Chemical and Physical Treatments, what to do
Corrosion protection
The plant thoroughly rinsed must be loaded
again by making the necessary corrosion pro-
tection, using the filming FILMAx+Thermakil
®
in
ratio of 1 - 2 % and letting it circulate into the sy-
stem permanently. This product will in fact have
the capacity to create a layer of coating on the
metal parts making up the system , preserving
them from the precipitation of sludge, rust, sca-
le, algae, etc .
In order to ensure a constant and lasting cor-
rosion protection to the system, we suggest to
check regularly (at least twice a year as required
by the UNI 8065:2019) the pH value that must
always be between 8 and 9.5, while in the pre-
sence of radiators or aluminum elements and
its alloys, the pH must be according to Norm
between 7 and 8.
In case of need of an antifreeze we suggest to
add to the system antifreeze ATIGEL or ALIGEL
in concentrations not inferior to 30 %, in this way
you obtain both antifreeze and good anticorrosi-
ve protection for 3 - 5 years.
In the presence of pipes or carbon steel (iron)
radiators, we suggest, as a further guarantee
protection of the boiler and of the total plant, the
application of the magnetic filter – sludge remo-
ver MAG- NEx HP Series, installing it after the
latest radiator on the return of the boiler.

Sludge removal
In case a quick cleaning is required due to
an excessive clogging of the system and the
consequent drastic performance reduction, or
when it is not indicated to make the product
circulate with the pump or with the circulator
because of the presence of a new boiler, or
without a boiler, you need the use of the spe-
cial high-efficiency pump DISIFLUx, dosing
ANTINEx+Thermakil
®
in doubled or tripled
percentages compared to the previous condi-
tions , so in ratio of 4 - 6 % of the circulating
liquid for at least 2 - 6 hours, or some more
time until water runs clean. The same pump
will have also the loading and testing function.
Corrosion protection
In summary, as in previous cases , but wi-
thout completely draining the system, you will
perform a backwash with water, later you will
refill the protective FILMAx+Thermakil
®
or al-
ternatively the right concentration of antifree-
ze ATIGEL or ALIGEL ( at least 30 % in order
to obtain besides a good antifreeze action
also proper anticorrosive action).
Also in this case it is recommended, in the
presence of radiators in carbon steel (iron),
the installation after the last radiator on the
return in the boiler, the magnetic filter - slu-
dge remover MAG-NEx HP Seriese specially
in the presence of corrosive phenomena such
as rust scales or incoherent magnetic oxide
(Magnetite).
