The type of the detergent supply is selected in de-
pendence of the installed pipe system. Here it is dis-
tinguished between single line and multiple line
systems.
Single line system: With the single line system the
detergent dosing takes place via mobile or station-
ary dosing units (injectors) at the extraction point.
This means, detergent tanks are directly connect-
ed with the injector by means of a short suction
pipe.
Multiple line system: With a multiple line system
the detergent dosing takes place via a central dos-
ing unit. The detergent is delivered to the injector
via stationary pipes. Multiple line systems are
used in places where the storage of detergent is
not permitted at the workstation (e.g. in food pro-
cessing areas).
For a central detergent supply a double dosing unit is
provided at each extraction point.
This enables the selection between the two available
detergents by beans of a lever. The dosing into the
HD system takes place via an injector.
The major advantage of the central detergent supply
is that uncontrolledly exiting detergent in the area to
be cleaned does not pose a risk.
For the piping of a central detergent supply we sug-
gest the use of a budget-friendly PVC pipe DN 10
(adherent) that is resistant against the relevant deter-
gent used.
As this pipe system is usually laid parallel to the HD
pipe system and saves costs and installation time
compared to stainless steel pipes, this variant is often
implemented.
