Closed System Water Treatment (Pre-commission Cleaning)

Closed System Water Treatment in relation to heating, cooling and other closed pipework systems is the process of bringing the water system to a satisfactory condition for commissioning and maintenance of water quality.

Water System Contaminants

System contaminants such as mill scale, jointing compounds and building debris are likely to be found in newly made-up heating and cooling pipework systems. If this debris is left in the water system and builds up over time these contaminants will make the system prone to blockages.

Further corrosion of the pipes is likely and this will eventually encourage the growth of micro-organisms such as Legionella.

The necessity of this water treatment in recent years has increased and this is due to modern day heating and cooling systems moving towards energy efficient control strategies that result in low flow rates in terminal units with consequently very small orifices in control valves.
