Chemical cleaning

Cooling tower algae stain

Chemical cleaning will ensure your plant operates efficiently and will prolong its life expectancy. It can help reduce costly repairs and make plant maintenance easier and safer by minimising risk. This is done by removing potential environmental hazards and unwanted deposition caused by calcareous deposits, and corrosion from internal waterways in plant, systems, piping and equipment. 

Our experienced team of technicians, supported by specialist engineers and chemists, plan, and conduct the necessary cleaning requirements within scope, budget, and timeframes. 

We have extensive experience in chemical cleaning and the removal of materials including: 

  • Oils
  • Corrosion products 
  • Water hardness deposits
  • Biofouling

This can be conducted using a variety of applications in a diverse array of plant and equipment that include: 

  • Industrial steam raising plant and auxiliaries
  • Industrial process equipment
  • Lubrication systems
  • Heat exchangers
  • Pipelines
  • Cooling systems
  • Vessels


Acidic foam procedure 

We offer a sophisticated foam treatment application for superior cleaning results for the chemical cleaning of cooling tower packs in situ.

Costain Pack-Clean is designed to clean by dissolving scale deposits and disinfecting cooling tower surfaces. On lightly scaled and fouled systems it is used as a replacement for packing removal and as a method for lengthening the pack media lifecycle. 

During the cooling tower inspection, which includes an endoscopic survey, our qualified team of cleaning technicians will use the most suitable product based on deposit analysis, materials of construction of the unit and environment. 

Benefits of acidic foam procedures over traditional products: 

  • Strong clinging foam to give optimum contact time
  • Acidic foam cleaner for periodic cleaning applications - effective scale remover 
  • Inorganic acid with high foaming agents ensures fast removal of calcification and other deposits from the cooling pack

Our chemical cleaning services will enable your organisation to make making substantial savings and efficiencies through:

  • Reduced downtime
  • Reduced fuel costs
  • Reduced repair costs
