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.
