250kw Glycol Low Temperature Chiller
The application range of the low temperature chiller is very wide, and the cold volume generated by the low temperature chiller is often transported over a long distance, so some auxiliary equipment and auxiliary medium are needed. The cooling capacity is obtained in the evaporator of the low temperature chiller, and then the cooling amount generated by the low temperature chiller is transferred to the object to be cooled, and the intermediate medium for carrying the cooling capacity is called the low temperature chiller coolant. Commonly used low-temperature chiller coolants include water, salts (calcium chloride, sodium chloride, etc.) and organic matter (ethanol, ethylene glycol, etc.).
As a low-temperature chiller coolant, it should be non-toxic, chemically stable, less corrosive to metals, non-tender, low freezing point, large heat capacity, small specific gravity, low dryness, high thermal conductivity and low price. A series of conditions.
This 250kw glycol low temperature chiller unit adopt double screw compressor,with tank and pump inside to produce -20C glycol outlet.
