4.8 Spraying line
The spraying line is made of Ø 25 mm stain-
less steel pipe. The nozzle control has been
designed as pneumatic single nozzle control for
all versions. Section separation is achieved by
combining the control of several nozzle bodies.
The spray line can be fitted with single or multiple
nozzle bodies.

4.8.1 Circulation system
Due to the permanent circulation of the biocata-
lytic solution through the complete folding boom
while the sprayer is switched off, spraying fluid
is permanently applied to the nozzle.
When switching on individual sections or the
entire spraying line for the first time, the biocata -
lytic solution is directly and well mixed available.
This circulation successfully prevents the forma-
tion of deposits and blockage.
4.8.2 Cleaning nozzle tube and
nozzles
The spraying line is cleaned by the circulation
system. The suction side of the sprayer is set
to fresh water for this purpose. The nozzle line
is flushed with clean water.
Switching on the nozzles for about 3 seconds is
sufficient to clean them.
