MG air cooled screw chiller widely used in plastic injection, extrusion, plating, mold, hydraulic, chemical, leather, printing, profiles of oxidation, reaction kettle, chemical fiber, vacuum coating, paper making, textile, central air conditioning refrigeration and various aspects of water centralized water supply, especially suitable for the inconvenience for water and the water pipe ground.

As a leading air cooled screw chiller supplier, MGREENBELT Chiller provides a complete range of air-cooled screw chiller from MG-CS series, with cooling capacity from 50Ton to 580Ton/130KW to 1950KW and the chiller temperature control range is +30℃ to -30℃.

Besides the standard air-cooled screw chiller control temperature of 7℃ to 30℃, TopChiller also has air-cooled glycol screw chiller control temperature below zero from 0℃ to -30℃

Each air cooled screw chiller designed from MG Chiller has the following features:

Using world famous brand semi-hermetic screw compressor- Bitzer from Germany and Handbell from Taiwan.

Each screw compressor with 4 steps of energy control 25%-50%-75%-100% to make sure the whole screw chiller is stable and guarantee high refrigeration performance. There are also 2 or 3 compressors for optional depends on the required refrigeration capacity.

Highly efficient closed loop shell and tube type heat exchanger as the evaporator, and using air cooled type condenser-Copper tube sleeve aluminum fin with big volume air cooling fan.

Integrated PLC control system with human-computer interface and big LED touch screen panel for easy operation and troubleshooting.

World famous refrigeration spare parts like Danfoss brand thermal expansion valve, Alco dryer filter, Schneider electrical contactor, and overload relay will make sure the whole air cooled screw chiller works under normal conditions.

The above original quality refrigeration spare parts will ensure each air cooled screw chiller at a steady running condition.
