    4. Operation and Installation Basic Requirements For basic operational requirements of the HygroMatik nozzle system, please read Section “Directions for Use”. 4.2 Sequence of Operation When the hygrostat calls for an increase in humidity, the control unit opens the pilot and vacuum valves by means of control air.

  • Page 13: Vacuum Nozzle Type Vn

    4.3 Vacuum Nozzle Type VN All water-bearing parts of the vacuum nozzle Type VN are made of stainless steel. The pilot valve supplies the nozzles with atomisation air. The vacuum valve feeds the nozzles with water. The control unit con- trols both valves via a control air line.

    4.6.1 Vacuum Valve Mode of Operation The water supply is connected to installation (2). The control air (1) from the control unit is connected to the pres- sure reduction valve (5). The control air presses the ventil plate (11) and cone (10) upwards, opening the water supply (2) Water now flows into the upper chamber.

  • Page 25: Atomisation Output

    4.8.1 Output Table The output table below indicates the atomisation output of the VN nozzles. Atomisation output depends on the water pressure set by the vacuum valve and the atomisation air pressure set by the control unit. These settings simultaneously influence droplet size (see 4.8.2).

  • Page 26: Droplet Size

    Warning: Maintain safe distances from all electrical machines, as well as sensitive units or devices, as described in Section "General Installation Instructions". 4.8.2 Droplet Size Droplet size depends on the atomisation air pressure and the water pressure set by the vacuum valve. The higher the atomisation air pressure in the control unit, and the higher the water pressure in the vacuum valve, the finer the atomisation.
