Pre-commission & Renovation cleaning chemicals & Services

Pre-commission Cleaning of Heating and Chilled Water Systems

New heating and chilled water systems require a pre-commission clean before being brought into service. There are two principal reasons for this: firstly to clean and prepare the metal surfaces for passivation with a corrosion inhibitor and secondly to mobilise the deposits and suspended solids so that they can be flushed from the system prior to commissioning and putting into service.

During construction the system can build-up corrosion products, construction debris, microbial slimes and other fouling. It is very important to clear this debris from the system before commissioning since it may be impossible to balance a dirty system and it won’t be long before close-tolerance control valves start to clog up with debris and stopping the system from operating correctly.  Effective corrosion inhibition will dramatically extend the life of a system and prevent future problems of fouling, however, for a corrosion inhibitor to work effectively the metal surfaces have to have been cleaned to allow a strong adherent inhibitor film to be established.

Feedwater have been making and supplying closed system cleaning agents and inhibitors for decades and we have extensive experience in cleaning the most challenging of systems. We can either carry out the work for you or supply you with the pre-commission cleaners and corrosion inhibitors so that you can do the work yourself.
