Evaporative cooling and Legionella: a risk which can be prevented by using good practices, 18th Informatory Note on refrigerating technologies.

Type of article: Techincal Brief

Summary

Legionella pneumophila, the causative agent of legionellosis, is found in aqueous environments. The sources of contamination are hot water distribution systems (showers, etc.), evaporative cooling systems such as wet cooling towers and evaporative condensers and all devices generating small, breathable, hot water droplets. The sectors concerned are industry, commercial (hotels, office buildings and shopping centres, etc.), health (hospitals) and residential. Unitary air conditioners, and more generally all types of equipment that use air-cooled condensers, cannot be a source of legionellosis. See also this Bulletin, reference 2006-2618.
