SCR Exchange

Following the introduction of the Euro 4 and Euro 5 on-road emission standards in 2006 through 2008, engine manufacturers began installing SCR exhaust systems in commercial vehicles and vans. Today, some of those exhaust systems have already been in service for nearly 10 years and have reached the end of their service life. These systems need to be replaced, not only to ensure the functionality of the exhaust system but also to retain the vehicle’s permit for road use.


With SCR Exchange, the TwintecBaumot Group offers the right replacement applications for the most common truck systems. In proven quality and equipped with the latest technology, these systems satisfy high original equipment quality standards, thereby providing a comparable OEM replacement program at significantly lower prices.
