Marine DEF reduces smog from diesel engines by reducing Nitrogen Oxides (NOX) in the exhaust stream.
Marine DEF is not the same as automotive DEF for trucks, cars, etc. used for transportation. They cannot be used interchangeably.
Marine DEF is a blend of 40% urea and 60% water. It is non-hazardous and non-flammable.
Marine DEF is a clear liquid stored in a separate tank from the diesel fuel tank. As the engine runs, a small amount of DEF is injected into the exhaust to reduce NOX emissions.
Vaporex Marine DEF is registered with the American Petroleum Institute (API) and meets or exceeds ISO 22241 and AdBlue standards.
Vaporex DEF is packaged in convenient 330-gallon totes or can be delivered by 5000-gallon tanker loads.
