ET 500 Two-Stage Piston Compressor Show data sheet (pdf file) Print page
Technical Description

  The trainer provides all necessary data for recording the compressor characteristic and to depict the compression process on a p-V diagram.

  The pressures and temperatures for both stages are recorded using sensors and indicated on digital displays. The air throughput and the electrical power consumption are also measured. The measured values can be read on digital displays. At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition software is included.

  The trainer is equipped with safety devices such as pressure relief valves and pressure switches.
