AMMONIA COMPRESSOR PACKS

Whether for medium or low temperature applications, air conditioning or booster applications, BITZER Ammonia Compressor Packs (ACPs) are just as flexible as the requirements in industrial refrigeration are different. They are available with a wide variety of options and accessories. Always on board: the natural refrigerant ammonia (NH₃, R717).

Refrigerants

  • Ammonia (NH₃, R717)

Capacity range

  • Two series:
    • ACP.85: compressor packs with two or three OS.A85 screw compressors
    • ACP.95: compressor packs with one, two or three OS.A95 screw compressors

Applications

  • High temperature/AC
  • Medium temperature
  • Low temperature
  • Booster

Industry sectors

  • Dairy and process
  • Food and beverage
  • Cold storage
  • Deep freezing
  • Leisure
  • And many more
