HS Series Screw Compressors for HFCs/HFOs

Efficient, robust, durable: The semi-hermetic screw compressors of the HS series are designed for use in large commercial refrigeration applications and process cooling and are also suitable for marine applications. 

The series is known for its robustness, outstanding energy efficiency at full load and part load, and high versatility in terms of the refrigerants used. The integrated capacity control is multistep and, from HS.85 onwards, optionally stepless. All HS compressors are suitable for operation with a frequency inverter. HS.95 compressors are equipped with an IQ MODULE. 

The HSKB booster design is used in 2-stage compound systems in the low temperature range and is approved for operation in the vacuum range.

The HSE screw expanders are suitable for use in ORC waste heat power plants for electric power generation from industrial waste heat.
