Durable Cooling Tower Refurbishment

Posted on October 4, 2011

It is of paramount importance to ensure that the interior surface of cooling towers is both clean and bacteria free to reduce the risks of Legionella contamination. At COVAC our professional team of experts can provide reliable and efficient cooling tower refurbishment in order to ensure your cooling towers are in the best possible condition and are easy to clean during future maintenance.



Even if the cooling tower has an existing coating it may not have the chemical resistance or elongation properties required and we often see existing coatings delaminating from the substrate leaving it vulnerable to further corrosion and contamination. The internal surfaces of cooling towers can also come into direct contact with chemicals that pass through it making the internal substrate even more susceptible to corrosion and subsequent deterioration.

If this corrosion is neglected, eventually the internal steel surface will be at risk of progressive corrosion that will lead to the growth of micro aquatic bacteria such as Legionella. We are all now under legal obligation to ensure that we adhere to regulations set in the practical guidance of ACOP L8, designed to prevent such contaminations from spreading from the surfaces of cooling towers.

Another ongoing problem with cooling towers is the mastic between the joints which, over time, begins to deteriorate and lose its elasticity and this, coupled with the movement associated with this type of structure, can cause leaks that can be catastrophic.

With the pressure of eradicating such serious dangers in mind, it is vitally important that you seek the services of a professional team like the one in operation at COVAC, to provide efficient and reliable cooling tower repairs and refurbishment.
