Double Stage Compressors – SRM SERIES

The open-drive SRM screw compressor remains the reliable workhorse for its versatility and robustness. Upgraded by the new i-profile rotors with 5/7 lobes and further improved by extra-strong bearings the SRM Series still is the benchmark of industrial refrigeration.

Double Stage Compressors:

For low temperature applications where no side-load on the high stage is needed, like a dedicated package to a spiral freezer, the double stage SRM compressor offers a high efficient solution with lowest footprint compared to a booster system with two packages.

SRM open-type double-stage Screw Compressors include 4 (SRM 1612, 2016, 2620 and 3426) series totaling 7 models with a displacement of 544 – 5090 m3/h @ 2960 rpm. The application window caters especially for low temperature applications, which traditionally were executed as booster systems. If no side-load for the high stage of the booster is needed, these double-stage compressors offer very compact and efficient solutions.

Whereas all major refrigerants can be used, our compressors are optimized for the natural and environment-friendly refrigerants such as Ammonia R717 and Hydrocarbons like R290, R600 and R1150.

The use of frequency inverters, step-less (10%-100%) mechanical capacity control and adjustable Vi ensure high efficient operation at varying load and temperature profiles, thus guaranteeing high SEER values.

The robust design and high degrees of obliquity >30° to withstand the rolling and pounding sea allow the use in marine applications.
