There are various types of closed water systems or closed recirculating water systems, notably chilled water systems (CHW) and heating water systems (LPHW, MPHW, HPHW). In a closed system, water circulates in a closed cycle and is subjected to alternate cooling and heating without contacting air.

Closed water systems are subject to corrosion, scaling, sludge formation and bio-fouling all of which can result in problems such as system lack of performance, reduced economy and increased maintenance and repair costs.
