Commercial Refrigeration Training Unit | PolarX – 604
The Commercial Refrigeration Training Unit PolarX – 604 features an air-cooled condensing unit with a hermetic compressor rated for high back pressure and high starting torque. This Commercial Refrigeration Training Unit includes a forced air evaporator with 5 FPI aluminium fins, a detachable insulated hood (100-watt heat load) for thermal performance testing, and an internally equalized thermostatic expansion valve. Pressure monitoring is handled by high and low pressure switches and gauges, alongside 4 Type-k temperature sensors. Optional LABVIEW-based DAQ software supports automated data measurement.
The Commercial Refrigeration Training Unit PolarX – 604 consists of an air-cooled condensing unit with a hermetic compressor featuring high back pressure and high starting torque. This Commercial Refrigeration Training Unit is complete with suction and discharge service valves, gauge manifold connections, and an integrated motor protector.
Product Overview The forced air, blow through, powder-coated evaporator has a detachable front panel and a galvanized sheet steel case. The evaporator is a finned coil type with five fins per inch. The device contains a digital thermometer and can be thermally loaded to investigate performance. Additional components include a thermostatic expansion valve with internal equalization, a liquid line filter drier, a liquid-vapour heat exchanger, high and low pressure switches, a high pressure gauge, and a low pressure compound gauge.
The base of this Commercial Refrigeration Training Unit is made of stainless steel and is set on a steel frame. The forced air, blow through type evaporator includes a 15-watt fan motor. The powder coated galvanized sheet steel casing has a removable front panel. The evaporator coil is constructed from internally grooved copper tube and fitted with aluminium fins at 5 FPI. A detachable insulated hood provides a heat load of 100 watts, monitored by a K type thermocouple.

Construction and Design
The Commercial Refrigeration Training Unit PolarX – 604 uses an air-cooled condensing unit built around a hermetic compressor with high back pressure and high starting torque. The unit includes suction and discharge service valves, gauge manifold connections, and a built-in motor protector. The forced air, blow through evaporator features a powder coated galvanized sheet steel casing with a removable front panel, and its coil is constructed from internally grooved copper tube fitted with aluminium fins at 5 FPI. A detachable insulated hood applies a 100-watt heat load, monitored by a K type thermocouple. The system includes an internally equalized thermostatic expansion valve, liquid line filter drier, and liquid-vapour heat exchanger. High and low pressure switches, along with a high pressure gauge and low pressure compound gauge, provide pressure monitoring. The base is stainless steel, mounted on a steel frame.
Software
PolarX – 604 (optional). A DAQ software package, specially designed in National Instruments LABVIEW environment, measures and calculates the results of the apparatus. The software is optional. When the software is used, a set of electronic sensors is included. The software can be run on any Windows environment.
