Page 19: Operating Principle Of Ultrasonic Humidification
4.4. Operating principle of ultrasonic humidification Ultrasonic humidifiers from the STULZ UltraSonic model series work on the principle of ultrasonic atom- ization. A 48 V alternating voltage is rectified on an nebulizer print plate and converted into a high-fre- quency signal of 1.65 MHz. This signal is transferred to an transducer installed in the water bath, which converts it into a high-frequency mechanical oscillation. -
Page 20: Technical Data
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. -

Page 29: Humidifier Distance
Note Adiabatic behavior. STULZ UltraSonic humidifiers atomize the water in minuscule droplets (< 0.001 mm). The mist (aero- sols) produced in this way draws heat from the surrounding air (enthalpy) and changes its state from flu- id to aqueous. This "adiabatic" behavior (removal of heat from surrounding air) cools the air in the room. -
