How Retrofit Emission Control Devices (RECD) Help Reduce Pollution from DG Sets

Introduction
Details
Diesel Generators (DG sets) are widely used across industries, commercial spaces, and residential complexes to provide backup power. However, these generators are also significant contributors to air pollution due to their emissions of harmful pollutants such as particulate matter (PM), nitrogen oxides (NOx), and carbon monoxide (CO). To combat this issue,Retrofit Emission Control Devices (RECDs) have emerged as an effective solution, helping reduce the environmental impact of DG sets.
Understanding RECD for DG Sets
A Retrofit Emission Control Device (RECD) is an advanced filtration system designed to minimize harmful emissions from diesel generators. These devices are installed onto existing DG sets, making them a cost-effective alternative to replacing non-compliant generators. The technology used in RECDs ensures that DG sets adhere to the latest Central Pollution Control Board (CPCB) emission norms, thereby promoting cleaner air.
How RECDs Reduce Pollution
1. Capturing Particulate Matter (PM)
Diesel engines emit fine particulate matter that can penetrate deep into the lungs and cause respiratory illnesses. RECDs use electrostatic precipitation, ceramic filters, or diesel oxidation catalysts to capture and filter PM before it is released into the atmosphere.
2. Reducing Nitrogen Oxides (NOx)
NOx emissions contribute to smog formation and acid rain. Some RECDs integrate Selective Catalytic Reduction (SCR) technology, which converts NOx into harmless nitrogen and water vapor, reducing the environmental impact significantly.
3. Controlling Carbon Monoxide (CO) and Hydrocarbons (HC)
RECDs use oxidation catalysts to break down CO and unburned hydrocarbons into less harmful carbon dioxide (CO2) and water vapor. This helps improve air quality and reduces health hazards related to toxic emissions.
Government Regulations and CPCB Compliance
The Central Pollution Control Board (CPCB) has set strict emission norms under its graded response action plan (GRAP) to control pollution, especially in cities like Delhi NCR. CPCB mandates that all DG sets above 125 kVA must either be phased out or upgraded with approved RECDs. Compliance with these norms is essential for businesses to avoid penalties and continue operating their DG sets.
Key CPCB Regulations for DG Sets:
Diesel generators must meet emission norms specified in CPCB-II guidelines.
Installation of RECDs is mandatory in many industrial zones and residential areas.
Non-compliance may result in fines or operational restrictions.
Advantages of Using RECDs for DG Sets
✅ Cost-Effective Compliance: Helps businesses meet CPCB emission norms without replacing existing generators.
✅ Improved Air Quality: Significant reduction in PM, NOx, CO, and HC emissions.
✅ Sustainability: Supports green energy initiatives and reduces the carbon footprint.
✅ Long-Term Savings: Enhances fuel efficiency and reduces maintenance costs of DG sets.
✅ Regulatory Approval: CPCB-approved RECDs ensure businesses remain compliant with environmental laws.
Conclusion
With rising environmental concerns and stringent government regulations, adopting RECD for DG sets is no longer an option but a necessity. These devices provide a practical and cost-effective way to reduce pollution, ensuring cleaner air and regulatory compliance. If you operate DG sets, installing a CPCB-approved RECD is the best step toward sustainability and legal compliance.
