The SCRT® system is more than simply a combination of a CRT® system and an SCR system. In this integrated design, the CRT® performs two functions: it gives excellent conversion of CO, HC and PM, and it enhances the NO2 content of the gasses that pass into the SCR system. By optimising the gas mix supplied to the SCR catalysts in this way, excellent NOx conversions are also achieved.

SCRT® system performance

This chart shows the emissions reduction achieved by a SCRT® system fitted to a Euro 1 truck engine over the ESC 13-mode cycle, in comparison to the engine emissions and the emissions with a CRT® system fitted.

The performance of the SCRT® system has been demonstrated in many different applications and in long-term trials. For an example, see our report of a trial on a US Class 8 truck.

Typical applications:
Stationary Source
Truck and Bus
Non-road Mobile Machinery
