Spraying line
The spraying line is made of stainless 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 spraying line can be fitted with single or
multiple nozzle bodies.
Circulation system
Due to the permanent circulation of the
biocatalytic 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
biocatalytic solution is directly and well mixed
available.
This circulation successfully prevents the
formation of deposits and blockage.

To clean the nozzles, all nozzles must be open
for approx. 3 sec.
