4.9 Connection of evaporative humidifier

AHUs VS 21-650 can be provided with evaporative humidifier. Evaporative humidifier works on the
principle transmission of humidity by evaporation of water from the trickling pad into the air flow.
Humidify of this type is characterized by high efficiency and reliability.
Depending on the size of AHU, the used humidifiers will work on the water direct supplied (VS-21-55)
and circulation (VS 75-650).
