The dry-type black smoke purifier for generator set exhaust gas, independently developed by Guangdong Green Valley Environmental Technology Co., Ltd., adopts an integrated combination of innovative materials and advanced craftsmanship. It achieves high-efficiency purification through a parallel structure of multiple metal DPF carriers, and innovatively applies a snap-fit modular design. With precise performance calibration and full-scenario adaptability, it meets the requirements of the Tier 4 Final standard, providing an efficient and reliable exhaust gas purification solution for various generator sets to enter the North American market.
Green Valley Environmental uses imported 316L alloy wire from France to manufacture metal felt filter carriers, which are coated with precious metal catalysts. These carriers feature high temperature resistance, corrosion resistance and excellent air permeability, ensuring stable operation in the complex exhaust gas environment of generator sets. Boasting stable operation and convenient maintenance, the dry-type black smoke purifier complies with the North American Tier 4 Final standard, which sets differentiated test procedures and emission limits for generator set engines of different power levels (19–56 kW, 56–560 kW, and above 560 kW). In addition to holding UL certification, the dry-type black smoke purifier for generator set exhaust gas of Green Valley Environmental can be adapted to mainstream domestic and foreign brand generator sets with a displacement range of 10L–100L and a power range of 50KW–5000KW through modular and customized design, covering the main application scenarios of the Tier 4 Final standard.
In the future, Green Valley Environmental will continue to deepen its efforts in the field of generator set exhaust gas treatment, expand its adaptability to a wider power range, contribute Chinese strength to the global environmental protection cause and the achievement of the “dual carbon” goals, and enable more generator sets to unleash green power generation capacity on the basis of compliant emissions.
