Heating and chilled water circuit remediation cleaning
Chilled Water (CHW) and Low Temperature Hot Water (LTHW) systems can 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 Water Treatment can provide rectification works that will:
- Minimise system disruption caused by blockages
- Increase system efficiency
- Increase system longevity
- Improve system performance
- Reduce system maintenance.

Latest techniques
We use the best methods and technology available, such as:
- Closed-loop pre-treatment cleaning (CPC), which significantly reduces the need to flush and drain the system, cutting cleaning times and water wastage, thus improving sustainability.
