DSG Compressor

Booth #N2510

The DSG compressor has been specifically designed for low pressure refrigerants such as R1234ze with low global warming potential. Applications include chiller systems, with a wide range of compressor capacities available to support unit design requirements. The DSG has been specifically designed for low pressure low global warming potential refrigerants such as R1234ze. These refrigerants would usually require a much larger compressor size to have the same capacity as high pressure (R410A, etc.) refrigerants. As chiller manufacturers will need to transition to lower global warming potential refrigerants <700 GWP they will need to move to medium and low-density refrigerants. The DSG with its same size will enable a smooth transition without a significant increase in physical compressor size. It is qualified for R1234ze which is an excellent replacement for the market that has been dominated by R134a for many years, but will be phased down due to its impact on the environment.

The DSG can also be used with other refrigerants with similar properties, so it offers a great deal of flexibility for manufacturers to choose without requiring a new compressor design. This will also support future refrigerant changes and regulations without requiring significant modifications.
