Air-cooled screw chillers
Product Description
Compressor features>>
◆ the use of international brand compressor, the new sub-efficient rotary screw compressors, compressor performance than the average 20% -30% higher, and European and American multi-national patent quality certification of the IS9001.
◆ High efficiency patented 5:6 asymmetric rotor profile.
◆-style volume control can be four (100% -75% -50% -25%) or three-(100-66% -33%) and Stepless control system.
◆ the use of bearings 11 and a type of axial thrust balance portfolio design, bearing life increased 2.5-3.5 times.
◆ special high-efficiency silicon steel sheet corrugated design, and equipped with omni-directional design both inside and outside the cooling flow to the compressor motor at any load can be played under the maximum efficiency.
◆ unique built-in hydraulic system, there is no need also to ensure that the compressor oil pump to maintain the best lubricating effect of oil separation of double-filtering method The oil filter good results, can play a maximum capacity of heat exchangers.
◆ High efficiency, low noise, low vibration.
◆ to choose from a variety of refrigerants, with the exception of R22 refrigerant, but also can choose to use R134a, R407c refrigerant, such as environmental protection.
◆ a full range of compressor capacity (VI = 2.2/2.6/3.0/3.5) options, which can effectively avoid the compressor or compressors have been caused by less than the additional energy consumption.
