fine mist using high-frequency vibrations (1.7 MHz).
Treated water enters the humidifier's reservoir from an inlet located at the bottom of the unit. The water that enters
the humidifier's reservoir must be treated to remove minerals, bacteria and fungi, and should otherwise be pure to
prolong the service cycle of the unit and, above all, safeguard the public. An accumulation of minerals will result
in scale, and an accumulation of bacteria and fungi will result in unhygienic conditions in the space. Refer to
.
Transducers in the reservoir receive a signal for humidification and will activate. The transducers will vibrate in
the water to create a mist of fine water particles. The mist rate is controlled through the humidifier's control board,
and may be modulated on demand or on humidity signal.
The mist is blown from the reservoir into flexible tubes that exit from the top of the humidifier. The mist is
channeled directly into the Ultrasonic Blower Pack. The water particles in the mist are then absorbed into the air
and increase the relative humidity of the space.
Condensate formed in the flexible tubes between the blower pack and the humidifier re-enters the reservoir where
it can be reused.
Water is drained from the reservoir through an outlet located at the bottom of the unit.
Water Supply
Water enters the humidifier through the fill valve into the fill cup with integral air gap, and then flows down through
the UV light into the water reservoir
Water Level Monitoring
The water level in the reservoir is continuously monitored with a level sensor. If the water level drops below the
sensor switching point, from normal operation, the sensor supplies a signal to the controller. This opens the inlet
valve and the water reservoir is filled. When the water level reaches the operating level the sensor supplies a
signal to the controller to close the inlet valve.
UV Pre-Treatment
Water enters the UV reactor, from the inlet, and is disinfected with UV radiation in the UV reactor in the UV
assembly. The water exits the UV assembly into the fill cup which monitors the water level.
Mist Generation
When the humidifier receives a signal to supply mist, the unit fan and the piezoelectric transducers start
operating. The fine mist is blown out of the humidifier outlets by the unit fan.
Air Supply
Air supplied to the humidifier comes from the space surrounding the humidifier and through the humidifier. The air
should be filtered and clean to prevent contaminating the mist with microorganisms and dust.
The use of the supplied air filters (recommended) is advised for the Ultrasonic Humidifier and Ultrasonic Blower
Pack.
Flushing
To prevent the growth of bacteria in the unit, a flush cycle is implemented to replace the content of the water
reservoir with fresh water. The flushing is carried out at an adjustable time interval.
The production of mist is interrupted during the flushing process. The drain valve will open and the reservoir will
be completely discharged though the water discharge (drain) connection. The inlet valve will open and flush out
any stagnant water in the water supply line. The drain valve is closed and the inlet valve is closed after the water
level inside the reservoir reaches the normal operation level. After a flush cycle the unit resumes normal
operation.
