Selective Catalytic Reduction (SCR)
| Typical Emissions Reduction Performance |
 |
Nett's BlueMAX™ SCR systems are designed to control the emissions of oxides of nitrogen (NOx) from medium and heavy-duty diesel engines in on-road, nonroad and stationary applications. The Nett BlueMAX system is a urea-SCR (Selective Catalytic Reduction) system. NOx is reduced over an SCR catalyst through chemical reactions with a reducing agent (urea). The urea solution is carried in an onboard tank and injected upstream of the SCR catalyst. BlueMAX™ systems can optionally include either an active regeneration diesel particulate filter, or a passive catalyzed diesel particulate filter. Passive filters are generally used on engines run under heavy load, with active filters used on engines which have a lighter duty cycle.
