Circulation
With
the
nozzles
switched
off,
the
circulation
valve
(43)
is in position
(b)
, so that the wash
flows
through
the
circulatio
n
system
back
into
the
spraying mixture container.
This
prevents
the formation of deposits. Wash is immediately available at the nozzles when switching on. Due
to the permanent
circulation
of the biocata
-
lytic solut
ion through the complete spraying line,
wash is constantly present at all nozzles while the nozzles are switched off. Even 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 forma
-
tion of deposits and blockage.
