Applications of Cooling Tower Refurbishment ProductsPosted on November 1, 2011
Untreated cooling towers can pose potential, serious health risks. Because cooling towers are used to transfer heat waste into the atmosphere, it is vitally important that the tower is regularly maintained to reduce the risk of contamination to people within the surrounding areas. Here at COVAC we specialise in professional cooling tower refurbishment complete with a minimum 10 year guarantee against future leaking and corrosion to give you peace of mind that your company are not jeopardising the health of the local community via your cooling tower.
Such are the growing health and safety concerns regarding the serious implications of untreated cooling tower use, the government have introduced legislation designed to encourage companies to ensure the safe operation of maintained and sufficiently treated cooling towers in order to reduce potential health risks.
Health and safety concerns can arise from a cooling tower that does not have a professionally coated internal surface. Many cooling towers are often coated in non-approved (WRAS/DWI) paint such as bitumen or epoxy. These coatings can provide minimal levels of chemical resistance and corrosion is inevitable.
The internal steel substrates of the cooling tower are at genuine risk of progressive corrosion with continued use and micro aquatic bacterial growth soon occurs inside the cooling tower. One common bacteria that can be found within cooling towers is Legionella – the bacteria that causes the potentially fatal Legionnaires disease.
Legionella bacteria are common in natural water courses such as rivers and ponds. Since legionella are widespread in the environment, they may contaminate and grow in other water systems such as cooling towers and hot and cold water services. They survive low temperatures and thrive at temperatures between 20-45°C if the conditions are right, e.g. if a supply of nutrients is present such as rust, sludge, scale, algae and other bacteria.
When water carrying heat waste passes through the contaminated cooling tower, potentially deadly bacterium is carried through and transferred into the atmosphere posing a serious risk to the welfare of people living and working in the surrounding areas.
At COVAC we can help you to maintain your cooling tower to ensure you are not putting lives at risk. Our specialists can refurbish your cooling tower using the specially formulated 3M™ Scotchkote™ Urethane Coating 165PW. This WRAS and DWI approved solvent-free technology provides a long-lasting cooling tower coating with an easy clean, ceramic tile-like finish, meaning that future cleaning and maintenance is much easier and quicker thus preventing the build up of the nutrients that feed the potentially fatal bacteria.
