Legionella

Cooling towers and evaporative condensers, as a rule, looked unfavorably, because they are inevitably associated with legionella. Legionnaires ' disease caused by the inhalation of small drops of water, for example, can be dispersed from these heat exchangers, when infected with the bacterium legionella. The bacterium is a very common and can be found in tap water, so there is no chance of preventing access. Only when conditions allow rapid multiplication that there is any risk.

Due to the need for a compulsory examination and fear made switch off on suspicion that the device may be the cause of the fall of Legionnaires ' disease, there has been a shift in the direction of the air-cooled units. Controls to reduce the risk of legionella effective in the UK, but, nevertheless, there remains a need for vigilance (Oughton, 1987). Type evaporative condenser, which does not require a reservoir, known as " one-off " type, can eliminate the risk. The events reported Pearson (2006).....
