Selective Catalytic Reduction (SCR)


The primary function of SCR catalyst in a diesel after-treatment systems (ATS) is to convert harmful nitrogen oxides (NOx =NO + NO2) in the exhaust gas to nitrogen and water. The SCR reaction takes place on the catalyst, in the presence of NH3 generated from AdBlue (Urea and water solution) upfront the SCR catalyst.


EPA advanced emissions regulations need above 95% NOx conversion levels and all Dinex SCR technologies achieve conversion levels well above this limit.


Dinex has a wide variety of SCR catalyst technologies which can be selected based on actual applications and ATS temperature levels. Typically, titanium-vanadium based technologies are suitable for applications, where the exhaust gas temperature is not exceeding 550 degrees C level. Cu-Zeolite and Fe-Zeolite technologies are suitable for conditions where the exhaust temperatures exceed well above 600 degrees C.


The most widely used SCR technology in advanced regulations is Cu-Zeolite based. The Dinex technology is typically characterized by high NOx conversion activity in wide temperature window, low NO2 formation, and very low NH3 oxidation, even at high temperature (optimal Urea utilization).

Dinex meets all levels of regulation


The Advanced US EPA07/10 regulations need complex after-treatment systems (ATS) to fulfill all regulatory requirements. After initial implementation in year 2007, US EPA regulations have been updated step by step over the years with primary focus on real driving emissions (RDE) and in-service conformity.


Dinex supports Heavy Duty and Medium Duty commercial vehicles with advanced catalyst coating technologies (DOC, DPF, SCR), which are among the best in class. The wide range of technologies provide the flexibility to modulate the ATS layout to the full benefit of our customers as per their duty cycle and application requirements. The catalyst technologies have been rigorously tested by major OEMs world-wide and meet the most stringent engineering targets and real driving emissions performance requirements.


With close to 30 years of experience in canning & housing as well as patented technologies for compact mixers, Dinex builds robust and flexible ATS canning to meet a variety of packaging and space requirements.
