APPLICATION:
Protection all year round: COOLELF AUTO SUPRA -37° ensures maximum protection against freezing, until -37°
Ready to use product: COOLELF AUTO SUPRA -37° is ready for to use, as a mix with demineralized water.
Multi-material compatibility: COOLELF AUTO SUPRA -37° can be used for cast iron as well as aluminum engines, and in engine radiators in aluminum or copper alloy.
Lifetime: COOLELF AUTO SUPRA -37° is inert to elastomeric seals and paints. Recommended oil change interval:
- 500 000 km/4 years when used in trucks
- 250 000 km/5 years when used in cars
CUSTOMER BENEFITS:
Very long-term protection against metals corosion: Organic technology ensures a long-term action to offer maximum protection against any type of corrosion, erosion and cavitation, even at high temperatures.
Maximum heat tranfer: The organic additives in COOLELF AUTO SUPRA -37° give to the coolant
- Chemical neutrality (pH7-8,5),
- A reserve of alkalinity to neutralize the acids resulting from the combustion gases,
- Resistance to foaming,
- Compatibility with hard water (maximum 40°F).
Avoids formation of deposits (no risk of limescale) and leaves surfaces clean.
HSE
All antifreezes and coolants based upon monoethylene glycol are regarded as special industrial wastes and must be disposed of in approved centers for environmental reasons
