About product                                                                          

 

 Water cooled screw adopt high reliable screw compressor and new high efficiency heat exchanger,high energy effciency ratio,it greatly reduce the operation cost for user,and play an important role on the environment protection and energy saving.

 

The screw compressor of this unit has high efficiency,low noise,and less wearing parts.Neither the umbalance inertia force of piston compressor,nor surge and low effciency operation under the low load of centrifuge,so the unit can high effeciency and reliability in the wide range of load.
