Features
1.World famous brand new type and high-efficient screw-rotor compressor, with efficiency 20%~30% higher than those common ones. It has obtained several patents of Europe and America countries and passed the international quality certification of ISO9001.
2.High efficiency 5-to-6 rotor profile patent.
3.Capacity control apply to four-step (100%-75%-50%-25%),three-step (100%-66%-33%) and no step control system.
4.With 11 bearings and a balance piston against axial thrust. This extends longer bearings life 2.5 to 3.5 times than traditional design.
5.Designed with efficient silicon steel and special slots , and equipped with the inside and outside all around design to cool the flow channel so to ensure maximum efficiency of the compressor motor under any load.
6.Built-in oil pressing system ensure compressor maintaining the optimal lubricity without oil pump.
7.High efficiency double filtration oil separator ensures maxinum heat exchanger.
8.Efficient, low noise and small vibration.
9.Various options of refrigerants, R22, environment-friendly R134A, R407C etc.
10.All-wave compressor volume ratio(Vi=2.2/2.6/3.0/3.5) for selection to avoid the extra energy consumption caused by over or under compression.

Water side of the evaporator and condenser, designed to withstand a pressure of 1.0MPa; 7. The actual head of Host is that the pump head minus head losses within the host; 8.In addition to the specifications and requirements, We can provide non-standard products according to customer requirements.

Application:
Our water cooled screw chillers, water cooled screw type low temperature unit, flooded type water hillers, air-cooled screw chiller, air-cooled, water-cooled box type chillers products have been widely used in chemical industry, chemical fiber, plastics, oil, food, as long as the industry, printing, electroplating, electronics and other industries

Recommend products:
Usually cooling tower offers chilled water to water cooled chiller, here we recommend our dry cooler to instead of cooling tower.
