Helamin is a
boiler feedwater treatment based on
amines and
polyamines. Helamin is a registered trademark of Helamin Technology Holding SA, Switzerland. Patents have been obtained for Helamin products, and in 2016, the following patents exist: EP1045045, JP4663046, HK1032080, BR9903614. Chemically, most of the Helamin types are stated by the manufacturer to be a "mixture of
polyamines and
polycarboxylates in aqueous solution", but some also utilize volatile amines,
ammonia,
polyelectrolytes, organic polymers, and
scavengers of dissolved oxygen. In contrast to the conventional method of the water treatment, its action is based on a preventive protection of the surfaces. Helamin forms a film (i.e., is one of numerous available "filming amines"), which prevents corrosion and
fouling on the water-side walls in
steam boilers and piping systems, due to the affinity of Helamin to metal and oxide surfaces.
Crystals which form in the presence of Helamine are isolated, so that they do not tend to group themselves. Thus deposit consolidation is inhibited. Already existing
oxide surface deposits are gradually removed. In the boiler, a fine, liquid mud, which is easier to remove from the boiler walls, develops. Helamin does not significantly decompose even at high
temperature and
pressure employed in the modern sub-critical -water power-plant boilers. Helamin treatment can be successfully employed in
steam generators, warm and hot water piping systems,
superheaters, as well as cooling circuits to mitigate some of the difficult problems of the corrosion and fouling. However, cation
conductivity of water tends to increase with the use of Helamin. ==Fineamin==
