A new solution provides retrofit emission control devices for diesel generators that capture up to 90% of particulate matter, converting it into usable ink. This reduces air pollution and has received CPCB Type Approval in India. To combat high air pollution from diesel generator (DG) emissions in urban areas, an innovative solution develops retrofit emission control devices (RECDs) like Chakr Shield. These devices capture particulate matter from DG exhausts, reducing PM emissions by up to 90%, converting the harmful soot into usable ink, and extending the DG’s lifespan. This solution is the first in India to receive CPCB Type Approval for RECDs and has garnered global recognition for its environmental impact.
