General Characteristics


Arnox 32 is made from pure urea for diesel engines with the function to reduce the emission of Greenhouse Gases (GHG) in a post combustion treatment.

Diesel engine vehicles with SCR technology (Selective Catalytic Reduction) allow the conversion of Nitrogen Oxides (NOx) into no harmless substances for the environment.

This technology meets the requirements of the Euro V standards, Euro V vehicles comes with a special tank separated from the diesel tank.

Proaire is a Profertil’s trade mark of Arnox 32.
