Flooded Screw Chiller - FWSF

Flooded Screw Chiller - FWSF Reliable

Multi-compressors with multiple refrigerant circuits:No oil management problem.Redundancy design, easy to maintain.Multiple compressors staging achieves better part load performance (Range: 12.5% ~ 100%).

According to ambient temperature and users’ need for

indoor temperature, the chiller can start the Efficiency

Enhancing Control Program automatically, then the COP

will be increased and the running cost will be reduced.
