In addition, when the set point is above the humidity level in the chamber, the air valve
opens which applies air pressure to the nozzle(s). This air pressure results in the
opening of the water valve internal to the nozzle(s) and the atomization process is
started.
As the humidity level in the chamber reaches the set point, the control system will start
controlling the air valve to take control of the humidity level in the chamber. The valve
will remove air pressure from the nozzle(s) for longer and longer periods to control the
humidity level within the set point parameters.
If the humidity function is turned o
ff
, Events 3 and 4, then the system reverts back to
the condition described above and the air and water lines are ported to exhaust
condition. At this point the nozzle(s) can be safely removed from the chamber once
they have cooled o
ff
.
Maintenance
The humidification nozzle(s) do not require routine maintenance. The water supplied to
them should be free of debris and suspended solids, and it is recommended that a 10
micron filter be installed between the chamber and the water supply. This will prevent
premature plugging of the nozzle tip.
