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.
Intelligent microcomputer controller
