Top 5 Best RECD in India for DG Set Emission Compliance (2025 Edition)

Why RECD is Crucial for DG Set Emission Control
As diesel generators continue to power industries, apartments, hospitals, and offices across India, they also contribute significantly to Particulate Matter (PM) and Nitrogen Oxide (NOx) emissions.
To combat this, the Central Pollution Control Board (CPCB) mandates the use of RECD (Retrofit Emission Control Devices) on DG sets ranging from 40 kVA to 1000 kVA.
If you’re looking for the best RECD in India, here’s a curated list of the top-performing, CPCB-approved, and ICAT/ARAI-certified devices in 2025.
