HSNP74 – HSNP85 SERIES

Etalase : BITZER SCREW COMPRESSORS SEMI HERMETIC

The HS series is the semi-hermetic screw compressor series with built-in motor for use in large commercial refrigeration and process cooling. The HS series is well known for its proven robustness as well as outstanding energy efficiency in full and part load. The HSNP series is especially designed for use with the natural, low-GWP hydrocarbon refrigerants propene (R1270) and propane (R290) to take advantage of the outstanding properties of these refrigerants, especially in medium and low temperature applications. The HSNP series differs from the standard HS series in terms of electronic equipment, safety features and the oil used. As hydrocarbon refrigerants are flammable and are classified as safety class A3, the HSNP series is only available for OEM system suppliers who are experienced in the handling of flammable refrigerants.
