Hengde chillers can be classified by type into air-cooled chillers and water-cooled chillers. According to compressor structure, they are divided into scroll chillers, piston chillers, and screw chillers. Based on chilled water outlet temperature, they are categorized as standard chillers (above 0℃) and low-temperature chillers (below 0℃). These chillers find extensive applications in various industries, including plastics and rubber (injection molding, blister molding, extrusion, bottle blowing, etc.), food and beverages, electronics, chemicals (primarily for reaction temperature control), surface treatment (such as electroplating process), marine, automotive interior parts, die casting, textiles, and more. They are often referred to as marine chillers, electroplating chillers, beer fermentation chillers, concrete mixing station chillers, and so on.
