10. Hygiene
10.1 Ensuring hygiene (VDI 6022)
The regulations require that only inert materials must be used
and biocides should only be used as a last option.
Prior to humidification the supply air is to be purified using a
Class F7 filter.
A metal filter made of mesh wire is used as a droplet separator.
The droplet separators can, as far as is necessary, be easily
cleaned and reused. Addition of a biocide is not required.
All components must be easily accessible to perform a cleaning
in accordance with VDI6022.
In order to carry out a visual inspection according to VDI 6022
sufficiently large windows / removable panels have to be pro-
vided in the area of the droplet separators and the vortex mod-
ules.
10.2 Automatic flushing
If the HygroMatik nozzle system LPS is in „stand by mode” and
there is no demand for work for 24 hours the system will periodi-
cally run (every 24h) flush cycles.
Hereby the growth of bacteria in standing water is obviated.
During flushing the inlet water solenoid valve and the flushing
valve are simultaneously open. Thus the water in the pump sta-
tion is being exchanged and directly led into the drain without
reaching the humidification chamber.
