Outstanding performance with high system energy efficiency – the new screw compressor series from BITZER convinced the specialist jury of the China Refrigeration trade fair. The HS95 compressors received the Innovation Product of the year 2019 award in the HVACR Parts category.

Bitzer has successfully developed its compressors further. The new and bigger models of the tried-and-tested HS screw compressor series offer significant efficiency improvements of motors and mechanics, enabling a better system efficiency in full and part load operations than ever before. The semi-hermetic HS95 screw compressors are designed for a wide application range like refrigeration, air-conditioning, heat pump and marine systems and offer displacements of upto 1,015 m³/h (50 Hz). HS95 screw compressors can be used both in single and parallel compressor systems, meaning upto four compressors can be connected. In parallel compounding, they reach displacements of up to 4,060 m³/h.

The HS95 capacity regulation can be performed both with the stepless mechanical capacity control or with the external frequency inverters. The series is designed for a large number of refrigerants like R22, R507A/R404A, R134a as well as for new refrigerants like R1234yf, R1234ze(E) and low-GWP blends. Users benefit from the integrated BITZER IQ module, which ensures an extended protection concept and an accurately fitting slider control. Further advantages are the robust design, the low sound and vibration levels as well as the simple handling and serviceability.
