The ready-to-use fluid for radiator is based on ethylene-glycol for professional application. PARAFLU 11 is a safety fluid for cooling systems of cars, trucks and light-duty vehicles, tractors and excavators. This product meets the most stringent requirements even in the most severe operation conditions. PARAFLU 11, diluted with water in the proportion 50%, guarantees optimum heat removal from the engine combustion chamber and maximum protection from freezing (as low as - 40°C air temperature), from lime deposits in the radiator, from overheating in summer, in traffic jams on the highways, in the city mode (the temperature as high as + 110°C), from corrosion of metal parts used in the cooling system (cast iron, aluminum, copper), from excessive swelling of rubber and plastic parts of the cooling system.
