Pre-Commission Cleaning

The pre-commission cleaning of hot water heating and chilled systems has become more important over recent years, due to the equipment used being more susceptible to blockages at strainers, control valves and small bore heat exchangers. System contaminants such as millscale, jointing compounds and fabricating debris need to be removed by chemical cleaning and high velocity flushing, which will then allow the on-going water treatment regime to work effectively in preventing corrosion and microbiological fouling. Older systems that have accumulated deposits due to lack of the correct water treatment can
