Product Description
Ce Screw Type Water Cooled Water Chiller for Air Conditioning Use
 
1.Adapt advanced compressorHanbell, Bitzer, high effiency shell and tube type heat exchanger.
2.Equipped with touch screen PLC controller, schneider electronic components and Emerson throttle device,which have higher COP, steady performance.
3. Most importantly, it can save 10% running cost compared with ordinary water chiller unit.

Features of RUIHAI water chillers:

1.Providing -60-5 degree frozen refrigerant, suitable for different customers and  refrigeration capacity requirements.
2.Intelligent control, adjust compressor output automatically according to the load and keep the unit in highest efficiency at any time.
3.Adopting the latest medium and low temperature semi-hermetic single screw type 
compressor or the most advanced gear ratio is 5:6 imported semi-hermetic twin screw type.
Compressor is equipped with unloading capacity control device, and, multistage or 
infinitude energy regulation is available.
4.Evaporator is using internal thread high efficient copper tube, and, combined with the 
unique structure design has the advantage of super heat exchange, compact structure, reliable oil return, easy to maintain, etc.
5.Shell and tube type condenser is using high efficient copper tubes, with the advantages of high heat transfer efficiency, reliable heat transfer, high performance, washable and 
convenient maintenance.
6.The microcomputer controlling system, with powerful security protection, communication, fault diagnosis, automatically adaptation and other function.
