Penrite 7-Year Blue Coolant & Anti-Freeze Premix is an Ethylene-Glycol based Coolant with advanced OAT (Organic Additive Technology) based inhibitor that is Silicate, Phosphate, Amine, Borate and Nitrite free. The extended long life formulation prevents rust, corrosion, cavitation and degredation of the cooling system.
Penrite 7-Year Coolant Premix is suitable for the cooling systems of petrol, LPG, light and heavy duty diesel and industrial engine where OAT type anti-freeze/anti-boil and anti-corrosion properties are required.
Passenger cars, 4×4’s, motorcycles, light and heavy duty commercial vehicles, construction and agricultural equipment.
Suitable for Classic and Modern vehicles, but not for Vintage cars as the OAT chemistry has been found to be damaging in older vehicles.
This coolant provides long term protection against rust and corrosion for all material used in the engine and in cooling systems. It protects Cast Iron, Aluminium, Copper and Solder Alloys as well as Hoses, Seals and Plastics which may be used in the cooling system.
It is particularly effective in all Cast Aluminium engines that are under load or used in extreme hot and cold climates.
