5.4.1 Treatment effect
The water treatment device works
completely automatically. The treatment
effect reached depends on actual flow rate.
A flow-controlled water meter is integrated in
the unit intake.
As water flows through the unit, a magnet in
the water meter sends impulses to a hall
sensor in the electronics enabling the
system to calculate flow rate and regulate
the treatment current to actual levels
required offering optimal treatment for
actual flow rates & water quality levels.
As soon as water flows, the water treatment
is indicated by the flashing of green LED 1
(see fig. 12).
5.4.2 Lime protection function
During treatment, the system sets free
minute lime crystals (seed crystals) which
attract lime dissolved in the water. The unit
itself contains a titanium anode and a stain-
less steel brush which acts as a cathode. As
soon as water flows through the unit, a
current is passed between these two
attracting dissolved lime to settle on the
brush in the form of calcium carbonate crys-
tals. During cleaning, the brush rotates
shedding these micro-crystals. Larger crys-
tals and particles sink to the unit floor during
cleaning and are flushed out of the unit.
The lime particles can be seen in the
flushing water as very fine “sand”. The
micro-crystals released during cleaning
remain in the water supply and act as seed
crystals attracting further dissolved lime to
precipitate. Especially in warm water appli-
cations, the growth of these crystals
appears in the form of a gradual clouding in
the water supply. In cold water applications
this growth is much slower. In both applica-
tions, however, these micro-crystals remain
light enough to remain in suspension and
are passed through the system with the
regular water flow.
As calcium in the incoming water supply is
now bound in the incoming water supply in
the form of micro-crystals, it is still present,
but cannot precipitate out onto other
surfaces (pipes, heating elements, etc.) and
these will no longer suffer from build-up or
fur.
The flow-control water meter located in the
unit inflow can monitor flow rates as low as
1.5 ltr./min. and, thanks to well coordinated
electronic systems, offers optimal water
treatment from low flow rates up to the
nominal flow level adapting impulse genera-
tion to suit actual water quality conditions.
