SRH Serie

The tough brother of the SRM compressor sets the pressure benchmark to 63 bar. Thanks to glide bearings and a 4/6 lobe ratio with stronger rotor diameter this compressor range is perfectly suited to operate Ammonia Heatpumps and CO2 cascade systems with their demanding conditions.

With displacements from 161 to 1409 m3/h these compressors are capable to operate heat pumps dependent on the heat source of more than 3 MW and CO2 low temperature cascade systems of approx. 2 MW.

SRH open-type single-stage high-pressure Screw Compressors include 5 models (SRH 12, 16, 18, 20 and 26) 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.
