Adiabatic coolers (also called evaporative coolers) use water to cool air. Air is exposed to wetting pads, thin fill, plastic mesh or mist nozzles. As the air passes, water is evaporated, absorbing heat from the air. This results in a cooling effect. Through the process of evaporation, adiabatic coolers humidify the air. As water is potentially aerosolised, adiabatic coolers are considered a risk for water borne pathogens such as Legionella.
