DEMKOR 61: Prevents corrosion in an extended pH range
The current technical water value guidelines for the protection of the various metals contain a conflict between the desired pH values for hybrid systems (which consist of aluminium as well as steel and non-ferrous metals). Despite contradictory technical guidelines, these hybrid systems are the rule today, not the exception.
What use is the best protection for your aluminium heat exchanger if the other components of the piping system are made of steel and other non-ferrous metals and these are attacked or even destroyed by corrosion due to incompatible pH values?
The use of our tannin-based product DEMKOR 61 enables an overlapping of the pH value ranges at pH 8.0 to pH 9.0 with a good corrosion protection effect on all contained components including the aluminium heat exchangers and the piping system made of steel and non-ferrous metals.
With 40 years of experience in steam boiler plants, district heating networks and hot water plants, KORN has an extraordinary application knowledge which we put at the service of our customers with pleasure and passion.
