Typical De-NOx Grade Emission Control System

The world class patented「De–NOx Grade – Emission Control System」is built by three major「Exhaust Treatment Units」: (1) 「SIC Silicon Carbide Soot Removal Array」is made by「Combifilter」supplied by Swedish company「Engine Control Systems Europe AB」, not only the particulate of exhaust is trapped and removed, but also the SIC DPF is regenerated automatically at site with electrical heaters, which is totally independent from the exhaust temperature and load of diesel engine. (2)「Oxidation Catalyst Odd Removal Array」is an excellent combination of 「Diesel Oxidation Catalyst」 and 「Zeolite」, where Hydrocarbon and Carbon Monoxide can be reduced and odd of diesel exhaust also be removed even at very low exhaust temperature. (3)「SCR De-NOx Reactor」is designed for NOx reduction of exhaust by integrating SCR (Selective Catalytic Recovery) technology together with special developed high performance of mixing pipe and dosing unit of reductant. The required amount of Ammonia will be generated from「Aqueous Urea Solution」for the usage of SCR process depending on the content of NOx of exhaust.

The invention patents of Taiwan and U.S.A. have granted in 2004 and 2007 respective by Trivision’s system, due to the state of art system design and excellent performance of the「De–NOx Grade–Emission Control System」. The patented system has been wildly installed onto Gensets and Dynamic UPS in the high tech. industry of Great China, not only because it’s high reliability and low maintenance cost, but also the emission of treated exhaust from the patented system complies with the regulations listed as below:

「Limits and measurement methods for exhaust pollutants from diesel engines of non-road mobile machinery（Ⅰ）（Ⅱ）( GB 20891)」of China in 2007 and 2009.

「Tier 4 standards」for non-road engine of U.S.A. in 2011 and Gensets engine of U.S.A. in 2015.「Stage 4 standards」for non-road engine of Europe in 2015.
