Gentech and Mitsui to supply combined SCR sensors

Mitsui Mining and Smelting and Gentech International have reached an agreement to supply SCR combined sensors, used in the Adblue tanks of diesel-powered vehicles with SCR emissions systems.

Mitsui's urea quality sensor, named Senfoa, has been integrated into Gentech's level sensor, which is mounted in the top of the Adblue tanks on commercial vehicles.

The relationship between Gentech and Mitsui will be advantageous to OEMs, as they will be able to buy a combined module that will handle Adblue tank quality and level requirements.

Selective catalytic reduction (SCR) is an exhaust-after-treatment method used with diesel engines to reduce NOx emissions.

The SCR system relies on the injection of an aqueous urea solution into the exhaust stream in order to facilitate the reduction of NOx emissions.

This aqueous urea solution (32.5 per cent urea and 67.5 per cent demineralised water by weight) is called diesel exhaust fluid (DEF) in North America and Adblue in other parts of the world.

The quality of DEF and Adblue is strictly defined by ISO and Din standards.
