Technology leadership

With the BNOx system, the Baumot Group offers a retrofit solution that lowers nitrogen oxides by more than 90% under real conditions (RDE). The emission values it achieves under real conditions in retrofitted vehicles of pollution class EURO IV and higher are better than those of the current EURO VI category. Thanks to its compact design, it can be used across the board for both on-road and off-road applications.

Through independent tests, such as the ADAC1 and the DUH2, the effectiveness of the system has already been proven several times.
