Model UA2 - Urea Dosing Systems



Cummins Emission Solutions airless and air-assisted urea dosing systems enable reduction of oxides of nitrogen (NOx) emissions for selective catalytic reduction (SCR). Our knowledge and experience with urea-based systems and components complement any SCR solution. Understanding the complexity of the commercial vehicles and equipment allow us to offer a more integrated approach while delivering optimal emissions performance.

Our urea dosing systems use proprietary electronic control technology to measure pre-aftertreatment NOx levels. Based on the NOx level sensor reading, the controls system commands the urea doser to inject the reductant into the exhaust stream, which ultimately chemically reduces NOx levels output post-aftertreatment.
