Note 2: The nitrite content of nitrite-based cooling water additives tends to
decrease in use. The risk of local corrosion increases substantially when
nitrite content goes below the recommended limit.
As an alternative to the approved cooling water additives, the Elysator cooling water treatment
system can also be used. The Elysator protects the engine from corrosion without any chemicals. It
provides a cathodic/anodic protection to engine
’
s cooling water system by letting magnesium anodes
corrode instead of the engine itself. Raw water quality specification is the same as in connection with
cooling water additives. More information in document 4V92A1322.
The Elysator can be a sensible alternative in installations where the environmental factors are
considered important.
