Pre-commissioning cleaning for closed water systems

Guardian’s pre-commissioning cleaning services will keep closed water systems free from contamination at the outset, which, alongside a proper regime of servicing and maintenance, assists in safe and reliable performance.

Pre-commissioning cleaning is a standard requirement of all new closed water installations under the latest BSRIA guidelines, the industry recognised best practice control. Closed water systems that are not prepared correctly at the construction phase can fall foul of a number of problems, including:

  • High energy consumption
  • Blockages caused by the build-up of sludge or debris
  • Leaks and system failure
  • Contamination (bacterial or mixed metals) which can cause compliance issues

All of our clients have access to GuardianCare, an online reporting system that enables works relating to a specific site to be viewed in real-time. No more waiting weeks for paperwork to arrive – all relevant documents, certificates, engineers’ work sheets or any other information can be viewed on-screen and printed instantly.

Pre-commissioning and renovation cleaning

We provide pre-commissioning, and renovation chemical cleaning on live systems, as well our innovative non-chemical solution, Advanced Oxidation Technology (AOT) from Wallenius. AOT can be used on incoming mains supplies at the construction stage to provide a safe, environmentally-friendly and cost-effective alternative to chemical dosing of fill water.  AOT can also be used to control bacterial growth in existing water systems.

Heating and chilled water circuit remediation cleaning

Water systems can also become fouled at a later date, due to system alterations, inadequate maintenance of water chemistry, microbiological contamination or if proper pre-commissioning cleaning wasn’t carried out in the first place.  Although the cleaning of a fouled system can never render it ‘as new’, Guardian can provide rectification works that will:

  • Minimise system disruption caused by blockages
  • Increase system efficiency
  • Increase system longevity
  • Improve system performance
  • Reduce system maintenance.
