19. CLEANING AND DISINFECTION.
19.1. Evaporative humidification: a natural method that does not carry bacteria.
The operational features of evaporative humidifiers are based on the natural effect of the water evaporation
when an air flow goes through/by a wet surface (is the same natural principle that occurs when water
evaporates from waterfalls, rivers, lakes, seas...).
Evaporation means that the water leaves the humidifier as pure vapour (gas). Minerals and eventual pollutants
stay in the water and can be eventually drained / eliminated. With no droplets or aerosols carry over, the
bacteria can’t be transferred to the humidified air. It is important to use a droplet separator when it’s needed.
The evaporative humidifiers work with water temperatures below 24°C, very far from the optimal growth
temperatures of the bacteria present in the water, essentially Legionella pneumophila , with an optimum growth
temperature of 37-41ºC.
The water basin, manifold, irrigation system and the other components of the HEF2 series are specially
designed for there to be complete emptying by gravity, without the aid of mechanical elements. Based on the
quality of treated air and water supply, a cleaning and emptying inspection plan should be established.
19.2. Cleaning
19.2 A. General
An inspection, emptying and cleaning plan must be established for the HEF2 Series depending on the treated
air and feed water quality.
Evaporation humidifiers should be cleaned regularly to prevent contamination. All the component surfaces
(panel, pipes and especially the water deposit) must be disinfected with an appropriate solution.
A cleaning process must be carried out once a year to maximize the useful life of the Cassettes.
Special attention must be paid to the cleanliness of the piping system, especially where it diverts; and the
cleaning process must reach all parts of the system.
