Features:
1. The compressor adopts an international brand, a new type of high-efficiency helical rotor compressor, which is 20%-30% more efficient than ordinary compressors, and has obtained IS9001 international quality certification for European and American patents.
2. High efficiency 5:6 patented asymmetric rotor tooth profile.
3. Capacity control can adopt four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and non-stage control system.
4. The combined design of 11 bearings and a-type axial thrust balance drum is adopted, which greatly increases the bearing life by 2.5-3.5 times.
5. The special groove design of high-efficiency silicon steel sheet is adopted, and it is equipped with internal and external omnidirectional design cooling channels, so that the compressor motor can exert the highest efficiency under any load.
6. The unique built-in oil pressure system ensures that the compressor maintains the best lubrication effect without an oil pump. The oil separator adopts a double-layer filtration method, which has a good oil filtration effect and the heat exchanger can exert its maximum capacity.
7. High efficiency, low noise and low vibration.
8. A variety of refrigerants are available. In addition to R22 refrigerant, you can also choose R134a, R407c and other environmentally friendly refrigerants.
9. A full range of compressor volume ratios (VI=2.2/2.6/3.0/3.5) are available for selection. It can effectively avoid extra energy consumption caused by over-compression or under-compression.
