Cooling of Plated Solutions
Cooling of plated solutions is not easy task. With regulations set with the EPA, water shortages, disposal costs, maintain solution temperatures Whaley Products can help reduce these hardships. Cooling of solutions is important for the electrolyte solution to have a reaction properly. Each solution requires a different type of temperature.
Temperatures can change due to a variety of factors. These can include tank size, temperatures of plating room, temperature of parts being plated, and weight of parts. Solutions can be cooled by cooling towers and chillers that use city water or well water. Hardness and Mineral content must be checked, so solutions do not become contaminated. Softeners and filters can be used to stop this problem.
Chillers and cooling towers can be air or water cooled. Air cooled units are normally located outside next, or on top of the building. Fans and condensers are used to help maintain ambient temperatures year round. Water cooled units are designed for indoor use. These units can use refrigerants such as glycol, water, or glycol mixed with water to monitor temperatures.
Examples are listed in a chart below.
