Chemical Cleaning Services

The importance of Chemical Cleaning of Industrial Equipments is now being increasingly realised by Industries having Equipments where water being used either heating or cooling purpose and constant effort is given to keep the heat transfer surface free from scales and deposits by periodic Chemical Cleaning of these Equipments under routine maintenance programme. However good the Control chemistry may be, the build-up of the certain amount of scale/deposit over the heat transfer surface is unavoidable.


The Plant efficiency and fuel economy is to a great extent depends on the water side scale control. Scales, deposits, corrosion and micro-biological fouling in a Cooling / Boiler Water System are highly objectionable because of their thermal insulation and low thermal conductivity. It is known that the scale has a thermal conductivity only 3-4% than that of steel. Therefore, Chemical Cleaning is now considered on priority for maintaining the equipment which pertains to fuel efficiency, economy, safety and reduction of down time due to unscheduled shut down.


Chemical Cleaning is a highly skilled job. It does not mean only circulation of virgin acids. It needs development of suitable solvent on the basis of physical and chemical testing of the representative sample (Deposit) from critical points in the system, metallurgy of the system, flow distribution within the equipment etc. etc. An appropriate Procedure and Sequence of Operation is an essential part for successful Chemical Cleaning Operation. With the advent of advance chemicals like surfactant, dispersant, complexing and sequestering agents with high performance corrosion inhibitors, Chemical Cleaning has now become a safe and specialized job under experienced supervision.

 Advantages Of Chemical Cleaning:


  • Uniform and better cleaning
  • No extensive dismantling 
  • Minimum down time 
  • Inaccessible areas, are readily cleaned.
  • Chemical Cleaning is economical.
