Cooling water
02.3.1 General
In order to prevent corrosion, scale deposits or other deposits in
closed circulating water systems, the water must be treated with
additives.
Before treatment, the water must be limpid and meet the speci-
fication found in the end of this chapter. Further, the use of an
approved cooling water additive or treatment system is mandatory.
Caution! Distilled water without additives absorbs carbon dioxide from the
air, which involves great risk of corrosion.
Sea water will cause severe corrosion and deposit formation even
if supplied to the system in small amounts.
Rain water has a high oxygen and carbon dioxide content; great
risk of corrosion; unsuitable as cooling water.
If risk of freezing occurs, please contact the engine manufacturer
for use of anti-freeze chemicals.
Fresh water generated by a reverse osmosis plant onboard often
has a high chloride content (higher than the permitted 80 mg/l)
causing corrosion.
Caution! The use of glycol in the cooling water is not recommended, if it is
not necessary. Since glycol alone does not protect the engine
against corrosion, additionally an approved cooling water additive
must always be used!I
02.3.2 Additives
As additives, use products from well-known and reliable suppliers
with vast distribution nets. Follow thoroughly the instructions of the
supplier.
Caution! The use of emulsion oils, phosphates and borates (sole) is not
accepted.
In an emergency, if compounded additives are not available,
treat the cooling water with sodium nitrite (NaNO
2
) in portions of 5
kg/m
3
. To obtain a pH value of 9, add caustic soda (NaOH), if
necessary.
Warning! Sodium nitrite is toxic.
