Two Stage Air Compressor | ThermoFlux - 7092
Product Overview
The Two Stage Air Compressor ThermoFlux - 7092 is a laboratory trainer for studying the operating characteristics and thermal behaviour of a two-stage reciprocating compressor with V-cylinder arrangement. The unit features a water-cooled intercooler between compression stages, a 200 L pressure vessel (8 bar operating, 12 bar maximum), an orifice-type intake flowmeter, and seven temperature sensors covering -100 to 400°C across both stages. This two stage air compressor operates at 2.2 kW, 0 to 900 rpm, and 200 L/min intake capacity, with pressure measurement ranges of 0 to 4 bar and 0 to 16 bar displayed on digital and analogue indicators. Optional LabVIEW-based DAQ software enables p-V diagram representation and PC-based data acquisition via USB.

Construction and Design
The Two Stage Air Compressor ThermoFlux - 7092 is built around a two-cylinder V-arrangement reciprocating compressor rated at 2.2 kW with a variable speed of 0 to 900 rpm. Air enters from atmosphere into an intake vessel that stabilizes incoming pressure. An orifice-type flowmeter, pressure sensor, digital temperature gauge, and analogue pressure gauge are fitted at the intake vessel. After the first compression stage, air passes through a water-cooled intercooler, which controls temperature and stabilizes pressure before the second stage. The second stage delivers compressed air to a 200 L pressure vessel rated at 8 bar operating pressure and 12 bar maximum, equipped with a safety valve, control valve, and outlet silencer.
Seven temperature sensors covering -100 to 400°C, pressure sensors across ranges of 0 to 4 bar and 0 to 16 bar, a differential pressure sensor (-0.5 to 3 in WC), and a power sensor (0 to 5000 W) instrument both stages of this two stage air compressor. All measured values are shown on digital displays. Analogue pressure gauges provide additional direct visual indication. Safety devices including pressure relief valves and pressure switches are installed throughout. Measured values can be transmitted to a PC via USB port when the optional DAQ software is used.

Frequently Asked Questions
Q1: What type of compressor is used in the Two Stage Air Compressor ThermoFlux - 7092?
The unit uses a two-stage reciprocating compressor with two cylinders in a V-arrangement, rated at 2.2 kW with a variable speed of 0 to 900 rpm and an intake capacity of 200 L/min.
Q2: What is the purpose of the water-cooled intercooler in this two stage air compressor?
The water-cooled intercooler is positioned between the first and second compression stages. It controls the air temperature and stabilizes pressure before the air enters the second stage, enabling the study of thermal effects during multi-stage compression.
Q3: What are the pressure and capacity ratings of the storage pressure vessel?
The pressure vessel has a capacity of 200 L, an operating pressure of 8 bar, and a maximum pressure of 12 bar. It is fitted with a safety valve, control valve, and outlet silencer.
Q4: What safety devices are fitted to the trainer?
The trainer is equipped with pressure relief valves and pressure switches throughout to protect against over-pressure conditions.
Q5: Is the p-V diagram functionality included as standard?
No. Recording and representing the compression process on a p-V diagram requires the optional ThermoFlux - 7092 DAQ software, which connects to a PC via USB port and runs in a LabVIEW environment on any Windows operating system.
