Organic technology ensures a long-term action to offer maximum protection against any type of corrosion, erosion and cavitation, even at high temperatures.The organic additives in COOLELF FR CP 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.- Compatibility with hard water (maximum 40°F).Avoids formation of deposits (no risk of limescale) and leaves surfaces clean.
