Water chillers (freezers) are widely used in the cooling of molding molds of plastic processing machinery. The water chillers can greatly improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, and the water chillers  can prevent the product from shrinking or deforming, which is convenient for plastic products. The demoulding speeds up the product shaping, thus greatly improving the production efficiency of the plastic molding machine. Water chillers (refrigerators) are used in CNC machine tools, coordinate boring machines, grinders, machining centers, modular machine tools, as well as various types of precision machine tool spindle lubrication and hydraulic system transmission medium cooling, which can accurately control the oil temperature and effectively reduce the thermal deformation of the machine tool , Improve the machining accuracy of the machine tool. Industrial chillers (refrigerators) come as a complete packaged closed-loop system, including cold and hot water units, condensers and circulating pumps, expansion valves, no flow shutoff, internal cold water tanks, and temperature control stations.
