A water-cooled screw chiller is a type of refrigeration equipment that is used to maintain the temperature of water in a large-scale industrial process or building.
In general, a screw chiller works by compressing a refrigerant gas such as R22 or R410A, which then transfers the heat absorbed from the process or building to a cooling tower for dissipation. The screw refers to the type of compressor that uses two interlocking helical rotors to compress the refrigerant gas.

Product Description
A water-cooled screw chiller differs from an air-cooled chiller in that the former uses a cooling tower and water circulation system to dissipate heat, while the latter uses outdoor air to remove heat through an air-cooled condenser.
Water-cooled screw chillers are commonly used in large commercial and industrial applications such as plastic manufacturing plants. They are known for their energy efficiency, quiet operation, and reliable performance.
