Our Products


BNOx System

Type: SCR System
Application: On- & OffRoad

Thanks to the successful evolution of the BNOx SCR system, the Baumot Group can offer customers its blockbuster technology in both the off-road and on-road setting, reducing nitrogen oxides under real-world conditions.

In simple terms, the BNOx SCR system essentially comprises a generator (ammonia/NH3), which meters the NH3 gas directly into the exhaust line. This generator uses the energy of the exhaust flow and of the electric catalytic converter.

DPF BAB System

Type: DPF System
Application: On- & OffRoad

Efficient exhaust aftertreatment systems are in high demand in the on-road and off-road sectors. The Baumot Group offers economical, durable and future-proof solutions suitable for everyday use in both original equipment and retrofit applications.

This system is based on a catalytic-coated cordierite monolith in combination with another coated diesel oxidation catalyst – “DOC” for short – upstream of it. The DOC’s task is to raise the concentration of NO2 molecules to the point that particulates are oxidized even at average exhaust temperatures of just 220°C. The increased number of NO2 molecules is then reduced again in the coated monolith.

DPF Flame System

Type: DPF System
Application: OffRoad

Another system is the DPF Flame. This is particularly useful at very low exhaust temperatures below 220°C. Thanks to a special burner system, the exhaust temperature can be increased to up to 350°C while the engine is idling or under partial-load. This makes it possible to regenerate the filter continuously (CRT) while reducing carbon monoxide and hydrocarbon pollutants at the same time. In engines with a displacement of less than 6 liters, the DPF Flame system raises the exhaust temperature while idling to over 600°C. That makes it possible to regenerate the particulate filter in about 20 minutes.
