Air-cooled screw refrigerator
Air-cooled screw refrigerator

Product Name: Air-cooled screw refrigerator

Product Details

Air-cooled screw chiller, industrial air-cooled screw chiller
The internationally renowned screw press is used, and high-quality and high-efficiency copper tubes are used to produce condensers, evaporators, and world famous control components. This makes the unit have the advantages of small size, high noise, high energy, long service life, and simple operation.
Features of the press
The internationally renowned brand, a new type of high-efficiency spiral rotor compressor, has a 20% - 30% higher energy efficiency than ordinary compressors, and has obtained patents from European and American countries and ISO9001 international quality certification.
High efficiency 5:6 patented asymmetric rotor gear.
Container control can adopt 4-stage (100% - 75% - 50% - 25%) or 3-stage (100% - 66% - 33%) and stepless control systems
The combination design of 11 bearings and A-type axial thrust balancing drum greatly improves the bearing life by 2.5-3.5 times.
The special groove design of high efficiency silicon steel sheet and equipped with internal and external omnidirectional cooling channels enable the press motor to achieve maximum efficiency under any load.
A unique built-in oil pressure system ensures that the compressor maintains optimal lubrication without the need for an oil pump. The oil separator adopts a double layer filtration method, providing excellent oil filtering effect, and the heat exchanger can maximize energy efficiency.
High efficiency, low noise, low vibration.
A comprehensive selection of press volume ratios (vl=2.2/2.6/3.0/3.5) can effectively avoid additional energy consumption caused by overcompression or insufficient compression.
