Cooling
By forcing water circulation, it is possible to maintain cooled internal housing temperatures. It helps to
verify the flow capacity needed and cooling water temperature before proceeding with the
installation. Before installation, it is also necessary to verify the environmental temperature and install
the housing at the correct distance from the heating source.
7.4.3
Air Barrier
The flange for window cleaning uses ventilation to create an air barrier on the front of the housing in
order to prevent any deposits of dust on the outer surface of the window. For proper use, it is always
advisable to filter the compressed air with a dedicated filter that is equipped with a gauge pressure
regulator. For proper installation, it is necessary to check the environmental temperature and place the
air filter group at the correct distance from the heat source.
For optimal performance of air barrier, it is recommended positioning the enclosure in
a horizontal position or decline angle. Positioning the enclosure with the air barrier
vertically may affect its performance!
Noise level emissions produced by air barrier may exceed recommend safe exposure
levels!
