Product description
STULZ UltraSonic -System for duct humidification ENS 14 A - 18 A-
4.5.
Technical data
The STULZ UltraSonic ENS ultrasonic humidifier works on the principle of ultrasonic atomization. The
airflow 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 humidifier consists of the atomization modules, the supply module
with solenoid valve that lets in the water supply, float 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.
