The application scope and role of chiller: Plastic industry: precisely control the mold temperature of various plastic processing; shorten the cycle of molding, ensure the product quality stability. Electronics industry: stabilize the electronic components internal molecular structure on the production line, improve the passing rate; used in the ultrasonic cleaning industry, effectively prevent expensive cleaning agent volatilizing and damage caused by this volatilization. Electroplating industry: control plating temperature, increase the density of plated units and smoothness, shorten the cycle of plating, enhance the productivity, improve product quality. Machinery industry: control pressure oil temperature in hydraulic system; stabilize the oil temperature and pressure; extend the oil operating time; improve the efficiency of machinery lubrication, reduce the wear and tear. Construction industry: supply chilled water used in concrete, make the concrete molecular structure fit for the construction purposes, effectively enhance the hardness and toughness of the concretes. Vacuum coating: control the temperature of vacuum coating machine, to ensure the high quality of coated units. Food industry: used in the high-speed cooling in food processing, to meet the packaging requirements; control the temperature of fermented food Chemical fiber industry: freeze and dry the air, to ensure the product quality.
