air washer

The circulating water spray humidifier, also known as an air washer, is the classic among humidification systems. The amount of water atomized within the airflow is many times greater than the water flow required for humidification. The water that has not evaporated is collected in a container and fed back to the nozzles.

The air washer is still the first choice, especially for requirements with very precise control accuracy in connection with high to very high humidification performance. Compared to other systems such as steam or high-pressure humidifiers, the air washer is also preferable from an economic and energetic point of view, especially with larger air volume flows and humidification.

The cleaning effect of the air is a positive side effect. Solid and gaseous compounds such as fine dust, pollen, spores (allergens) as well as sulfur oxides, nitrogen oxides, and ozone are absorbed to a large extent. The air washer is not only used to wash out NH3 but also as an AMC filter stage in clean rooms in semiconductor production.

Depending on the application, the circulating water spray humidifier differs in both technical and structural design. The focus is on individual design and adaptation to customer requirements.

The hygienic safety was checked by an independent organization and confirmed with the issuance of the certificate according to VDI 6022-1.
