Several metals are capable of being anodized, aluminum is the most common 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. The anodizing of aluminum is performed by making the part that is to be anodized, the “anode” or 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.
There are different types of anodizing: Type I Chromic Acid Anodizing, Type II Commercial Anodizing, Type III Hard Coat Anodizing, Titanium Anodizing, Impregnation, and Chromate Anodizing. Regardless of the type, the anodizing process generates a lot of heat and 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.
Sizing a chiller is extremely important regardless of the industry. Fully understanding the anodizing process becomes imperative because the different anodizing types require different temperatures. At BV Thermal Systems, we have the knowledge and experience necessary to to accurately size a chiller based upon your process and requirements.
The environmentally friendly Anodizing Chillers offer continuous cooling with temperature from +5° to +70°C. Featuring a low profile design with high quality locking casters, the cost effective Recirculating Chillers provide a small footprint with exceptional performance and unmatched reliability.
Manufactured and thoroughly tested in the United States the Anodizing Chillers feature a hot gas by-pass which allows for greater stability and thermal protection for the pump, motor and compressor. With simplicity in design and operation, the BV Thermal Systems’ Recirculating Chiller is designed to provide years of reliable liquid temperature control.
