Whilst many see the replacement of an existing steel water tank with a brand new GRP (Glass Reinforced Plastic) tank as the ‘ultimate solution’, there are still a few important things to bear in mind and potential problems that should be considered. 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.

Alongside legionella (a bacterial growth that can lead to legionnaires disease which we have covered a lot lately due to the outbreak) and Biofilm, another harmful bacteria group that can thrive in poorly maintained cooling towers is Pseudomonas – a growth that can lead to various health and hygiene problems. Is there a way to prevent pseudomonas and other harmful bacteria from taking hold and creating health risks in your cooling tower? Well
luckily there is, COVAC are experts in cooling tower coating, repair and refurbishment. Continue Reading

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.

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.

You are sure to have heard in recent weeks of the outbreak of Legionnaires’ disease in Edinburgh and that cooling towers or Air Handling Units (AHU) are said to be the possible culprit. Although this has not been confirmed and officials have claimed that the cause of the outbreak may never be confirmed, it is highly probable that cooling towers or AHU’s in poor condition are likely to be to blame. The importance of ensuring that your cooling towers are maintained to high standards has been highlighted and COVAC urge you to assess your cooling towers and invest in cooling tower repair to rectify/prevent any problems.
Since the Legionnaires’ outbreak in Edinburgh, the number of confirmed and suspected cases has been steadily rising and sadly, the number of deaths is also rising. There has been a third death reported in the Edinburgh area. The number of confirmed cases on 9th July 2012 reached 49 while there are 50 suspected cases. The cause of this outbreak is thought to be cooling towers in the south of Edinburgh. There have been no further cases reported in other areas of the country; however, the outbreak has sparked a cry for all premises to review the condition of their cooling towers to prevent further outbreaks in the future.
Legionnaires’ disease is caused by bacteria called Legionella; Legionella can multiply rapidly if in the right conditions and if your cooling towers are not maintained properly they could become the perfect breeding ground for Legionella. COVAC offer a reliable and efficient cooling tower repair and relining service which could help you to prevent your cooling tower breeding Legionella bacteria.
Even with correct maintenance and water treatment the surfaces of cooling towers can become corroded, which makes cleaning very difficult and additionally, the corrosion provides an excellent food source and ideal breeding ground for the Legionella bacteria. If you’re worried about the condition of your cooling towers, we urge you not to ignore it or push it the back of your mind, investment now can prove very cost effective in the long term.
Whatever maintenance and refurbishment your cooling towers require, we should be your first port of call. Please browse our website to find out more information or call us on 08000 484609 with any questions or enquiries that you may have.cooling tower repair
With Legionnaires disease continuing to sweep Edinburgh, and the victim count on the rise, there is no better time to wise up on this incredibly harmful, airborne disease, and the importance of lining and cooling tower coating to protect it from contamination, ensuring it isn’t responsible for the possible 7KM spread of this potentially fatal pneumonia spreading infection. COVAC can assist to make sure your cooling tower is as safe as can be.
As an up to date figure, the number of cases in Edinburgh has now risen to an astonishing 95, with 48 confirmed and 47 suspected, the disease is seemingly rampant in the area. Three patients are currently in intensive care, whilst the rest are in differing states of infection.
Legionnaire’s disease is a dangerous infection that has caused trouble in the past, most notably in 2004 when an outbreak in France resulted in 18 deaths over 86 cases. The culprit in this case was, in fact, a cooling tower in a petrochemical plant. The chemicals travelled over seven kilometres to infect some of the cases in this instance.
The source of the bacterium is almost always water supplies, and when tiny droplets of infected water splash out into the environment, the bacterium stays in the air, invisible, able to travel and easily inhaled.
Naturally, the most important thing to do in this situation is to protect your environment by being absolutely certain your cooling tower is cared for, protected from corrosion or a substrate that could potentially harbour bacteria. COVAC have the professional expertise and experience to do this, ensuring your cooling tower is thoroughly relined using a solvent free urethane coating system. If your tower is corroded in any way, this is the ideal breeding environment for the bacteria that contains Legionella and as such should be repaired and relined. The good news is that it CAN be refurbished, and a replacement isn’t usually required.
Our qualified, trained specialists are ready to help ensure your cooling tower isn’t the source of an outbreak, and with a friendly and knowledgeable service nurtured by putting our customers first, COVAC are your complete anti-Legionnaires disease solution.cooling tower coating
The spread of the outbreak of Legionnaires disease which struck the Edinburgh area recently seems to have slowed. There has been two fatalities, 39 confirmed cases and a further 49 suspected cases to date, however more cases are expected. The Health and Safety Executive (HSE) and Edinburgh council are still trying to trace the source of the outbreak. A distillery Company and a pharmaceutical Company have so far been served with improvement notices on their cooling towers but the precise source of the outbreak may never be known.
Very often even companies that are dosing their cooling towers correctly can still have problems. If the cooling tower substrates and bolts holding the panels together are corroded they cannot be cleaned effectively, additionally, this corrosion provides an ideal food source for the Legionella bacteria along with a safe haven from the chemicals trying to eradicate them.
To combat these problems COVAC can expertly repair and completely reline the internal surfaces of cooling towers with a water industry approved, solvent free urethane coating system. This coating system provides a flexible yet impact resistant lining with an easy clean, ceramic tile like finish making future maintenance and water treatment so much easier and more effective.
COVAC offer a minimum 10 year guarantee against corrosion, erosion and leaking on all work undertaken making relining cooling towers a very cost effective solution.

One man has died and a further 51 people are fighting for their lives in an outbreak of Legionnaires’ disease in Edinburgh, further cases are expected . 16 Cooling Towers in the area are suspected as a possible source of the outbreak.
A potentially fatal form of pneumonia caused by the Legionella bacteria and contracted by inhaling contaminated water droplets. Cooling Towers are frequently the cause of an outbreak of Legionnaires Disease and a contaminated Cooling Tower is reportedly capable of spreading the disease over a 44 mile radius.
No, but if not correctly maintained Cooling towers over time can develop corrosion on the internal surfaces which provide food and an ideal breeding ground for bacteria such as Legionella. The corroded surfaces are also far more difficult to clean and treat during regular maintenance.
No, even a badly corroded tower can be repaired, prepared and relined in accordance with ACoP L8 guidelines using an industry approved coating such as those supplied and applied by a reputable Company such as COVAC.
