OS.A series

With the open drive design, the add-on motor and refrigerant circuit are separate. The OS.A series open drive screw compressors are designed for use in industrial ammonia applications. The series combines high refrigerating capacity with proven reliability and outstanding energy efficiency at full and part load. The integrated capacity control is multistep and, from OS.A85, optionally stepless. All OS.A compressors are suitable for operation with a frequency inverter.

The main features of the OS.A105 compressors are the higher refrigerating capacity, the versatile application range from low temperature to medium temperature applications, and the optimised energy efficiency. This enables BITZER to set new standards in terms of performance and efficiency.
