Portable25 Ton Air Cooled Chiller Glycol Water Chiller Low Temperature Water Chiller Laboratory Low Temperature Circulation
Low Temperature Glycol Chiller
Low temperature glycol 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.
Air-cooled chiller is built-in insulation water tank and water pump, no need to add another cooling tower to heat. It is very easy to install and move. But it has high requirements on the working environment. It is cooled by hot air circulation, so if the ventilation effect of the installation workshop is not good, it will directly affect the refrigeration effect of the chiller.
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.
