7. HUMIDIFIERS

7.1 STEAM HUMIDIFIER

Immersed electrode humidifier for comfort air conditioning applications. Humidifier consist of humidifier cabinet placed near air handling unit and 

steam distributors installed inside air handling unit section with stainless steel drip tray or inside air ductwork. Two humidifier types available: 

X-plus and Basic.

Water and electrical connection:

Refer to manufacturer’s operating instructions.

7.2 EVAPORATIVE HUMIDIFIER

Evaporative humidifier employ water evaporation produced by air currents. Used for air humidification or for indirect adiabatic cooling. Air passes 

through a sheet of water and partially evaporates it. The water vapour added to the air’s mix, which is at the same time cooled.

Technical data:

• Units with recirculation in order to save water or direct water units to reduce maintenance work.

• Optional UV lamp water treatment system.

Water and electrical connection:

Refer to manufacturer’s operating instructions.
