Chemical Cleaning – Heating and Chilled Water Circuits

Chemical-CleaningWe are able to provide a service to chemically clean heating and chilled circuits. By introducing polymer dispersants and sequestrian agents to remove iron oxides and magnetite sludge that cause fouling and a reduction in efficiency for which a chemical clean will cure.

Following the chemical cleaning, proprietary corrosion inhibitors are added and in certain circumstances biocides, to prevent microbiological proliferation.


  • Precommission cleaning in accordance with BSRIA code BG 29-2012
  • Chemical cleaning of heating and chilled water circuits 
  • Acid descaling of hot water calorifiers and boilers 
  • Boiler treatment 
  • Cooling tower maintenance

Recent successful projects include the pre commission cleaning of CHW and LTHW systems at:

Trend Controls, Horsham.
Southampton Civic Centre.
Savvis International, Reading.
