High pressure

High partial load efficiency

› New vapour injection scroll compressor optimised for low load
• UNIQUE back-pressure control: Pressure port increases pressure below the scroll in
low load operation, preventing refrigerant leak and increasing efficiency pressure
• UNIQUE Injection structure with check valve: Prevents volume backflow during low
load operation typically occuring with standard vapour injection compressors
› Variable Refrigerant Temperature adjusts refrigerant temperature to match the load
Pressure port
Lower pressure

High reliability down to -25°C WB

› Hot gas bypass prevents ice buildup at the bottom
of the heat exchanger
