SRH-20

Open-type Single-stage High-pressure Screw Compressor

SRH open-type single-stage high-pressure Screw Compressors include 5 models with a displacement of  161- 1409 m3/h @ 2960 rpm. The large application window is optimized for two applications:

  • CO2 Cascade Systems
  • Ammonia Heatpumps


Rotor speed of up to 3600 rpm allow the use of frequency inverters. Togheter with step-less (10%-100%) mechanical capacity control and adjustable Vi this ensures high efficient operation and adaptation to varying load and temperature sources, thus guaranteeing high SEER values.
