The "Hailing" brand series of industrial chillers can provide ice water with a temperature of 3-30 degrees, and the special low-temperature type can be as low as -25 C (the temperature difference does not exceed 1 C). Air-cooled chiller, cooling capacity from 1316-156245Kcal/h (compressor power from 0.5-60HP), can be widely used in various industries, such as injection molding, blister in the plastics industry, and the chiller can accurately control plastic molding molds The temperature can shorten the molding cycle and accelerate the product setting, so that the product does not deform and shrink, and can also improve the surface finish and enhance the perspective rate; it is also suitable for cooling CNC machine tools, coordinate boring machines, grinding machines, machining centers, combined machine tools and various precision machines. The cooling of the spindle lubricating oil and hydraulic transmission medium of the machine tool can accurately control the oil temperature.
