China Low Temperature Chiller Supplier

The Low Temperature Chiller of AQWK is widely used in industrial production, especially in the field of mold forming, and has the following characteristics:

The advanced PID controller can accurately control the mold temperature. The general temperature control accuracy can reach ±1ºC or even higher, ensuring that the mold maintains a stable temperature during the production process, improving the quality of product molding, and reducing dimensional deviations and surface defects. Screw Water Chiller has two types for air cooled screw chiller and water cooled screw chiller. The cooling capacity can be selected from 90KW to 1200KW, It will be suggested adopt scroll compressor water chiller when cooling capacity less than 90KW. Max cooling temperature reach to -25.

Application Scope

Screw chiller is mainly applied to building industry and industrial cooling process in molding of plastic film and PE plastics bag or other industries. The chiller will greatly improve quality of molded products and shorten period of injection molding cycles.

Working Principle

Air cooled chiller condenser coils always have plenty of fresh air. When the refrigerant reaches the condenser coils, the fresh air absorbs the heat. The proportional integral derivative (PID) temperature controller prevents harm from high temperatures and has a set scale that can be used to shut off the unit. Cooling fans connected with the condenser provide a constant fresh air supply. Heat is exchanged by the liquid refrigerant in a corrosion-resistant shell and tube heat exchanger.Industrial chiller is a refrigeration system used to cool processes, equipments, or materials in various industrial applications. It works by removing heat from a liquid (usually water or a water-glycol mixture) through a vapor-compression or absorption refrigeration cycle. The chilled liquid is then circulated through a heat exchanger or directly to the equipment needing cooling, where the heat is absorbed and transferred to a secondary fluid. cooled water chiller is mainly applied to a cooling process in molding of plastic film and PE plastics bag or other industries. The chiller will greatly improve quality of molded products and shorten period of injection molding cycles. The max different is the way of heat radiation by fans with water cooled chiller.

There are three main interrelated systems: refrigerant circulation system, water circulation system, electrical control system.
