Nalco TRAC100 is a liquid corrosion and film inhibitor for the use in closed
cooling systems. Optionally with TRASAR technology: it monitors, shows and
dosages the product automatically to its target concentration and continuous‐
ly protects the system. Nalco TRAC100 is a complete inhibitor protecting fer‐
rous metal, copper alloys and aluminum against corrosion. Nalco TRAC100
is free of nitrite and minimizes the requirements for micro-biological control.
Nalco 7330 is a non-oxidizing broad band biocide and suitable for application
in closed cooling circuit systems.
Nalco 73199 is an organic corrosion inhibitor supporting a fast own protection
layer and covering protection layer for non-ferrous metals.
The above additives are part of the preventive water treatment program by
Nalco. It comprises not only the chemicals but also test methods, service and
equipment. All these are made available to the user of the products.

Tab. 9-11: Water quality of additional water
The water treatment program is a specification for the user and describes the
necessary minimum.
Additional equipment, tests and service must be coordinated with Nalco to
reach optimum performance and system protection for the cooling system.
