Water-cooled screw chiller is a machine that combines a screw compressor, a water-cooled condenser, an evaporator, a throttle valve (or expansion valve), control systems, and other components. These components work together, through the processes of condensing, compressing, evaporating, and throttling, to effectively achieve the cooling effect.
Volks' water-cooled screw chiller utilizes a specially designed semi-closed double screw compressor. This design significantly enhances the unit's lifespan and improves its stability and reliability. So, the unit can run stably in various complex environments.
