Product Advantages
1.AHRI Certified
2.Cutting-edge Screw Compressor Technology The product adopts a semi-hermetic twin-rotor screw compressor,a screw rotor using a patented profle undergoing the optimized compression process with a German KAPP gear grinding machine,and the surface has been laser-hardened to implement dynamic and static balance correction. The twinscrew rotors adopt the asymmetric patent design of five to six tth,reaching the machining precisin of micron level and ensuing low noise and long service life. The compressor adopts the bearing o iteternational famous brand SKF,which has a long service life,ensuring that the continuous operation time of the ciller is at least 5000h.
3.Full Flling Fim Evaporation Technology First created full flling flm evaporator reduces the rfrigerant charge amount. Spray flling flm technology llowus the rfrigrant to form a lquld fim on the surface of the eficient heat exchange tube to implement flm state evaporation and greatly improve the heat exchange eficiency of the evaporator. The rfrigerant dsributor is speciallyl designed to avoid uneven liquld distribution and prevent local pipe dryness. (Patent No:2011201344215)
4.Stepless Capacity Adjust The capacity adjust system consists of the capacity adjust slide valve, solenoid valve and oil pressure piston.
