CS.65 – CS.95 SERIES

On the notepad

The CS compact screw compressor series can be used in an impressively wide range of applications from air conditioning to process cooling and even industrial heat pumps.
Versatile product executions enable system builders to perfectly match their requirements. The integrated oil separator and built-in suction gas cooled motor simplify the system integration and enable a compact and cost-effective system design.
The CS series is equipped with a mechanical slider for capacity regulation and can alternatively be operated with an external frequency inverter.
