Screw Style Chiller
About Screw Type Water cooled Chiller
The screw type water-cooled chiller adopts a screw compressor as the core component, which generates cooling capacity by compressing refrigerant. At the same time, the device uses water as a cooling medium to dissipate heat to the external environment through a cooling tower or heat exchanger, thereby achieving a refrigeration cycle. Screw type water-cooled chillers have the advantages of compact structure, smooth operation, large cooling capacity, and high energy efficiency, and are widely used in industrial cooling, commercial refrigeration, central air conditioning, and other fields.
