Air-cooled (frequency conversion) screw chiller

The air-cooled screw chiller (single/double series) adopts screw compressors of internationally renowned brands (Taiwan Hanbell, Bitzer), supporting high-quality and high-performance copper pipes to make cold field evaporators and world-renowned brand components to make the unit It has the advantages of small size, low noise, large energy, long life, and easy operation. Its beautiful and exquisite shape design and reliable and stable high-performance quality are outstanding among similar products!

Compressor features:

*The compressor adopts an international brand, a new type of high-efficiency pendulum rotary sub-compressor, which is 20%-30% more efficient than ordinary compressors, and has obtained IS9001 international certification quality with patents from Europe and the United States. *High efficiency 5:6 patented asymmetric rotor tooth profile.

+Capacity control can adopt four-stage (100%-75%-50%-25%) or three-stage (100-66%-33%) and stepless control system: *11 bearings and a-shaft The combined design of the thrust balance drum greatly increases the bearing life by 2.5-3.5 times.

+Using high-efficiency silicon steel sheet special groove design, and equipped with internal and external omnidirectional design cooling flow, so that the compressor motor can play the highest efficiency under any load.

The unique built-in oil pressure system does not require an oil pump and ensures that the compressor maintains the best lubrication effect. The oil separation adopts a double-layer filter method, which has a good oil filtering effect and the heat exchanger can exert its maximum capacity. *High efficiency, low noise, low vibration,

A variety of refrigerants are available, in addition to R22 refrigerant, environmentally friendly refrigerants such as R134a, R407c, etc. can also be used

A full range of compressor capacity ratios (VI=2.2/2.6/3.0/3.5) are available for selection, which can effectively avoid additional energy consumption caused by over-compressor or insufficient compressor.
