Excellent protection against corrosion, erosion, and cavitation, for aluminium water pumps.
Heat transfer remains optimised: wholly organic additives allow avoiding any formation of deposits and left surfaces clean.
The additives in COOLELF AUTO SUPRA -26° give to the coolant:
Chemical neutrality (pH 7-8.5).
A reserve of alkalinity to neutralise the acids resulting from the combustion gases.
Resistance to foaming (mainly instability of the foam that might form).
Compatibility with hard water (maximum 40°F).
No silicates, phosphates, chromates, nitrites or boron contains.
COOLELF AUTO SUPRA -26° is inert to elastomeric seals and paints.
