The performance test for the used coolants and the design of the
liquid coolant system are generally the responsibility of the ma‐
chine manufacturer. The selected coolant additives must be com‐
patible with the materials within the cooling system, to avoid e.g.
electro-corrosion.
Observe the environmental protection and waste disposal instruc‐
tions at the place of installation when selecting the coolant addi‐
tives.

The proper chemical treatment is precondition to prevent corrosion, to main‐
tain thermal transmission, and to minimize the growth of bacteria in all parts
of the system.
In the following, the products of Nalco are exemplarily listed. Nalco makes
different additives in form of "ready-to-use cooling water" and "water treat‐
ment kits" available, depending on the size of the cooling system.
The use of the following chemicals is designed for closed cooling systems
and the following metallurgy.
●
Stainless steel, aluminum, copper and non-ferrous metals
The packaging size and the ingredients of the water treatment kit are com‐
pletely adapted to the corresponding system volume and the user may fill
them into the coolant reservoir without observing further mixing ratios.

Cooling water NALCO CCL100 Nalco CCL100 is a ready-to-use, preserved cooling water for the use in
closed cooling water systems. It is supplied directly to the closed systems
and contains all reagents in the propter treatment concentration.
Nalco CCL100 contains a corrosion inhibitor protecting iron, copper, copper
alloys and aluminum against corrosion. Nalco CCL100 is free of nitrite and
minimizes the micro-biological growth.
