Nett's BlueMAX™ SCR system, is a reliable, cost-effective technology designed to control nitrogen oxides (NOx) emissions from medium and heavy-duty diesel engines in on-road, nonroad and stationary applications. <br />The BlueMAX™ SCR system is a retrofit solution, that offers superior NOx reduction capabilities. Our SCR system doesn’t change or alter the design or operation of your vehicle. <br />Using urea to assist in the catalytic process, the BlueMAX™ SCR, is an exhaust after treatment system that converts harmful NOx into harmless N2 gas and H20. Our selective catalytic SCR system delivers near-zero emissions of nitrogen oxides (NOx). The urea solution is carried in an onboard tank and injected upstream of the SCR catalyst. <br />Each BlueMAX™ SCR system is custom designed for each intended application to provide optimum performance. As an additional option, our BlueMAX™ SCR system can also include either an active regeneration diesel particulate filter, or a passive catalyzed diesel particulate filter. Passive filters are generally used on engines that operate under heavy loads, with active filters being used on engines which have a lighter duty cycle. <br /><br />BlueMAX PLUS™ SCR <br />A selective catalytic reduction SCR and DPF system (NOx + PM) <br /><br />The BlueMAX PLUS™ selective catalytic reduction SCR system combines BlueMAX™ SCR technology with a passive diesel particulate filter for combined NOx and PM control of medium to heavy-duty diesel engines with higher exhaust gas temperatures. The BlueMAX PLUS™ SCR relies on heat from exhaust gases to regenerate the trapped particulates. The BlueMAX PLUS™ system includes the SCR catalytic converter, the computerized urea dosing system (UDS), the urea tank and the diesel particulate filter.
