Pre-commission & Chemical Cleaning

Pre-commission/chemical cleaning is achieved through a process of flushing and chemical cleaning, where required, followed by the addition of biocides and inhibitors. Systems designed and cleaned in accordance with BSRIA’s guidance are far less likely to experience operating problems.

Pre-commission/chemical cleaning can play an important role in boiler maintenance. Proper chemical cleaning removes deposits from the inside of boilers/chillers tubes which improves the boilers/chillers temperature rate, reduces tube failures and improves the stability of boiler/chiller chemistry.

Direct-Water offer a complete range of water treatment products and services to control scale and corrosion in domestic and industrial closed loop water systems. This includes; domestic central heating systems, closed heating/chilling systems, and steam boiler water treatment. Our flushing methods and biocide treatments help to prevent bacterial contamination and fouling issues, improves system water quality, and maximise heat exchange efficiency, providing system longevity.

We also carry the following services on closed loop circuits:

  • Chemical cleaning
  • Dosing of inhibitor/glycol/biocides
  • Cleaning/replacement of System/unit stainer(s)
  • Micro-biological water sampling of closed loop
  • Installation of dosing pot
  • Valve replacement
