High-Pressure Compressors

We are using three compressors – two membrane and a hydraulic piston compressor. Those supply our test rigs with etyhlene at presssures up to 3000 bar. Furthermore, there is the possibility to feed liquefied gases with a pump into the third stage of one of the membrane compressors.

  • Type: membrane compressor
  • Outlet pressure: 3000 bar
  • Volume stream (standard volume): 4 m³/h
  • Number of pressure stages: 3
  • Producer: A. Hofer Hochdrucktechnik GmbH
  • Year of manufacture: 1991
  • Type: membrane compressor
  • Outlet pressure: 2000 bar
  • Volume stream (standard volume): 3 m³/h
  • Number of pressure stages: 2
  • Producer: A. Hofer Hochdrucktechnik GmbH
  • Year of manufacture: 1978
  • Type: hydraulic piston compressor
  • Outlet pressure: 3000 bar
  • Volume stream (standard volume): 5,6 m³/h
  • Number of pressure stages: 3
  • Producer: A. Hofer Hochdrucktechnik GmbH
  • Year of manufacture: 2009

There is the possibility to feed liquefied gases with a pump into the third stage of the 3000 bar membrane compressor. With this setup mass flows of up to about 500 g·h-1 are achievable depending on the experimental conditions.
