Excellent protection against corrosion, erosion, and cavitation, for aluminium water pumps.

Heat transfer remains optimised: fully organic additives allow avoiding any formation of deposits and leave surfaces clean.

The additives 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).

GLACELF AUTO SUPRA contains no silicates, phosphates, chromates, nitrites or boron.

The coolant fluids obtained by diluting GLACELF AUTO SUPRA are also inert to elastomeric seals and paints.
