RECD SERVICES
Retrofit Emission Control Device (RECD)
A Retrofit Emission Control Device (RECD) is an advanced emission after-treatment system designed to significantly reduce harmful exhaust pollutants from diesel generator (DG) sets. It enables existing generators to meet the latest CPCB emission compliance requirements, without replacing the entire DG set.
RECD technology helps reduce key pollutants such as:
- Particulate Matter (PM)
- Hydrocarbons (HC)
- Carbon Monoxide (CO)
- Nitrogen Oxides (NOx)
The Smart Alternative to Generator Replacement
Replacing a working DG set can be costly and timeconsuming. RECD provides a responsible and cost-effective alternative by upgrading emission performance while keeping the existing generator operational.With Greaves Cotton Limited-approved RECD solutions, businesses can achieve CPCB compliance, improve sustainability performance, and continue operations smoothly.

How RECD Works
In a diesel generator, exhaust gases contain harmful emissions that must be treated before release into the environment. The exhaust stream is routed into the RECD system through End-In or Side-In configurations, depending on site and DG layout.
Inside the RECD system, the exhaust passes through:
1. Fuel Oxidation Catalyst (FOC)Helps reduce HC and CO by oxidizing unburnt hydrocarbons and carbon monoxide into safer compounds
2. Catalytic Soot Trap (CST)Captures and reduces Particulate Matter (PM) and soot particles effectively.
Continuous Passive Regeneration (CPR)
To maintain performance, the trapped particles regenerate automatically through Continuous Passive Regeneration (CPR). This ensures:
- Consistent filtration efficiency
- Reduced blockage risk
- Long-term reliability
- Minimal manual intervention
Why RECD is Essential for CPCB I & II DG Sets
With tightening environmental regulations, DG sets that fall under CPCB I & II categories face increasing compliance challenges—especially in metro cities, industrial zones, and sensitive areas.
RECD offers a practical solution by enabling:
- Upgrade to CPCB IV+ compliance
- Reduced environmental impact
- Avoidance of penalties and operational disruptions
- Extension of DG set life without major capital expenditure
The Smart Alternative to Generator Replacement
Replacing a working DG set can be costly and time-consuming. RECD provides a responsible and cost-effective alternative by upgrading emission performance while keeping the existing generator operational.
