Retrofit Aftertreatment System RECD

Why Purchase Cummins Retrofit Aftertreatment System (RECD)?



Diesel Generators used for power generation emit harmful gasses, Hydrocarbon (HC), Particulate matter (PM), and Carbon Mono Oxide (CO), that are harmful for the environment.

To control air pollution, government is implementing emission norms which mandates gensets to meet limits specified by government.

Cummins RAS device can be installed on Diesel Genset as an effective solution to reduce harmful gases from the exhaust gas of a DG. Cummins RAS has a particulate mass emission reduction efficiency, which qualifies it to be certified as meeting the classification class as defined in this regulation.
