Screw Compressors
Semi-hermetic
Semi-hermetic
Efficient, robust, durable: thanks to the HSK/N version, HS semi-hermetic screw compressors are suitable for many application ranges and refrigerants. The internal capacity control is multistep and, from HS.85, stepless as an optional feature. All HS compressors are suitable for speed-controlled operation. From HS.95 with IQ MODULE.

The OS series separates the flanged motor and refrigerant circuit. Thanks to the OSK/N version, these compressors are suitable for many application ranges and refrigerants, with a separate series for operation with ammonia. The internal capacity control is multistep and, from OS.85, stepless as an optional feature. All OS compressors are suitable for speed-controlled operation. From OS.95 with IQ MODULE.

The CSV series is optimised for maximum efficiency in liquid chillers and heat pumps with frequency-controlled capacity adjustment. The internal frequency inverter enables a large spectrum of applications and a broad range of control, which simplifies system integration. The CSV series also accommodates all the IQ functions.

Based on decades of experience, these series are designed for the specific needs of railway air-conditioning systems. Thanks to generously sized roller bearings, the compressors are exceptionally reliable with a long service life. Their large frequency range provides optimal full- and part-load efficiency.
