Product Details

Using internationally renowned screw compressors, equipped with high-quality high-performance copper tubes to produce condensers, evaporators, and world famous control components, the unit has the advantages of small size, low noise, large energy, long life, and easy operation. Its beautiful and exquisite appearance design and reliable and stable high-performance quality are outstanding among similar products!
Features of screw chiller compressor:
◆ The compressor adopts an international brand, a new type of high-efficiency spiral rotor compressor, which has a 20% - 30% higher efficiency than ordinary compressors, and has obtained international quality certification from European and American patents and is9001 international quality certification.
◆ 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.
◆ The combination design of 11 bearings and a type axial thrust balancing drum greatly improves the bearing life by 2.5-3.5 times.
◆ Adopt a special groove design of high efficiency silicon steel sheet, and equipped with internal and external omnidirectional cooling flow channels, enabling the compressor motor to achieve maximum efficiency under any load.
◆ A unique built-in oil pressure system ensures that the compressor maintains optimal lubrication without oil pumps. The oil separator adopts a double layer filtering method, providing excellent oil filtering effect, and the heat exchanger can maximize its capacity.
◆ High efficiency, low noise, and low vibration.
◆ Various refrigerants can be selected. In addition to R22 refrigerant, environmental friendly refrigerants such as R134a and R407c can also be selected.
◆ A comprehensive selection of compressor volume ratios (vi=2.2/2.6/3.0/3.5) can effectively avoid additional energy consumption caused by overcompression or insufficient compression.
