15.8. Recycling device
The recycling device enables the return of unused spray liquid.
To return the unused spray, the tunnel walls are provided with a
collector at the bottom, with a built-in injector.
Recycling injector:
The injector is covered with a
filter to prevent blockage.
(Fig. 23)
The return line leads from the
injector through the recycling
filter to the spray tank.
The injectors are switched on
and off via the control box.

returned from the tunnel collec-
tor can be adjusted via the re-
cycling valve on the main valve
block. (Fig. 24)

For spraying agents that tend to foam, it may be necessary to
close the valve far enough to allow suction without the inclusion
of excess air.
In the event of excessive foaming, the use of an anti-foaming
agent in the spray liquid is recommended.
