The water-cooled screw chiller is also a type of chiller. Because its main component uses a screw compressor, the name can be called a water-cooled screw chiller. Its chilled water temperature range is 3 ° C ~ 20 ° C, using semi-closed compressor, 20% -30% higher than the general compressor efficiency, high efficiency, simple maintenance, accurate control of capacity, low noise, ground vibration. Can be widely used in plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, food processing and other industrial refrigeration processes need to use chilled water, or large-scale shopping malls, hotels, factories, hospitals and other central air-conditioning projects need to use refrigeration The area where water is concentrated in cooling.
