Opticool Antifreeze Red is an ethylene glycol based engine coolant concentrate, which uses Organic Acid Inhibitor Technology (OAT) and is free from nitrites, amines, phosphates, borates and silicates.
It is BTC Classification Type 4E. Fleet trials have shown that when used at the correct concentration coolants based on Organic Acid Inhibitor Technology continue to provide effective corrosion protection for up to 250,000 km for passenger cars and 500,000km in commercial vehicles.
It is recommended that the coolant is replaced when the above mileages have been reached or after 5 years which ever is the sooner. Unlike traditional coolants which employ inorganic inhibitors, Opticool Antifreeze Red has excellent hard water stability and very low inhibitor depletion rates. Opticool Antifreeze Red is suitable for all year round usage in automotive and commercial petrol and diesel engines and certain industrial applications.
