Compressors are selected depending on application and operation. We are also happy to comply with specific customer requests. When it comes to choosing a compressor, the required controllability of the refrigeration system or heat pump is decisive. Our units are equipped with hermetically sealed piston or scroll compressors. Alternatively we deploy inverter compressors with output control or digital scroll compressors. Where particularly high output is required, or customers have expressed a particular preference, we also use semi-hermetically sealed compressors.
