Cooling towers and evaporative condensers are systems that use water, usually falling within a tower, to cool hot air from an industrial process or air conditioning systems. If not properly maintained, droplets of water from such systems can be a source of Legionella a pneumonia-like infection, which is especially dangerous to certain individuals (the most at risk being men over 50 years of age who smoke) .
