“NWW supplies Scale , corrosion inhibitors and Biocide for closed chilled and Heat system.”
Closed circuit or closed loop water systems are a convenient way of heating or cooling building services applications and industrial and commercial processes. As the name closed loop suggests the intention is generally to retain the same water in the system for an indefinite period which means that without effective water treatment corrosion products and foulants can build up impairing flow and heat transfer and control valves can become blocked and inoperative.
