Glycol Water Chiller Unit Glycol Cooler Brine Chiller Water Cooled Glycol Chiller Manufacturer Glycol Water Cooling Chiller
Glycol Water Chiller - Low-Temperature Chillers
Low temperature chiller is a kind of water cooling equipment, it can provide a constant temperature, constant current, constant pressure of a cooling equipment. The glycol chiller water is between -5℃ and -40℃ and the chilled water will be transported to the equipment or products that need cooling through chiller pump.
Application
Industrial glycol water chiller unit is used to cool the hot parts of the equipment, so that the equipment can work normally at low temperature. Used in Beverage filling, spindle cooling, CNC machine tools, grinding miller, reaction system, welding machine, cutting machine and other equipment, temperature adjustment range can be 40 degrees below zero.
