Closed loop systems refer to heating or cooling systems that are typically not open to the atmosphere, so there is no evaporation and the entire volume of water is recirculated. Chilled water systems, used for comfort or process cooling, typically interact with an open cooling system through a chiller or other heat exchanger.
WET Solutions, Inc. water treatment consultants have extensive experience with the many types of closed loop systems and associated equipment, and we know through experience that these systems are often neglected. Just like open cooling systems, chilled water systems can suffer from corrosion, microbiological growth, and debris buildup. While surveying your facility, we will determine if there is proper filtration, chemical inhibition, and water treatment service for the closed loops.
