Our ecoNOxt™ system is retrofitted to the vehicle’s emission system to treat the emissions of the vehicle so that it can reduce the harmful NOx and other pollutants.
ecoNOxt™ is a selective catalytic reduction (SCR) system and can be specified with or without our ecotrap diesel particulate filter (DPF) technology to control NOx / NO2 and NH3 slip.
– Industry leading warranty and after sales support.
– Dual NOx sensors and on board emissions data log as standard at no extra cost.
– Direct replacement OE system and manufacturing.
– Best available fleet maintenance risks and whole-life costs with the lowest possible lead time.
The SCR catalyst reduces NOx (NO/NO2) by injecting and diffusing AdBlue (an aqueous dilution of Urea) into the exhaust stream upfront of the catalysts then converting the AdBlue (Urea) into gaseous ammonia (NH3) within the exhaust.
The gaseous ammonia reacts across the SCR catalysts removing some of the oxygen content to leave harmless Nitrogen (N2) and Water Vapour. When integrated with our ecotrap DPF the system also reduces carbon monoxide (CO), Hydrocarbons (HC), and Particulate Matter (PM) to Euro 6 PM levels. The sensor based AdBblue injection system is managed by an Electronic Control Unit (ECU) which controls the amount of AdBlue being dosed by obtaining feedback from dual NOx sensors positioned Upstream and Downstream of the SCR catalysts.
An Ammonia Slip Catalyst Coating is also used at the rear section of the catalysts to prevent any excess ammonia being released from the exhaust. The system can be specified with the optional features of limp home and remote access to emissions reduction and system performance data, in line with emerging Ultra Low and Clean Air Zone market demands.
