▍Product Introduction


The DOC+CDPF technology (Continuously Regenerating Technology DPF) independently developed by Leelool Purification is a continuously usable online catalytic oxidation regeneration technology. Compared with traditional regenerative DPF technology, its advantages lie in the continuous capture and automatic regeneration of exhaust particulate matter, smooth exhaust emissions, no increase in exhaust system back pressure, and no impact on engine power. The entire system is safe, reliable, and technically reasonable, with no bypass settings and independent operation. Through continuous exhaust oxidation-reduction reactions, it constitutes a perfect regenerative particulate filter - DOC+CDPF system. This product has been widely used in emission reduction for ships and non-road mobile sources.
