The nitrite content of nitrite-based cooling water additives usually decreases during use. If the
nitrite content decreases below the given limits, the risk of local corrosion increases.
The nitrite content can be given as sodium nitrite (NaNO
2
) or as nitrite (NO
2
).
1 mg/l as NO
2
equals to 1.5 mg/l as NaNO
2
.
Nitrite-based cooling water additives do not give good protection against corrosion for aluminium
and its alloys. For these materials WinGD recommends not to use nitrite-based cooling water
additives.
