Pickling and passivation
of a new thermal system
(0 - 6 months)
1 - 4 hours
In case of a new or recently installed (3 - 6 months)
system, before loading the circuit it is necessary
to perform a good wash until the water is perfectly
clean or better pickling, this means the removal of
metal oxides and processing waste (oils, shavings,
hemp residues, bad quality pastes, etc.).
We remember you that new does not mean clean!
Pickling
Make a pickling adding 2 % FERRONEx respect
to the total circulating liquid, and let it work for at
least 3 - 5 hours inside the circuit .
Once finished, drain the system and perform an
abundant backwash with water till this comes out
clean, then in order to get a good corrosion pro-
tection, add the additive FILMAx+Thermakil
®
as
in the previous case is suggested, or in case of use
of antifreeze add with ATIGEL in a concentration
not inferior to 30 % .

In the presence of various types
of sludge inside the plant, the
best method is the use of a slud-
ge removal coupled to an anticor-
rosion treatment with or without
antifreeze.
Facot therefore suggests the use
of ANTINEx+Thermakil
®
, a dissolution healing
mud , disintegrating for sludge, algae, mud and li-
mestone for thermal heating systems .
Suitable for all types of plants, multimetallic or pla-
stic ones, ANTINEx+Thermakil
®
is an anti-corro-
sion product that brings the limestone and the de-
posits contained into the systems in suspension.
Sludge removal
First you will need to drain the system from the
circulating liquid, in order to immediately eliminate
most of the inconsistencies, and check the quantity
of water present in order to successfully perform
the subsequent dilutions.
At this point you will have to use ANTINEx in ratio
of 2 - 3 % of the circulating liquid into the system
and make the boiler circulate at operating speed
for at least 15 - 20 days , depending on the state of
the plant , taking care to protect the boiler with the
special filter WL-FILMAT-RAH HOT equipped with
purging.
Once the healing treatment finished, you will proce-
ed to drain all the liquid and make a backwashing
with water until it runs clear and clean.
