General guidelines regarding
maintenance
Plate Sheet material
Also stainless steel can corrode. Chlorine ions are
hazardous.
Avoid cooling brines containing chloride salts as
NaCI and, most harmful, CaCI
Note!
Rinse well!
Note!
Under no circumstances should Hydrochlo-
ric acid be used with stainless steel plates.
Water of more than 300 ppm Cl ions may
not be used for preparation of cleaning
solutions.
Chlorine as a growth inhibitor
Note!
Chlorine, commonly used as growth inhibi-
tor in cooling water systems, reduces the
corrosion resistance of stainless steels.
Chlorine weakens the protection layer of
these steels making them more susceptible
to corrosion attacks than they otherwise
should be. It is a matter of time of exposure
and concentration.
In every case where chlorination of AlfaNova heat
exchanger cannot be avoided, your local representa-
tive must be consulted.
