Water Cooled Screw Chiller

Applications:
Water cooled screw chiller adopts screw compressors which have lager power than scroll compressors. The screw compressors are usually applied to in chemical plants, ink print plants, automobile factories, central air conditioning systems or other large industrial refrigeration.

Features:
The complete protection functions ensure the steady work of the screw chiller.

There is no need to take isolation measures because of the quite slight vibration of this cooling unit.

Water cooled screw chillers have independent cooling loops. It will not influence the usage of the whole machine if a single device should be repaired or maintained.

Configurations: (voltages, cutters and assigned functions are marked below)
