Drycool manufactures chiller systems including water and air cooled chillers for removing the process heat generated by anodizing. Because the anodizing process generates a lot of heat, cooling is a must, particularly for hard coating processes. Anodizing chillers 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.
