Cooling Tower Cleaning

A well run cooling tower/evaporative condenser is the most efficient means of removing heat from a system as they are smaller (footprint) and consume less energy per joule to lower coolant temperatures than other cooling systems.

Cooling Tower Cleaning is essential as potential dangers of bacterial contamination as warm water is passed over baffles in the presence of a flow of air. These dangers and the legal requirements of tower owners/operators are set out in the HSE Approved Code of Practice and Guidance ACoP L8 And HSG 274 pt 1.

Correct dosing of inhibitors and biocides (Control and Dosing), together with monitoring, sampling and Cooling Tower Cleaning is key to overcoming these problems leading to long-term trouble free running. We specialise in providing and commissioning automated water chemistry regulation systems.

By mitigating corrosion, through the use of inhibitors, our Cooling Tower Cleaning service prolongs the life of the equipment and deny nutrients to bacteria. The inhibitors also help to prevent scale build which prevents clogging of the system and removes another source of nutrient. Less scale helps maintain a clean system in which the biocides can work more effectively.

A Cooling Tower Cleaning programme incorporating control and treatment but vigorously backed up with monitoring, sampling and cleaning needs to be tailored to each site. Therefore we offer:

  • Risk Assessment
  • Scale & Corrosion – Treatment and Control
  • Chemical Supply
  • Controller Supply and Commissioning
  • Tower Installation and Refurbishment
  • Physical and chemical monitoring
  • Legionella and water chemistry sampling
  • Cleaning and disinfection
  • Support for HSE/EHO inspections

We like to stress the importance of maintaining a clean cooling tower as bacteria can easily build up and lead to Legionella forming , we advise that your cooling tower should be thoroughly disinfected at least twice a year to prevent this.


As a company we want to provide the best service we can to our customers, this means that we are more than happy to answer any inquiries you may have about the wide range of services that we provide. Our company has long term expertise in water cooling tower design, supply and construction. This means that we are able to provide our customers with exactly what they need. We want to minimize our customer’s energy, water, and maintenance costs while ensuring safe and reliable operation of these critical systems. So if you want to drastically reduce your cooling systems operating costs, increase cooling efficiency, and minimize the operation challenges of your cooling towers, contacts us!


It is a requirement of the ACoP L8 that regular TVC and Legionella sampling is undertaken at a UKAS accredited laboratory.
