​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 RD 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.
