What is RECD? 10 Powerful Facts About Retrofit Emission Control Devices for DG Sets You Can’t Ignore
Why Emission Control Matters in Today’s World
In a world facing rising air pollution and stricter emission regulations, DG (Diesel Generator) set operators are under increasing pressure to comply with eco-friendly norms. Enter RECD—Retrofit Emission Control Devices—an innovative, CPCB-certified solution designed to control diesel emissions directly at the source. Whether you’re a factory owner, real estate developer, or energy consultant, understanding RECD could be your next big compliance upgrade.
In this guide, we’ll break down what RECD is, how it works, why it matters, and how it aligns with India’s emissions roadmap
What is RECD (Retrofit Emission Control Device)
RECD (Retrofit Emission Control Device) is an advanced pollution control technology installed on the exhaust of DG sets to reduce harmful emissions like particulate matter (PM), hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx).
📌 Definition: A CPCB-approved RECD is a retrofitted after-treatment device that brings non-compliant diesel generators into conformity with air quality standards.
RECDs are mounted onto DG set exhaust outlets and use a filtration mechanism such as:
Diesel Particulate Filter (DPF)
Catalytic Converters
Ceramic Honeycomb Structures
These mechanisms trap and neutralize pollutants before they are released into the atmosphere.
✅ No engine modifications required.
✅ Plug-and-play with low maintenance.
✔️ CPCB Compliance
Avoid shutdowns and penalties under National Green Tribunal (NGT) regulations.🌍 Reduced Air Pollution
Up to 99.21% reduction in PM and soot emissions.💼 Increased Asset Life
Reduces engine stress and enhances equipment longevity.📉 Reduced Maintenance Costs
Cleaner emissions = less carbon build-up = less servicing.🏭 Industry-Wide Compatibility
Suitable for DG sets ranging from 40 kVA to 1000+ kVA.💚 Boosts ESG Goals

Frequently Asked Questions
Q1. Is RECD mandatory?
Yes, CPCB has made it compulsory for DG sets to be fitted with emission control solutions.Q2. How long does it last?
With proper maintenance, most RECD devices last 10+ years.Q3. Can RECD affect generator performance?
Not at all. Certified RECDs ensure zero back pressure
