Product description STULZ UltraSonic -System for duct humidication ENS 14 A - 18 A-
4.5. Technical data
The STULZ UltraSonic ENS ultrasonic humidier works on the principle of ultrasonic atomization. The
airow in the duct blows the mist, which was produced in a water tank with the aid of an transducer, into
the room to humidify it. The ultrasonic humidier consists of the atomization modules, the supply module
with solenoid valve that lets in the water supply, oat switches and a housing accommodating a fan. A
switch gear cabinet must be installed externally, which will house the open and closed-loop control sys-
tems and power supply for the unit.
