PUREBLUE™ AdBlue® is an aqueous urea solution, DEF (Diesel Exhaust Fluid), 32.5% in weight, mixed with demineralised water for use in selected catalyst reduction systems.

It is a clear solution that is non-toxic, 100% biodegradable and safe to handle.

PUREBLUE™ AdBlue® is a reduction agent for oxides of nitrogen (NOx), required by SCR (Selective Catalytic Reduction) technology in diesel vehicles.

SCR (Selective Catalytic Reduction) systems require a continuous provision of a solution of Urea at 32.5% in order to operate correctly. SCR technology has been developed to fulfil the requirements of Euro 4 and Euro 5 emissions standards.
