  A   screw chiller , also known as a screw compressor chiller, is a type of water chiller utilized for cooling applications in various industries, including injection molding. The semi-hermetic screw compressor is the core components of a screw chiller.  It operates based on the principle of a rotary screw compressor, which is a positive displacement compressor. The screw compressor consists of two interlocking helical rotors that compress the refrigerant gas to raise its pressure and temperature. According to different heat dissipation methods, screw chillers are divided into  air-cooled screw chillers  and water-cooled screw chillers. Under the same cooling capacity requirement, the purchase cost of water-cooled screw chillers is lower than that of air-cooled screw chillers. As far as chiller installation is concerned, air-cooled screw chillers are easier to install. Here are some key features of a screw chiller: Cooling capacity: Screw chillers are available...
