatively by an optional gas burner using propane, LPG, or natural gas with a piezoelectric igniter. An adjustable 50 W electric heater at the evaporator serves as the cooling load. Power measurement covers a range of 0 to 200 W. Two digital multifunctional power meters each measure AC voltage (0 to 500 V) and AC current (0 to 40 A). Four K-type temperature sensors with a range of -40 to 400°C measure temperatures digitally across the refrigeration circuit. Digital data is captured and displayed for temperatures in the refrigeration circuit as well as the heating capacity at the boiler and the evaporator. Optional LabVIEW-based DAQ software is available for PC-based data acquisition.

Measured values can be read on digital displays. At the same time, measured values can be transmitted directly to a PC via USB (optional). The software allows the process to be represented in a p-h diagram and displays key characteristic variables of the process, such as compressor pressure ratio and coefficient of performance (optional).
This refrigeration system with open compressor allows detailed investigation of pressure and heat losses, since pressure and temperature measuring points are located at all relevant locations.
Identifying faults in refrigeration systems requires comprehensive knowledge of the design and purpose of individual components. The Refrigeration System (Refrigeration & Freezing Chamber) PolarX – 524 trainer helps build this knowledge. Components of a refrigeration circuit with refrigeration and freezing chambers are arranged clearly in the trainer for structured study.
Product Overview
Valves enable individual or parallel operation of the evaporators in the two chambers. The circuit is equipped with a pressure switch for the delivery and intake side of the compressor. The refrigeration chamber features an evaporation pressure controller, and the effect of this controller on the overall process can be examined.
An inner heat exchanger at the inlet of the two evaporators supercools the refrigerant to increase process efficiency. At the same time, the intake gas is superheated. An electric defrost heater is available to defrost the freezing chamber.
A process schematic on the trainer offers a quick overview, with signal lamps indicating the operating state of selected components. Relevant measured values are captured by sensors and read on digital displays. Optionally, the measured values can also be transmitted directly to a PC via DAQ; the data acquisition software is optional.

The Mechanical Heat Pump PolarX – 540 is an educational apparatus designed to demonstrate the fundamental principles of refrigeration. It illustrates how heat is transferred from a colder object to a hotter object using a standard compressor condenser unit. This Mechanical Heat Pump provides both quantitative and qualitative data that is simple for students to understand.
Product Overview Students use the compact instrumentation on this Mechanical Heat Pump to take measurements and perform calculations. All parts and instruments are fixed on a stable platform, making the unit fully stand-alone. The heat pump comprises a thermostatic expansion valve, a water-cooled plate heat exchanger, a hermetic compressor, and an air-heated evaporator. These components are arranged in the same layout used in many household air-water heat pumps and are visible from the front of the unit.
During operation, slightly superheated R-134a refrigerant vapour enters the compressor from the evaporator, and its pressure increases. The heated vapour then enters the water-cooled condenser. The refrigerant loses heat to the cooling water and condenses into liquid before reaching the expansion valve. As the liquid refrigerant passes through the expansion valve, its pressure drops. This causes the saturation temperature to fall below ambient temperature.
As a result, a temperature difference exists between the refrigerant and the air drawn over the evaporator coils. Heat transfer causes the refrigerant to boil, and it leaves the evaporator as a slightly superheated vapour, ready to return to the compressor.
The water flow rate and the water’s inlet temperature regulate the temperature at which heat is delivered in the condenser. Environmental conditions play a significant role in determining evaporation temperature. Instruments are provided to measure the flow rates of cooling water and refrigerant, the power input to the compressor, and all relevant temperatures.

The Refrigeration System with Two-Stage Compression PolarX – 532 is designed for the generation of particularly low temperatures. This Refrigeration System with Two-Stage Compression links two compressors in series, each operating at a low pressure ratio, to overcome the drop in volumetric efficiency that occurs at high pressure ratios.
Product Overview Large pressure differences between the evaporator and condenser are necessary to reach very low temperatures. Since a compressor’s volumetric efficiency drops sharply at high pressure ratios, this Refrigeration System with Two-Stage Compression uses two compressors linked in series, each with a low pressure ratio. This allows the low pressure stage compressor to be sized more advantageously, since its large specific volume requires higher capacity at lower drive power.
Intercooling between the low pressure and high pressure compressors (LP and HP) further increases compression efficiency by bringing the HP compressor’s outlet temperature down to safe levels. The IRC-1909 equipment employs injection intercooling. The receiver injects a small quantity of liquid refrigerant into the LP compressor’s outlet line. As this liquid refrigerant evaporates, it cools the intake gas for the HP compressor.
An add-on heat exchanger in the injection cooler can increase the super cooling of the liquid refrigerant upstream of the expansion valve. This, in turn, increases the evaporator’s capacity. Valves allow the heat exchanger for refrigerant super cooling or the injection intercooling to be switched off, demonstrating the impact of each on the system.
Sensors record and display all relevant measured values. Simultaneous transmission of measurements to the optional programme enables real-time analysis and representation of the process in the p-h diagram. Two flow meters display the volumetric flow rates for the intercooling and the total volumetric flow rate.

The Buckling of Bars FortiTestX-44 provides a clear and controlled demonstration of elastic buckling in long slender bars subjected to compressive forces along their longitudinal axis. When a critical compressive force is reached, such bars lose stability and deflect laterally without material failure, remaining within the elastic stress zone. The apparatus includes a load mechanism for applying compressive forces to test bars that can be pinned or fixed at both ends depending on the buckling condition under investigation. A force gauge measures the applied compressive force, and a dial gauge records lateral deflection of the bar. Test bars of different materials and cross-sections are supplied: three steel bars (600 x 20 x 4 mm), two aluminium bars (600 x 25 x 6 mm), one aluminium circular bar (600 x 10 mm diameter), and one aluminium bar (600 x 15 x 2 mm). The effect of additional shear forces on buckling behaviour is demonstrated through a separate experiment in which a cable and weight apply a shear force at a joint along the buckling bar. This buckling of bars unit enables calculation of expected buckling forces using Euler’s buckling formula and graphical analysis of deflection against force. All components are organised in a storage system (1170 x 480 x 178 mm) with an approximate total weight of 30 kg. The complete experimental setup is housed in the structures test frame mounting frame.
The Young’s Modulus Apparatus FortiTestX-43 is a wall-mounted experimental unit for investigating the elastic elongation of metal wires under tensile loading. This Young’s modulus apparatus enables determination and verification of the modulus of elasticity for steel, aluminium, brass, and copper wire specimens, with elongation measured by a vernier gauge at 0.02 mm graduation. It covers the relationship between wire elongation, applied load, wire diameter, and material properties within a single compact wall-mounted setup.
Product Overview
The Young’s Modulus Apparatus FortiTestX-43 is fixed to a wall-mounted carrier from which wire specimens are suspended. The bottom ends of the wires are secured using two sliders. A traverse connects the wires at their lower ends and distributes applied load evenly across the specimens. Weights are placed on the traverse to load the wires in direct tension. Wire elongation resulting from the applied tensile force is measured using a moment lever fitted with a vernier gauge, providing a displacement range of 100 mm at 0.02 mm graduation. Wire specimens are available in four materials: steel, aluminium, brass, and copper. Each wire is 1000 mm in length with a diameter ranging from 1 to 2 mm. Experiments investigate elastic elongation as a function of applied load, wire diameter, and material, and enable direct determination and verification of the modulus of elasticity for each material. This Young’s modulus apparatus is suited to undergraduate engineering and materials science laboratory programmes requiring hands-on measurement of fundamental elastic material properties.
The Frame Deflections and Reactions FortiTestX-35 is a structural mechanics laboratory unit for investigating vertical and horizontal reaction forces and sway deflection in portal frames under load. This frame deflections and reactions apparatus includes two aluminium alloy portal frames, one with a uniform cross-section and one with a non-uniform leg, enabling direct comparison of structural behaviour across both configurations. Load cells connected to a Digital Force Display measure support reactions, while a digital deflection indicator records sway at the top of the frame.
Product Overview
The Frame Deflections and Reactions FortiTestX-35 mounts to a test frame and provides a complete experimental platform for studying portal frame behaviour under applied loading. Two rectangular aluminium alloy portal frames are supplied, both nominally 250 mm x 500 mm. One frame has a uniform cross-section throughout, with a 25 mm width and 6 mm breadth. The second frame has a non-uniform section, with one leg reduced to 4 mm breadth, producing a smaller second moment of area on that leg. Students clamp each leg of the portal frame to the test frame supports and apply loads using masses on a hanger at the top of the portal structure. Load cells at the supports connect to a Digital Force Display to measure vertical and horizontal reaction forces. A digital deflection indicator measures sway at the top of the portal frame. Using the measured moments and reactions, students plot bending moment diagrams and compare them against theoretical calculations. Sway direction and its causes are examined and discussed. The experiment is repeated with the second portal frame to compare the effect of the non-uniform section on structural behaviour. This frame deflections and reactions unit is supported by optional LabVIEW-based Software FX-35 for data logging and results processing on any Windows operating system. Virtual experiments within the software simulate hardware testing and extend available test conditions to include larger loads, uniform loads, and different test specimens. An optional Automatic Data Acquisition system enables automated collection and logging of experiment results.
Short Introduction
The Deformation of Frame FortiTestX-42 is a structural mechanics laboratory unit for investigating the deformation behaviour of steel frames under load. This deformation of frame apparatus covers both statically determinate and indeterminate conditions using U-shaped and S-shaped steel frames, with two dial gauges recording deflection at 0.01 mm resolution. It supports application of first-order elasticity theory, the principle of superposition, and the principle of virtual work within a single self-contained setup.
Product Overview
The Deformation of Frame FortiTestX-42 provides a comprehensive experimental platform for studying frame deformation, bending moment characteristics, and support reactions under varied loading conditions. The unit includes two steel frames: a U-shaped frame (600 x 600 mm) representing standard portal construction as found in hall structures, and an S-shaped frame (600 x 600 mm) for demonstrating the applicability of analytical methods to non-standard frame geometries. The U-shaped frame is clamped at one end; the opposite end can be left free for statically determinate analysis or fitted with a roller bearing for statically indeterminate investigation. Two sets of weights with movable hooks apply loads at adjustable positions along the frame. Two dial gauges with a 0 to 20 mm measuring range and 0.01 mm graduation record frame deformations under load. Bending moment characteristics are determined using first-order elasticity theory, the principle of superposition, and the principle of virtual work. The differential equation of the bent line is constructed from these characteristic curves and an integrals chart. Displacements and support forces at the movable bearing are calculated from the bent line and its derivatives. This deformation of frame unit stores all components in an organised storage system within a self-contained experimental frame. Optional frame variants FX-42A, FX-42B, FX-42C, and FX-42D extend the apparatus to portal frames with overhanging ends, redundant square frames, unsymmetrical portals, and square portal frames.
The Heat Exchanger Service Unit ThermoFlux – 7108 is a bench-mounted experimental control unit designed to provide hot and cold water circuits for the investigation and comparison of multiple heat exchanger types under parallel flow and counter flow conditions. This heat exchanger service unit is compatible with up to four interchangeable heat exchanger modules — plate type, concentric tube, shell and tube, and jacketed vessel — enabling systematic study of thermal energy transfer, mean heat transfer coefficients, and temperature curve plotting across different exchanger designs and flow configurations.
Product Overview
The Heat Exchanger Service Unit ThermoFlux – 7108 forms the central control and service element of a modular heat exchanger experimental system. The unit houses a stainless steel hot water tank of 50–60 litre capacity fitted with four electric heating resistances of 1.5 kW each (6 kW total), a PID digital temperature regulator, a K-type thermocouple for water temperature measurement, level switches to prevent dry-running of the heater, a stainless steel cover, and a draining valve. Hot water is circulated through the connected heat exchanger by a 0.75 HP centrifugal pump with a flow range of 0–29 litres per minute. Cold water is supplied from the laboratory mains or an optional chilling unit. Two flow meters — one for hot water and one for cold water — each cover a range of 1 to 7 litres per minute. A control valve regulates cold water flow, and a regulation pressure valve set at 0.6 bar prevents excess pressure in the exchanger. Four flexible connecting tubes allow rapid interchange of heat exchanger modules. The structural frame is constructed from anodised aluminium with an insulated HDF wood panel; all water-contact parts are manufactured from PVC, brass, copper, or stainless steel. A front panel diagram with laser-engraved labelling provides a schematic representation of the real unit layout. Temperature is monitored by one K-type thermocouple dedicated to the temperature controller (−100°C to 400°C) and six additional K-type thermocouples (−100°C to 400°C) distributed across the system. Measured values are displayed on digital indicators on the panel and can simultaneously be transmitted to a PC via USB/Ethernet when the DAQ option is selected. The heat exchanger service unit is designed to work exclusively as the service base; at least one heat exchanger module must be ordered separately to conduct experiments.
The Saturation Pressure ThermoFlux – 7069 is a bench-top laboratory apparatus designed to demonstrate the relationship between saturation pressure and boiling point temperature of water across a range of absolute pressures. Equivalent to a Marcet Boiler, the unit adds a throttling calorimeter and a pipe loop for condensate return, providing a comprehensive introduction to two-phase thermodynamics.
Students can generate saturation curves, compare results against published steam tables, and determine the dryness fraction of wet steam using the integrated throttling calorimeter. All sensors route to a USB port for optional PC data acquisition.
Product Overview
The Saturation Pressure ThermoFlux – 7069 heats pure water to its boiling point using a pair of cartridge heaters with variable power control. A sight glass on the front of the boiler allows direct observation of boiling patterns and continuous monitoring of water level.
Saturated steam leaving the top of the boiler travels around a pipe loop before condensing and returning to the base of the boiler for reheating. The operating range covers 0 to 8 bar gauge. The top limb of the pipe loop carries a K-type thermocouple, a temperature sensor, and an electronic saturation pressure sensor. A filling point at the bottom allows the loop to be filled with pure water.
A vapour offtake with an isolating valve diverts steam through a throttling calorimeter. As steam expands to atmospheric pressure, a second K-type thermocouple measures the post-expansion temperature, enabling calculation of the dryness fraction. A pressure relief valve is set to operate if pressure exceeds the working limit; a Bourdon gauge remains operational when power is disconnected.
All power supplies, signal conditioning, and circuitry are contained in an electrical console with current protection devices and an RCD for operator safety. Sensor readings are displayed on a common digital meter. All signals are routed to a USB port for optional connection to a PC using an optional parallel interface and educational software package.
The Combined Convection and Radiation ThermoFlux – 7073 is a small-scale laboratory accessory designed to introduce students to the principles of combined convection and radiation heat transfer from a horizontal heated cylinder. The unit operates in both free convection and forced convection modes, enabling analysis of the combined effects at varying surface temperatures and air velocities.
Measurement of the cylinder surface temperature and the electrical power supplied allows comparison of combined heat transfer effects with theoretical values. The dominance of convection at lower surface temperatures and the dominance of radiation at higher surface temperatures can be demonstrated directly.
Product Overview
The Combined Convection and Radiation ThermoFlux – 7073 comprises a heated cylinder mounted in a vertical air duct with a centrifugal fan at the base. The fan provides variable air flow over the cylinder, enabling study of free and forced convection conditions. A manually adjustable throttle plate permits the air velocity to be varied. On the computer-controlled unit, the air flow is electronically adjustable over the range 0 to 10 m/s by a variable-speed fan; otherwise it is manually adjustable.
The heated cylinder uses a rod heater rated at 100 W at 24 V DC, with a diameter of 10 mm and a length of 70 to 80 mm. The surface of the cylinder is coated with heat-resistant paint that provides a consistent emissivity close to unity. The mounting arrangement for the cylinder in the duct is designed to minimise loss of heat by conduction to the duct wall. The air blower provides air velocity up to 15 m/s.
A K-type thermocouple attached to the wall of the cylinder at mid position measures the surface temperature under varying operating conditions. A K-type thermocouple in the outlet duct measures the ambient air temperature upstream of the heated cylinder. An air velocity sensor within the fan outlet duct measures the air velocity in the duct. Sensor readings enable determination of combined convection and radiation heat transfer coefficients and comparison with published theoretical values.
All sensor signals are available for optional connection to a PC using an optional DAQ software package developed in the National Instruments LabVIEW environment. A comprehensive instruction manual is included.
The Perfect Gas Law Apparatus ThermoFlux – 7077 is a small-scale bench-top unit designed for experimental investigation of the perfect gas law apparatus principles, covering the first law of thermodynamics and the pressure, volume, and temperature relationships for air. Two transparent vessels connected by a large-bore pipe and valve, together with an integral air pump, enable a range of gas expansion and compression experiments.
Air is used as the test gas. The pump can pressurize one vessel and evacuate the other simultaneously. Additional valves allow the vessels to be operated singly or in combination, including venting to atmosphere and controlled transfer between a pressurized vessel and an evacuated vessel.
Product Overview
The Perfect Gas Law Apparatus ThermoFlux – 7077 consists of two transparent vessels: a large vessel with an approximate volume of 18.5 litres and a smaller vessel with an approximate volume of 10.5 litres. The vessels are connected by a large-bore pipe and valve with an integral air pump. The pump pressurizes one vessel while evacuating the other.
Additional valves provide three operating configurations: vessels in isolation, venting to or from atmosphere, and a combined arrangement where the pressurized vessel vents into the evacuated vessel. This range of configurations enables direct observation of perfect gas law apparatus behaviour including transient pressure and temperature responses.
Fast-response thermocouple sensors are located in each vessel to record air temperatures. Individual pressure transducers record chamber pressures. Two pressure gauges, one per vessel, cover a range of -1 to 4 bar. Two temperature sensors, one per vessel, cover a range of -100 to 400°C. Pressure relief valves prevent over-pressurization in the pressurized vessel. Pressure switches limit operating pressures to safe levels.
The vessels and interconnecting pipework are constructed from impact-resistant plastic. A control box digitally displays air temperatures in both vessels. The unit supports optional continuous PC monitoring of pressure and temperature changes. The air pump is available in manual or optional computer-controlled versions.
The Nozzle Pressure Distribution ThermoFlux – 7103 is a laboratory apparatus for measuring pressure curves in convergent and convergent-divergent (de Laval) nozzles and for studying the actual flow of compressible fluids. The unit demonstrates nozzle pressure distribution across subsonic, supersonic, and shock wave velocity ranges using air as the working fluid.
Three interchangeable brass nozzles are provided: one convergent nozzle and two de Laval nozzles with short and long nozzle extensions. The unit also demonstrates the choking effect, where the mass flow rate ceases to increase upon reaching the critical pressure ratio.
Product Overview
The Nozzle Pressure Distribution ThermoFlux – 7103 uses compressed air as the working compressible fluid. Air flows through a selected nozzle and is accelerated, with the nozzle pressure distribution recorded in the direction of flow over several measuring points. The air pressure upstream and downstream of the nozzle can be independently adjusted.
A compressed air regulator with a control range of 0 to 8.6 bar adjusts the upstream supply pressure. A needle valve on the flow meter adjusts the back pressure downstream of the nozzle. The unit accepts a maximum compressed air supply of 10 bar with an approximate air consumption of 5 g/s.
Three brass nozzles with pressure measurement points are included: one convergent nozzle for subsonic investigations, one de Laval nozzle with a short nozzle extension, and one de Laval nozzle with a long nozzle extension for supersonic and shock wave studies. Instruments include a manometer and a digital temperature display upstream and downstream of the nozzle, as well as a rotameter for flow measurement.
Temperature is measured across the range -100 to 400°C. Pressure is measured at 10 points across the range -1 to 9 bar. Flow rate is measurable up to 25 m³/h. Optional DAQ software in the National Instruments LabVIEW environment enables PC-based data recording, storage, and analysis.
The Thermal Expansion Apparatus ThermoFlux-26 is a precision laboratory instrument for determining the linear thermal expansion of brass, copper, and aluminium as a function of temperature. This thermal expansion apparatus uses a dilatometer method with a digital dial gauge to measure dimensional change in 500 mm expansion rods across three materials. Students investigate the direct relationship between temperature change, material properties, and change in length.
Product Overview
The ThermoFlux-26 is designed for quantitative measurement of linear expansion in metallic rods subjected to controlled temperature variation. Three expansion rods, one each in brass, copper, and aluminium, are each 500 mm in length. Temperature is applied via a heating system with a 2-litre tank capacity and a heating power range of 500 W to 1,000 W. Dimensional change is measured using a digital dial gauge with a range of 0 to 20 mm and a resolution of 0.01 mm, providing precise tracking of rod elongation at each temperature step.
The apparatus supports determination of linear expansion coefficients for each material, investigation of the relationship between change in length and overall rod length, and study of equilibrium spacing and thermal capacity. Results are obtained directly from the dial gauge readings against measured temperature.
An optional DAQ software package, developed in the National Instruments LABVIEW environment, is available for automated data acquisition and analysis. When the software option is selected, a set of electronic sensors is included. The software is compatible with any Windows operating system.
The Thermal Conductivity Apparatus ThermoFlux-25 is a laboratory instrument for measuring heat flow across a consistent 100°C temperature differential through five common building and insulation materials. This thermal conductivity apparatus uses a steam chamber as the hot reservoir and a block of ice as the cold sink, with the rate of ice melt into water serving as the quantifiable measure of heat transfer through each test sample. Students determine thermal conductivity values for Bakelite, wood, aluminium, Sheetrock, and Masonite using identical sample geometry across all tests.
Product Overview
The ThermoFlux-25 operates on a straightforward principle: a test sample is clamped between a steam chamber on one side and a block of ice on the other. The steam chamber maintains a constant temperature, creating a 100°C differential across the sample. Heat flows from the steam, through the test material, and into the ice. The rate of ice melting, collected as water into a glass beaker, provides a direct, measurable indicator of the thermal conductivity of each material.
Five sample materials are supplied: Bakelite, wood, aluminium, Sheetrock, and Masonite. Each sample is 100 x 100 mm in face dimension and 5 mm thick. Wood, Masonite, and Sheetrock samples are covered with a thin aluminium sheet for waterproofing, ensuring effective thermal contact during experiments. The steam reservoir is fabricated from stainless steel with a 2-litre capacity and is positioned high above the lab table to eliminate risk of heat damage to the work surface. Meltwater flows directly into the measuring beaker, keeping the lab table free of spillage.
Two steel ice molds, each with a capacity of 300 to 400 ml, are supplied for preparing ice blocks. A glass beaker of 500 ml capacity collects meltwater for measurement. A measuring scale with a range of 0 to 100 N and a resolution of 0.1 N is included. The complete assembly is mounted on a stand with insulating pads.
An optional small steam generator (ThermoFlux-25) is recommended for operation. Optional DAQ software developed in the National Instruments LABVIEW environment is also available, compatible with any Windows operating system. Electronic sensors are included when the software option is selected.
The Small Steam Generator ThermoFlux-24 is a compact, variable-power laboratory heat reservoir designed to provide continuous steam at a constant temperature. This small steam generator boils 3/4 litre of water in ten minutes and delivers continuous steam output at up to 2.5 kg/h. Dual steam ports, a 1-litre water capacity, and variable power from 0 to 3,000 W make it a practical and flexible steam source for laboratory thermal experiments.
Product Overview
The ThermoFlux-24 is built for reliable, consistent steam supply in laboratory settings. It holds 1 litre of water and heats it using an internal electric heater, eliminating any open flame or exposed coil hazard. Variable power adjustment from 0 to 3,000 W allows the user to control steam flow rate to match experimental requirements. Continuous steam output reaches up to 2.5 kg/h.
Two steam ports allow the unit to supply two laboratory groups simultaneously from a single generator. A rubber stopper provides a tight seal and incorporates a safety pressure release function. A low water warning light alerts the user before the water level becomes critically low. An extra-wide base provides stability and resistance to tipping during operation. An included baster allows safe removal of hot water during experiments.
This small steam generator is suitable as a heat reservoir for use with compatible laboratory apparatus, including the Thermal Conductivity Apparatus ThermoFlux-25.
The Extended Surface Heat Transfer Module ThermoFlux – 7049/4 is a laboratory module for investigating temperature distribution and heat transfer along a cylindrical pin fin under combined free convection and radiation conditions. This extended surface heat transfer module uses a 350 mm brass pin fin with 9 thermocouple positions and a 100 W heater to enable direct measurement and comparison with theoretical fin analysis. Students determine thermal conductivity of the rod material and calculate combined convective and radiative heat transfer from the fin surface.
Product Overview
The ThermoFlux – 7049/4 centres on a cylindrical brass pin fin element, 10 mm in diameter and 350 mm in length, instrumented with 9 thermocouple positions along its length. The fin is heated at its base by a 100 W heater. Temperature readings at each of the 9 positions along the rod allow students to plot the full axial temperature distribution and compare measured profiles directly against theoretical predictions from analytical fin equations.
Extended surfaces, commonly referred to as fins, transfer heat from a body by combining conduction within the solid with convection and radiation from its outer surface to the surrounding environment. Pin fins, characterised by a high length-to-diameter aspect ratio, are widely used in cooling systems for electrical appliances such as computer power supplies and substation transformers, as well as in engine cooling applications. The ThermoFlux – 7049/4 replicates this configuration at laboratory scale for structured experimental analysis.
Three core experiments are supported: measurement of axial temperature distribution with theoretical comparison, determination of thermal conductivity of the brass rod material, and calculation of combined free convection and radiation heat transfer from the extended surface with comparison to theoretical predictions.
The module requires the Heat Transfer Service Unit ThermoFlux – 7049 for operation.
The Radiation Heat Transfer Module ThermoFlux – 7049/3 is a laboratory module for demonstrating and verifying the fundamental laws governing thermal radiation heat transfer. This radiation heat transfer module provides an electrically heated radiant source rated at 300 W with a maximum temperature of approximately 460°C, a set of seven metal specimens across three materials, and an aperture plate assembly for structured experimental investigation. Students verify the inverse square law, Stefan-Boltzmann Law, Kirchhoff’s Law, emissivity, absorptivity, and geometric view factor relationships through direct measurement.
Product Overview
The ThermoFlux – 7049/3 is designed to illustrate how thermal radiation, as a mode of heat transfer distinct from conduction and convection, behaves according to established physical laws. A 300 W electrically heated plate serves as the radiant source, reaching a maximum temperature of approximately 460°C. A radiometer measures radiation intensity at the specimen surface. Seven metal specimens in three materials, stainless steel, aluminium, and copper, each measuring 135 x 145 mm, provide a range of surface finishes and coatings for comparative emissivity and absorptivity measurement.
The specimen set covers bright, matt anodized, nickel-plated, and high-temperature painted surfaces. Stainless steel specimens oxidise over time due to high operating temperatures, providing an additional surface condition for study. Aluminium specimens are supplied in three variants: matt anodized on both sides, painted on both sides with high-temperature paint, and matt anodized with one painted side. Copper specimens are supplied in two variants: nickel-plated and bright, the latter also oxidising over time.
An aperture plate assembly, consisting of two plates with insulation on one side, is used in view factor experiments. The insulated surface faces the heated source during experiments to control radiation geometry. All experiments compare measured results against theoretical predictions from the relevant radiation equations.
The module requires the Heat Transfer Service Unit ThermoFlux – 7049 for operation.

The Joule-Thomson Apparatus ThermoFlux-28 is a laboratory and demonstration unit for the experimental determination of the Joule-Thomson coefficient of real gases, specifically CO2 and N2. This Joule-Thomson apparatus is equipped with a heat exchanger, a plastic-coated glass tube with throttle body, two Pt-100 temperature sensor measurement points, and a copper coil heat exchanger of 37.5 m length across 132 coils. The unit operates in an overpressure range of 0 to 10 bar and functions at room temperature, enabling direct measurement and comparison of real gas expansion behaviour against ideal gas theory.
Product Overview
The ThermoFlux-28 measures the Joule-Thomson coefficient by expanding gas across a frit from the overpressure shown on the manometer to ambient pressure. The heat exchanger reheats the gas that has been cooled at the pressure-reducing valve of the gas pressure cylinder back to ambient temperature, bringing the system to a consistent starting temperature before each expansion measurement. This controlled pre-conditioning ensures repeatable results across successive experiments.
The glass section of the unit is enclosed in a transparent plastic case to protect against glass splinters during operation. The plastic-coated glass tube, 250 mm in length and 46 mm in diameter, houses the throttle body and two Pt-100 temperature measurement points. A frame with a pressure gauge and a spiral of copper capillary tube forms the heat exchanger assembly. The copper coil is 37.5 m in total length across 132 coils. The pressure gauge covers 0 to 10 bar with a graduation of 0.05 bar. The digital temperature measuring instrument displays temperature to 0.1°C resolution in differential measuring mode.
The unit operates in an overpressure range of up to 1 bar in standard use and is fundamentally a room-temperature apparatus. Ten structured experiments cover the Joule-Thomson coefficient for CO2 and N2, real gas behaviour, intrinsic energy, Gay-Lussac theory, the throttling phenomenon, the Van der Waals equation, Van der Waals forces, the inverse Joule-Thomson effect, and inversion temperature.
Optional DAQ software (ThermoFlux-28), developed in the National Instruments LABVIEW environment, is available for automated measurement and calculation, compatible with any Windows operating system. A set of electronic sensors is included when the software option is selected.

This cross flow heat exchanger provides hands-on experimentation with interchangeable heating elements, adjustable airflow, and digital measurement display, making it a precise tool for thermal engineering studies.
Product Overview
The Cross Flow Heat Exchanger ThermoFlux – 7078 consists of a vertical air duct through which air is drawn by a radial fan. Three interchangeable heater elements, a pipe, a pipe bundle, and a finned pipe bundle, dissipate heat directly into the airflow. Each heater element operates at 500W. The heating power is adjustable, and the air flow rate is variable, allowing systematic investigation across different conditions.
Electronic sensors measure temperature, differential pressure, and power. All measured values are displayed digitally on the front-mounted instrumentation unit. Data can also be transferred directly to a PC. The flow rate, Reynolds number, and Nusselt number are calculated from sensor data. The temperature-time relationship and the dependence of the Nusselt number on the Reynolds number can be demonstrated graphically.
The heater insert in the pipe bundle configuration can be repositioned across different pipe rows to investigate the effect of flow arrangement on heat transfer performance.
The Dew Point Hygrometer ThermoFlux – 7089 is a laboratory trainer designed to enable students to measure air humidity using four different instruments simultaneously within a single climatic chamber. This dew point hygrometer supports direct comparison of psychrometric, hygrometric, and capacitive measurement methods, providing a comprehensive platform for humidity measurement studies.
Product Overview
The Dew Point Hygrometer ThermoFlux – 7089 is built around a climatic chamber with a transparent door. The chamber houses four humidity measurement instruments: a hair hygrometer with real hair, a hygrometer with synthetic fiber, a capacitive humidity sensor, and a wet and dry bulb thermocouple. All four instruments can be read and compared simultaneously under identical chamber conditions.
The chamber humidity is actively controlled in both directions. Humidification is achieved via an ultrasonic atomizer rated at 22 W with a low-water cut-off. Dehumidification is performed by a Peltier cooling element with a cooling capacity of 58 W at 50°C ambient temperature and a cooling surface of 1600 mm². A recirculation fan circulates air within the chamber to ensure uniform mixing.
Psychrometers operate on the principle of evaporation cooling, comparing ambient temperature with wet bulb temperature. Hair hygrometers use the property of specific fibers to expand with increasing humidity. The capacitive sensor measures changes in the dielectric constant of a layer caused by absorbed water molecules. All three principles are represented in this trainer, making it suitable for direct instrument comparison and methodology studies.
An optional Whirling Psychrometer (TH-3117-01) with a measuring range of -5 to 50°C and 1°C graduation is available as an accessory. Optional DAQ software is available for PC-based data acquisition.
The Recycle Loops ThermoFlux – 7089 is a bench-top laboratory apparatus designed to demonstrate recycle loop behaviour and enable mass and energy balances under both steady state and unsteady state conditions.

Product Overview
The Recycle Loops ThermoFlux – 7089 consists of a through pipe conveying water from a cold-water supply to a drain, with a loop of pipework connected between the supply and drain connections. The recycle loop incorporates a variable-speed gear circulating pump (12 lpm, 4 bar, 180 W) and a 0 to 3000 W electric heater with over-temperature protection. A pressure regulator with filter at the inlet minimizes the effect of fluctuations in the cold-water supply pressure.
Loop flow rate is variable from 0 to 7 l/min, and the passing flow of water is also variable from 0 to 7 l/min. The heater can be switched on or off to generate step changes for transient response investigation. A waste-free quick disconnection fitting enables a short pipe or a 1 L reservoir to be connected in series with the recycle loop to change the loop volume and demonstrate the effect of residence time. Different lengths of flexible tubing can also be connected in series for further residence time variation.
Water temperatures at the inlet, outlet, and within the recycle loop are measured by K-type thermocouples. Flow rates at the inlet, outlet, and corresponding loop locations are measured by miniature turbine-type flow sensors. Flow sensors at both inlet and outlet demonstrate that these two flow rates remain equal regardless of recycle rate. All power supplies and signal conditioning circuitry are housed inside the control panel. The console includes a digital meter displaying temperatures and flow rates. Signals can be sent to DAQ via LAN or USB port for PC connection. An RCD and appropriate current protection devices are fitted for operator protection.

The nozzles are designed to operate at different theoretical expansion ratios and can be exchanged rapidly.
The unit measures both the reaction force (thrust) of the fluid at the nozzle and the action force at the baffle plate. Force measurement is performed by deformation of a flexion pipe, with a measuring range of 0 to 5 N. The distance between the baffle plate and the nozzle is adjustable. Air intake is adaptable according to the experiment layout. A compressed air regulator with a control range of 0 to 10 bar adjusts the pressure downstream of the nozzle. A needle valve on the flowmeter adjusts the back pressure.
Instrumentation includes a manometer and digital temperature display upstream and downstream of the nozzle, as well as a flowmeter. Measuring ranges cover temperature (-100 to 400°C), pressure (2x 0 to 10 bar), mass flow (0.7 to 8.3 g/s), and force (0 to 5 N). Operating conditions can be varied rapidly to generate results across a wide range of pressure ratios. Optional DAQ software enables PC-based data acquisition in a LabVIEW environment.
Product Overview
The unsteady state heat transfer unit consists of a stainless steel water bath with an integral flow duct and an external water circulating pump. The bath has a capacity of approximately 30 liters.

The Tray Dryer ThermoFlux – 7101 is a laboratory unit designed to investigate and demonstrate the process of convection drying of granular solids using hot air flow through a rectangular drying channel. This tray dryer features four corrosion-resistant removable trays, an adjustable-speed axial fan, a 0 to 3500 W controlled heater, a digital balance, combined humidity and temperature sensors before and after the drying zone, and an air velocity sensor, providing a complete platform for drying curve analysis and energy and mass balance evaluation.
Product Overview
The Tray Dryer ThermoFlux – 7101 consists of a rectangular drying channel approximately 2000 mm in length with internal dimensions of 350 x 350 mm. An axial flow fan at the left end draws air into the duct. Fan speed is adjustable, with a maximum output of 700 m³/h and a maximum speed of 950 min⁻¹, consuming 33 W. A bank of electric heaters downstream of the fan raises the air temperature, with power adjustable from 0 to 3500 W and a temperature limiter included. A transparent door in the drying channel allows the drying process to be observed directly.
Four corrosion-resistant drying trays measuring 300 x 300 mm each are placed in the channel. The trays containing the solid to be dried are exposed to the airflow, which heats the solid and removes released moisture. A rack of trays is suspended from a digital balance above the duct. The balance has a measuring range of 0 to 10,000 g with a resolution of 0.1 g and an application temperature range of 0 to 75°C, enabling continuous monitoring of weight changes due to moisture evaporation.

The unit consists of an insulated stainless steel tank through which exhaust gas flows from bottom to top, transferring its heat to a looped finned pipe heat exchanger carrying cooling water. Four temperature sensors and a flow meter record all relevant parameters; values are displayed digitally via a measuring amplifier.
Product Overview
The Exhaust Gas Calorimeter ThermoFlux – 7105 determines the amount of heat contained in the exhaust gas from test engines. The calorimeter consists of a finned pipe heat exchanger housed in an insulated stainless steel tank. Exhaust gas enters at the bottom of the tank and flows upward, giving up its heat almost completely to cooling water circulating through the finned pipe.
The finned pipe is arranged in loops to maximise the heat exchange area. The heat exchange area on the exhaust gas side is 1.169 m². The heat exchange area on the water side is 0.164 m². This large ratio ensures thorough and near-complete heat transfer from the exhaust gas to the cooling medium, which is the core operating principle of the exhaust gas calorimeter.
Four temperature sensors record exhaust gas inlet and outlet temperatures and water inlet and outlet temperatures. A flow meter records the cooling water flow rate. All measured values are recorded electronically and displayed digitally using a measuring amplifier. The engine is connected to the calorimeter via an exhaust gas hose. The specific heat capacity of the exhaust gas can also be determined from the recorded data.
The Heat Conduction and Convection ThermoFlux – 7106 is a laboratory apparatus designed for basic experiments on heat conduction and convection, two of the three fundamental forms of heat transfer. Six interchangeable metal samples, each functioning as a cooling fin, are heated at one end and dissipate heat through conduction along their length and convection to the surrounding air.
Six fans below the sample provide continuously adjustable forced air flow, enabling comparison between free convection with still air and forced convection with flowing air. The effect of different materials and different sample lengths on heat transfer can be directly compared. Microprocessor-based instrumentation is integrated into the housing; heating power and fan speed are controlled and displayed via software.
Product Overview
The Heat Conduction and Convection ThermoFlux – 7106 centres on six metal samples: two long samples (copper and steel) with a heat-dissipating length of 154 mm and a heat transfer area of 48.4 cm², and four short samples (copper, aluminium, brass, and steel) with a heat-dissipating length of 104 mm and a heat transfer area of 32.6 cm².
Each sample is placed on a heater rated at 30 W with a temperature limit of 160°C. The sample is heated at one end; heat is conducted along its length and dissipated to the environment, replicating the behaviour of a cooling fin. Six fans with a maximum flow rate of 40 m³/h, nominal speed of 14,400 min⁻¹, and a power consumption of 8 W per fan provide adjustable forced air flow around the sample, enabling heat conduction and convection experiments under both free and forced convection conditions.
Eight temperature sensors measure temperatures across the range -100 to 400°C. Flow velocity is measured from 0 to 10 m/s. Heating power is measured and controlled over 0 to 30 W. All measured values, including temperatures, heating power, and air velocity, are displayed in the software. The integrated microprocessor-based instrumentation requires no additional external devices or error-prone wiring. Optional DAQ software in the National Instruments LabVIEW environment enables PC-based data acquisition on any Windows system.

The Film & Dropwise Condensation ThermoFlux – 7097 is a laboratory unit specially designed to enable students to visualise and investigate both filmwise and dropwise condensation processes within a transparent glass test section. This film and dropwise condensation unit includes two water-cooled copper and brass condenser tubes with different surface treatments, a 3 kW controlled heater, a water jet vacuum ejector, six thermocouples, two rotameters, and a pressure gauge for comprehensive condensation heat transfer analysis.
Product Overview
The Film & Dropwise Condensation ThermoFlux – 7097 is built around a transparent glass cylinder test section that allows direct visual observation of the condensation process. Two water-cooled condenser tubes are installed inside the tank: one with a gold-plated surface to realise dropwise condensation and one with a natural finish surface to realise filmwise condensation. Both condensers are fabricated from copper and brass alloys, have a diameter of 15 mm and an effective length of 95 mm, and are each fitted with a thermocouple.
In filmwise condensation, a film of condensate forms and spreads over the wettable natural finish surface, increasing in thickness as vapour continues to condense. This liquid film acts as a poor thermal conductor, contributing to thermal resistance. In dropwise condensation, the non-wettable gold-plated surface causes condensate to form as spherical beads that grow, coalesce, and flow downward, leaving bare surface areas with very low thermal resistance and enabling high heat fluxes.
A 3 kW electric heater with a temperature controller adjusts the boiling temperature within the tank. A water jet vacuum ejector evacuates the tank to enable operation at sub-atmospheric pressures. A pressure switch and safety valve are fitted for safe operation. Six thermocouples with a digital temperature indicator (range: -100 to 400°C) measure temperatures across the system. A pressure gauge with a range of 0 to 6 kg/cm² measures tank pressure. Two rotameters measure the cooling water flow rates for both condensers independently.

This thermoelectric engine is sandwiched between a 100 W electric heater hot source and an air-cooled or water-cooled cold sink, generating current to drive an electric motor with a fan propeller, and measures temperature, voltage, and electrical current with digital displays.
Product Overview
The Thermoelectric Engine ThermoFlux – 7085 operates on the principle of thermocouple technology, where multiple semiconductor thermocouples are mounted on a cell to form a multi-cell thermoelectric generator. The generator is positioned between a hot source and a cold sink. The hot source is provided by a 100 W electric heater integrated into the surface. Alternatively, a spirit lamp or other external heating source can be used. The cold sink is either air-cooled via a fan propeller or water-cooled, selectable at the time of order.
The current generated by the thermoelectric effect drives an electric motor on which the fan propeller is mounted. On open circuit, the generator produces an EMF of a few volts with a maximum current of approximately 1 amp. Generator power output is 5 W. The electrical power supply is freely adjustable via a potentiometer.
Hot and cold surface temperatures are measured using thermocouples with digital display across two channels covering -100 to 400°C. Electrical current and voltage are also measured and displayed digitally. All components are arranged clearly at the front of the experimental unit.
For the water-cooled system, a shared water circuit with a tank, pump, and rotameter flow meters is included for both heating and cooling water flows. The cooling system, air or water, must be selected at the time of order.

It provides a complete experimental platform for studying triaxial stress states as applied to pressure vessel and pipeline design.
Product Overview
The Thick Wall Cylinder FortiTestX-41 addresses the uneven stress distribution across the wall thickness that distinguishes thick-walled pressure vessels from thin-walled ones. Under internal pressure, this thick wall cylinder enters a triaxial stress condition, with radial, circumferential, and axial stresses and strains developing simultaneously. Because internal strains cannot be measured directly, the unit uses surface and groove-mounted strain gauges to estimate the full internal stress and strain state. The apparatus consists of a two-part oil-filled aluminium cylinder sealed hermetically. Internal pressure is generated by a hydraulic cylinder and spindle arrangement, and displayed on a pressure gauge graduated to 100 bar, with a maximum operating pressure of 7 N/mm² (70 bar). An eccentric flat groove is machined between the two cylinder sections, where strain gauges are bonded at various radial positions. Additional strain gauges are placed on both the inner and outer surfaces of the cylinder. Ten strain gauges in total, configured as half-bridges at 350 Ohm with a gauge factor of 2.00 +/- 1%, provide complete documentation of the radial, hoop, and axial strain state. A measuring amplifier with 10 V supply reads the signals directly. Optional Windows-based Software FX-41 loads measured values for visual evaluation and graphical Mohr’s Circle representation of the triaxial stress condition. Elasticity equations are applied to convert measured strains into direct stresses.

A moveable piston controlled by a threaded spindle bolt seals one end of the cylinder, allowing selection between two load conditions: the uniaxial stress state of an open-ended pipe, and the biaxial stress state of a sealed container such as a boiler tank. Internal pressure is generated by a hydraulic hand pump fitted with a factory-preset pressure release valve, and is indicated by a pressure gauge graduated to 30 bar. Oil fills the sealed cylinder interior. Five strain gauges are bonded to the outer surface of this thin wall cylinder in half-bridge configuration at angles of 0°, 30°, 45°, 60°, and 90° to the cylinder axis, covering both hoop and longitudinal stress and strain positions. A universal strain gauge amplifier with a 10 V supply reads measured strains directly.

The ThermoFlux – 7015 Pressure Measurement Bench provides a structured platform for studying pressure and vacuum measurement across a range of instrument types. The manometer panel integrates two tube manometers (U-tube and inclined tube), two dial manometers (positive and negative range Bourdon tube), and one digital pressure transmitter with display — allowing direct comparison of measurement methods under identical test conditions.
Test pressures in the millibar range are generated using the supplied plastic syringe or hand pump. All manometers can be interconnected via flexible connecting hoses, enabling gauge pressure and vacuum measurement configurations. The bench also serves as a calibration training tool: deviations between a measuring instrument and a reference standard are identified, recorded, and corrected.
The integrated Dead Weight Pressure Calibrator provides an introduction to manometer calibration fundamentals. It consists of a precision-machined piston and cylinder assembly mounted on levelling screws. Known dead weights are loaded onto the piston rod, which is rotated during operation to minimise friction. The ratio of applied force to piston cross-sectional area produces a defined, traceable test pressure transferred hydraulically to a Bourdon tube gauge. An error curve is drawn by comparing gauge readings against known applied pressures. Both dial and Bourdon tube manometers can be calibrated using this dead-weight piston method.
Polariscope FortiTestX 19 is a dedicated strength of materials lab equipment unit designed for the investigation and measurement of principal stress components and stress directions in photoelastic specimens using the photoelastic method. This Polariscope apparatus uses circularly polarised light passed through transparent, optically double-refractive plastic models under mechanical loading to produce visible fringe patterns representing stress distribution. The FortiTestX 19 supports white light and monochromatic light operation, accommodates six polycarbonate model types, and applies bending, tensile, and compressive loads via a threaded spindle, making it a complete polariscope strength of materials lab equipment unit for undergraduate stress analysis and experimental mechanics programmes.
Product Overview
The Polariscope FortiTestX 19 is a self-contained strength of materials lab equipment unit for photoelastic stress analysis on flat, transparent plastic models under external mechanical loading. The experimental setup consists of a light source, four filters arranged to produce circularly polarised light, and a frame with height-adjustable cross-arms and load-bearing attachments for the models. The light source provides two operating modes: white light via a fluorescent tube for coloured stress pattern visualisation, and monochromatic yellow light via a sodium vapour lamp for dark and light contrast fringe patterns. Circularly polarised light is produced by passing light through a polarisation filter followed by a quarter wave plate. A second quarter wave plate perpendicular to the first, together with a second polarisation filter acting as an analyser, is positioned behind the model. All four filters are enclosed in glass with a diameter of 425 mm, mounted on roller bearings with 360 degree angle scales and main optical axis markings, and rotate freely for precise angular adjustment. The frame measures 600 x 750 mm with height-adjustable cross-arms. A load application device uses a threaded spindle to apply bending, tensile, or compressive loads to the model under test. Six polycarbonate model types are supplied: arch model, mounting model, crane hook model, weld seam model, notches model, and wrench model. Stress distribution is observed by identifying bright patches and interpreting isochromatic fringe patterns, with dark isochromatics assessed to determine the principal stress difference. Custom models can also be used, providing flexible experimentation configurations beyond the supplied set.

Two support conditions are provided: a built-in support using a cylinder in a socket, and a pivot support using a wedge on a V-notch. An axial bearing between the spindle and the bar support protects the test bar from torsional loading during force application. Force is measured by a hydraulic load cell up to a maximum of 2000 N with 0.1 N graduations, displayed on a pressure gauge. Lateral deflection is measured by a dial gauge with 0.01 mm graduation across a maximum deflection range of 20 mm. A transverse load application mechanism generates additional shear forces on the test bar using a weight hanger and weights up to a maximum of 20 N. The unit operates in both vertical and horizontal orientations, with the load gauge rotatable by 90 degrees to suit the selected orientation. Test bars in aluminium, copper, brass, and steel across lengths up to 700 mm are supplied. A supplementary set extends the column buckling experiment range to include varied cross-sectional shapes, eccentric force application, and additional transverse loading. All components are organised and stored in a dedicated storage system. Optional LabVIEW-based software (FX- 17) enables data logging and results processing on any Windows operating system.
Product Overview
The ThermoFlux – 7027 Free and Forced Convection Heat Exchanger provides a structured experimental platform for studying the fundamental mechanisms of convective heat transfer as applied to industrial heat exchanger design. The apparatus centres on a vertical air duct (120 × 120 mm flow cross-section, 1000 mm height) into which plug-in heated surface modules of known dimensions are presented to the air stream for detailed thermal analysis.
Three standard heating modules are supplied — a finned surface, a pipe bundle, and a flat surface — each rated at 150 W. An axial fan mounted at the top of the duct delivers the controlled air stream for forced convection experiments; free convection studies are conducted with the fan inactive. Each module may also be used independently on the bench in horizontal orientation to establish free convection coefficients outside the duct.
The control panel integrates temperature measurement, continuously variable heating power control (0–100 W output with direct watt readout), and fan speed control. Temperature is measured to a resolution of 0.1°C using thermocouple sensors with direct digital readout in °C. Air velocity is measured using a portable anemometer mounted on the duct. All heating elements are subject to a 90°C temperature limitation.
Optional modules — a plain cylinder, a cylinder with heating foil for local heat transfer investigation, and a plate surface — extend the experimental scope. The optional ThermoFlux – 7027 DAQ software, developed in the National Instruments LabVIEW environment, displays temperatures, heating power, and air velocity, and calculates results automatically.
The ThermoFlux – 7023 Boyle’s Law Apparatus provides a focused experimental platform for investigating the relationship between pressure and volume in a gas maintained at approximately constant temperature. Air is used as the test gas, requiring no specialist gas supply.
The enclosed air volume within the transparent vessel is reduced or increased by a built-in 60 W pump that displaces hydraulic oil into or out of the vessel. When volume changes occur slowly, the process approximates isothermic conditions, satisfying the requirements of the Boyle-Mariotte Law. A 3/2-way valve switches the pump between compression and expansion modes; the same compressor is also operable as a vacuum pump, extending the range of this Boyle’s Law Apparatus into sub-atmospheric pressures. Pressure is monitored via a gauge over a 0–4 bar range; volume varies over approximately 0–1.5 L; and temperature is measured electronically over –100°C to 400°C. The transparent vessel construction allows direct visual observation of the change of state throughout each experiment.
The Changes of States of Gases ThermoFlux – 7019 is a dedicated laboratory apparatus enabling students to study and experimentally verify two fundamental gas laws: the isothermic change of state (Boyle-Mariotte Law) and the isochoric change of state (Gay-Lussac’s Law). This Changes of States of Gases unit uses air as the test gas across two independent transparent vessels, each instrumented with pressure and temperature sensors for direct, quantitative observation.
The ThermoFlux – 7019 Changes of States of Gases apparatus provides a structured experimental platform for investigating thermodynamic gas behaviour under controlled conditions. The unit is divided into two functional vessels, each dedicated to a distinct gas law, operated independently or comparatively.
Vessel 1 (Isothermic — Boyle-Mariotte Law): Positioned on the left, this transparent vessel encloses a variable air volume. A built-in pump displaces hydraulic oil to reduce or increase the enclosed air volume, producing a controlled isothermic change of state. A 3/2-way valve switches between compression and expansion modes; the pump can also function as a vacuum pump. When changes occur slowly, temperature remains approximately constant, satisfying isothermic conditions. Pressure is measured over a gauge range of 0–4 bar; volume varies over approximately 0–3 L.
Vessel 2 (Isochoric — Gay-Lussac’s Law): Positioned on the right, this transparent vessel encloses a fixed volume of air. A controlled electric heater raises the gas temperature; the resulting pressure rise is measured at constant volume, demonstrating Gay-Lussac’s Law directly. Temperature and pressure are measured electronically via integrated sensors.
Both vessels share a pressure measuring range of 0–4 bar gauge and a temperature measuring range of –100°C to 400°C.
