OS Series Screw Compressors for HFCs/HFOs

With the open drive design, the add-on motor and refrigerant circuit are separate. The open drive screw compressors of the OS series can be used for numerous application ranges and refrigerants. They combine high refrigerating capacity with proven reliability and energy efficiency at full load and part load. 

The integrated capacity control is multistep and, from OS.85 onwards, optionally stepless. 

All compressors of the OS series are suitable for operation with a frequency inverter.
