Baumot technology will improve air quality in Berlin through retrofit of 100 diesel buses

GERMANY The BNOx retrofit system from Baumot has been selected to be retrofitted to 100 buses in Berlin. The contract was won in December 2017 following an increase in focus for retrofitting in the bus sector, says supplier, Baumot.

The BNOx is a combined SCR + DPF system upgrading old buses to a Euro VI equivalent emission standard, and the technology can also be retrofitted to EURO III, IV, V and EEV buses allowing for rapid conversion of an operator’s fleet to the latest emissions standard cost effectively.

Winfried Doelling, Managing Director for Aftertreatment in the Twintec Baumot Group, said: “This opportunity is great for us to demonstrate how the innovative Baumot technology removes Nitrogen Oxide (NOx) and particulate (PM) emissions from vehicles. NOx and PM air pollutions cause a large number of premature deaths which can be cost effectively prevented with BNOx technology. We are excited with the project, the first buses have been rolled out in Berlin already and all installations are to be completed by autumn this year.”

The BNOx solution lowers nitrogen oxides (NOx) by more than 90% under real driving conditions (RDE) and eliminates PM to virtually zero. It comprises a BNOx (ammonia) generator, which converts standard AdBlue (DEF) on board, on demand into Ammonia gas. The NH3 gas is then metered directly into the exhaust line. As a result of this operating principle, no function-critical hydrolysis in the exhaust gas stream is required.

As well as the BNOx system, Baumot are helping fleet operators manage vehicles by offering a system to monitor the exhaust aftertreatment system installed on a vehicle and the NOx reduction performance in real time, giving operators 24/7 access to tracking the vehicle and real-time information of the NOx emissions.

Baumot UK, part of the Baumot Group AG, is a leading supplier in exhaust gas aftertreatment products. These products and services are offered in OEM (original equipment), retrofit (retrofitting) and aftermarket (spare parts) markets. The sectors it operates in include on-road (buses, coaches, trucks and cars) and off-road (construction machinery, agricultural machinery or stationary equipment).
