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 protection
iron 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 suiteable for applica‐
tion 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.
For additional information and order placement, please contact Fa. Nalco.
Observe the specified temperature range and take into account the existing
ambient temperature when setting the coolant inlet temperature.
The coolant inlet temperature must be set in a temperature range
of +10 ... +40 °C and is limited to no more than 5 °C under the
existing ambient temperature to avoid condensation.
Allowed coolant temperature setting range:
Ambient temperature:
Coolant inlet temperature to be set:
The maximum coolant inlet pressure of 6 bar shall be applicable to all MSK
motors. For motors manufactured before 2010-01-01 FD 10W01 the inlet
pressure must be limited to 3 bar.
Please observe that additional screw connections or junctions in the cooling
circuit can have an influence on the flow and supply pressure of the cooling
medium. The pressure drop Δp
technical data.
Monitoring systems for flow rate, pressure and temperature
should be installed within the cooling circuit.
