Industrial chillers are crucial for maintaining optimal temperatures in plastic processing applications, including injection molding, extrusion, and blow molding. There are two primary types of chillers: air-cooled and water-cooled. Understanding the differences between the chillers can help you determine which is best suited for your specific cooling needs.
Industrial chillers are widely used across various industries, such as plastics manufacturing processes and automobile production. For plastics processing applications particularly, chillers are used to remove excess heat out of molds and machinery. Air-cooled chillers and water-cooled chillers are connected to injection molding machines or extruders for cooling effects.
Consistent temperature control units are important for plastics processing. By effectively removing excess heat, industrial chillers ensure product quality and shorten downtime.
An industrial chiller works by removing undesirable heat to achieve the desired temperature. The cooling process begins with the chiller circulating a refrigerant through a closed-loop system. The chiller absorbs heat from the process fluid or air.
The heated refrigerant then flows from the evaporator to the compressor, where it is pressurized into a vapour. This vapour is subsequently cooled and condensed into a liquid by either air or water in the condenser. The cooled refrigerant then returns to the evaporator to repeat the cycle.
As explained earlier, industrial chillers deliver a continuous flow of cooling water to remove heat. Ultimately, both chiller types provide the same cooling performance. However, the main difference between an air-cooled chiller or water-cooled chiller is the condenser type. Choosing between a chiller depends on factors such as the scale of operation, ambient conditions, and water availability.
