Overview
Introduction: The outlet temperature is controlled between 7 ° C and 35 ° C. Refrigeration power options: 3phase-220v/380v/415v/460v-50hz/60hz. Cooling capacity of the chiller unit: 20 tons to 150 tons. Semi closed screw compressor, air-cooled condenser, closed-loop shell and tube evaporator. No need to install a cooling tower
Product Details
MG air-cooled screw chillers are widely used in injection molding, extrusion, electroplating, molds, hydraulic, chemical, leather, printing, oxidation profiles, reaction vessels, chemical fibers, vacuum coating, papermaking, textiles, central air conditioning refrigeration, and centralized water supply in various fields. They are particularly suitable for water supply and ground water pipes, which may cause inconvenience.
As a leading supplier of air-cooled screw chillers, Megabert chillers offer a full range of MG-CS series air-cooled screw chillers with cooling capacities ranging from 50Ton to 580Ton/130KW to 1950KW, and the temperature control range of the cooler is+30 ℃ to -30 ℃.
In addition to the standard air-cooled screw refrigeration unit with a control temperature of 7 ℃ to 30 ℃, TopChiller also has an air-cooled ethylene glycol screw refrigeration unit with a control temperature from 0 ℃ to -30 ℃ below zero.
MG chillers have the following characteristics:
1. Use world-renowned brands of semi enclosed screw compressors - Bitzer from Germany and Handbell from Taiwan.
2. Each screw compressor has 4 energy control steps of 25% -50% -75% -100% to ensure the stability of the entire screw cooler and high refrigeration performance. According to the required cooling capacity, there are also 2 or 3 compressors available for selection.
3. An efficient closed-loop shell and tube heat exchanger is used as the evaporator, and an air-cooled condenser with copper tube sleeves and aluminum fins and a large air-cooled fan is adopted.
4. Integrated PLC control system with human-machine interface and large LED touch screen panel, easy to operate and troubleshoot.
World renowned refrigeration spare parts such as Danfoss brand thermal expansion valves, Alco dry filters, Schneider Electric contactors, and overload relays will ensure that the entire air-cooled screw refrigeration unit operates normally under normal conditions.
The above original quality refrigeration spare parts will ensure that each air-cooled screw refrigeration machine is in a stable operating state.
