3.2.1 Dosing unit
For the fragrance dosing a hose pump is used, conveying even the smallest
dosing volumes securely, even when there are air bubbles in the suction
pipe. Rotating rollers press the dosing hose against the wall, squeezing out
the liquid in front of the rollers while sucking in new liquid at the same time.
Hose pumps are extremely reliable and particularly easy to operate.
Fragrance concentrates can be extremely corrosive. The dosing hose used
resists most of the commercially available concentrates.
ATTENTION !
The composition of the fragrance varies. This may reduce the service life of the hose.
You should therefore regularly check the fragrance pump according to the mainte-
nance plan or whenever fragrance is topped up.
3.2.2 Dosing valve (option)
The valve is a combined spring loaded non-return valve and dosing valve.
In case of a defect of the pump or the dosing pipe (broken hose, mainte-
nance works) the dosing valve avoids the penetration of steam from the
steam pipe into the dosing pipe.
In the error free operation no dosing valve is required since the pressure of
the pump is higher than the pressure in the steam pipe.
3.2.3 Console (option)
The device is supplied standard for wall Installation. The fragrance container is put on the floor.
The optional console is foreseen for an Installation at a higher level, so that the floor remains free. The fra-
grance container is put on the console. The console is available in two sizes.
