Case Study- Steel Water Tanks at a University

Posted on December 20, 2012

In September, the COVAC team were asked to repair two heavily corroded sectional steel Braithwaite cold water storage tanks at a University in the North of England. With each storage tank sized at approximately 3.6m x 1.8m x 2.4m this was no small project.  The tanks had been previously coated with a non-approved bitumen which had degraded over time meaning we had a big job on our hands to restore the tanks and make them completely safe for use.

Case Study- Concrete Water Tanks at a Hospital in the North of England

Posted on November 23, 2012

Recently, the team at COVAC were set with the task of repairing and relining two concrete water tanks at a hospital in the North of England. With both tanks sized 8m x 5.5m x 3m and in need of considerable repair, this was a large scale project as the (now banned) bitumen based internal coating previously used on the tanks had reached the end of its useful life so needed to be replaced before any further problems arose.

What Problems are Associated with GRP Tanks?

Posted on October 26, 2012

COVAC can inform you of such problems to ensure you are fully aware and so can make an informed decision as to whether the purchase of a GRP tank is a sound investment for the future or if the refurbishment of your existing tank would be a better option.

Is there a way to prevent pseudomonas and other harmful bacteria from taking hold and creating health risks in your cooling tower? Well

Internal Surface Relining of AHUs

Posted on August 22, 2012

Subjected to incessant and aggressive conditions, air handling units (AHUs) often suffer from seriously corroded internal surfaces that need to be addressed quickly and effectively to prevent possible contamination from the Legionella bacteria which could lead to an outbreak of Legionnaire’s disease (recently highlighted in the popular BBC series ‘Holby City’). At COVAC we have been offering our expertise for over 15 years and as the market leader in AHU refurbishment using solvent free polyurethane technology we can offer a reliable AHU reline and refurbish service with a long term guarantee.

As the dominant company in this industry we pride ourselves on providing our clients with long-term protection that tackles the problem of AHU corrosion. Utilising the very best and most effective solvent-free, high performance technology, COVAC can help to reline your AHU with the very best product on the market.

We often discover that the original factory condition of the internal surfaces of Air Handling Units has simply broken down over time and constant use leading to micro aquatic bacterial growth on the corroded surface and contamination to the outlet.

It is now a legal requirement that your AHU complies with the guidance of ACOP L8, and therefore using products that meet with the water regulations is a must. Our solvent free, urethane coating offers a raft of economic and safety advantages, including:

•    Resisting the growth of bacteria such as Legionella;
•    Fast curing times even when exposed to low temperatures, thus reducing downtime;
•    Highly flexible to ensure it can accommodate structural movement;
•    High resistance to chemicals and impact;
•    Offers long-term protection with little need for maintenance.

At COVAC we believe that there is no other single coating product available that can match the durability and reliability that our service offers. If you’d like to find out more about our relining services for AHUs and cooling towers, click here and one of our knowledgeable and friendly team will gladly answer any questions you may have.

Legionnaires’ Outbreak in Edinburgh Declared Over

Posted on August 8, 2012

The outbreak of Legionnaires’ disease that resulted in the death of three men has been declared over by health officials. Since the outbreak emerged in May, a total of 101 people have been treated for Legionnaires’ disease as either confirmed or suspected cases. Although the outbreak has been declared over the NHS are still keeping a close eye on people as it is expected that more cases could emerge in people who have been ill for a long period of time.

Health chiefs have said that the fast response at the start of the outbreak meant that the disease was brought under control relatively quickly and efficiently. All suspected and confirmed cases fall within the expected incubation period, which is why the decision has been made to declare the outbreak as over.

Experts are still trying to find the exact source of the outbreak, but officials are doubtful that they will ever be able to pinpoint the exact source which led to the outbreak. However the main consensus is that it was caused by a cooling tower in the city of Edinburgh. A report outlining what happened is being produced; it will also include recommendations for the prevention and control of future outbreaks.

The legionnaire’s outbreak has led to many people calling for all cooling towers to be reviewed to ensure they are safe. COVAC can assess the condition of your cooling towers and carry out all the relevant work to ensure your cooling towers are corrosion free and easy to maintain thus heavily reducing the likelihood of your cooling tower being the source of a future outbreak of Legionnaires ’ disease.
