Central Chilling Systems For Anodizing

Sep 2020 – Temperature Corporation manufactures central chiller systems for removing the process heat generated by anodizing, plating and other metal coating processes.

Because the anodizing process generates a lot of heat, cooling is a must, especially for those hard coating processes. Our central chilling systems will do most of the work, removing process heat using either an air or water cooled chiller. Air cooled units are generally installed outside, and eliminate the need for a tower. Water cooled units are the most efficient method, particularly in warmer climates. They are installed inside a building with a cooling tower outside.

How Anodzing Works

Several metals are capable of being anodized. Aluminum is the most obvious candidate, but the process may also be applied to magnesium, titanium, and tantalum. Anodizing is an “electrochemical conversion process” that changes the outer structure of the metal, rather than an applied coating, like paint. The anodizing of aluminum is performed by making the part that is to be anodized, the “anode” a positive end of an electrical circuit within an acid electrolyte. With electricity applied through the acid from the cathode, an oxide layer develops in and on the outer layer of the metal. This outer layer can be formed so that it has a porous quality and the aluminum oxide layer can be dyed in many colors.

Temperature Corporation designs central chilling systems for the anodizing and metal plating industry. Our modular approach allows chillers to be added to the central system easily without shutting down the existing system. Combined with our chilled water and tower water pump packages, you have a complete cooling system that communicates the operating and fault conditions of each piece of anodizing equipment in the system to your plant PLC and can be expanded as your plant grows.

Our central chillers are available in four different configurations: indoor water cooled, indoor air cooled, outdoor air cooled and remote condenser air cooled and all are available with Dual Scroll compressors, or Single Screw compressors. The modular chillers offer a system that can be easily expanded, take up minimal plant floor space and can be serviced in place without shutting down the rest of the chiller system.
