Cooling Towers

Without effective water treatment, your cooling water system for refrigeration plants and/or air conditioning systems, can suffer from one or more of several issues.

Cooling Tower Water Treatment is an essential process for areas that typically involve Conditioning, Furnace Systems, Heat Treatment Processes and Refrigeration.

The cooling system may consist of a cooling tower, evaporative condenser or other cooling element, the re-circulating pipework, the heat exchanger, pumps and ancillary items such as supply tanks and pre-treatment equipment.

Advanced Water Technologies have the expertise to advise on and implement cooling water treatment programs that will eliminate the problems posed by corrosion, scaling, fouling and biocontamination.

Chemical water treatment is a vital part of cooling tower management to prevent both the build up of Legionella and to prolong the service life of components.

The Notification of Cooling Towers and Evaporative Condenser Regulations 1992 require the notification of wet cooling towers and evaporative condensers to local authorities in whose area the equipment is situated, regardless of whether the local authority or Health and Safety Executive is the enforcing authority.

Fouled cooling towers and systems have been shown to reduce efficiency by 40% to 50%. This inefficiency increases operating costs which may not be in the budget. Most companies perform a risk management process to determine the frequency of Cooling Tower Cleaning but it is generally accepted practice to clean a cooling tower twice a year.

Cooling Tower cleaning is essential to reduce the build up of accumulated nutrients; a primary cause of Legionella growth. Another problem is water that contains salts such as magnesium carbonate and calcium carbonate which are less soluble in hot water than they are in cold.

Water tank cleaning is an important part of water hygiene. Neglected water tanks can be the perfect breeding ground for harmful bacteria including Legionella, E coli and TVC which can be present in water tanks for numerous reasons.
