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 tubes to make condensers, 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 screw rotary sub-compressor, which is 20%-30% more efficient than a general compressor, 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.
    ◆Using 11 bearings and a-type axial thrust balance rein combination design, greatly increasing 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.
    ◆Unique built-in oil pressure system, no oil pump is needed, and the compressor maintains the best lubrication effect. The oil separation adopts double-layer filtering method, which has good oil filtering effect and the heat exchanger can exert its maximum capacity.
    ◆High efficiency, low noise and low vibration.
    ◆A variety of refrigerants are available. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c can also be used.
    ◆Comprehensive compressor capacity ratio (VI=2.2/2.6/3.0/3.5) is available for selection, which can effectively avoid additional energy consumption caused by over-compressor or insufficient compressor.
