With strict pollution norms in India, installing an RECD Kit for DG Set has become essential for many diesel generator owners. An RECD kit helps reduce harmful emissions, ensures legal compliance, and allows existing DG sets to operate without replacement.
This guide explains what an RECD kit is, its main components, how installation is done, and the expected cost—in clear and simple language.
What Is an RECD Kit for DG Set?
An RECD Kit (Retrofit Emission Control Device Kit) is a complete emission-control package designed to be installed on the exhaust system of an existing diesel generator.
It helps DG sets comply with emission norms prescribed by authorities like the Central Pollution Control Board (CPCB) by reducing particulate matter and harmful gases.
Simply put, an RECD kit cleans DG set exhaust smoke and makes the generator pollution-compliant.
Main Components of an RECD Kit
A standard RECD kit usually includes the following components:
1. RECD Chamber / Device Unit
- Core part of the system
- Installed on the DG set exhaust
- Traps or treats harmful emissions
2. Catalyst / Oxidation System
- Converts toxic gases into less harmful substances
- Improves emission reduction efficiency
3. Control Panel
- Monitors temperature and system performance
- Ensures safe and efficient operation
4. Sensors & Monitoring Instruments
- Temperature and pressure sensors
- Helps prevent overheating or back pressure
5. Exhaust Piping & Connectors
- Connects DG set exhaust to the RECD unit
- Designed to handle high temperatures
6. Mounting Frame & Insulation
- Provides structural support
- Heat insulation for safety
RECD Kit Installation Process
The installation of an RECD kit is usually done by trained professionals and involves these steps:
Step 1: DG Set Assessment
- DG capacity (kVA) is checked
- Exhaust layout and space availability are reviewed
Step 2: Exhaust Modification
- Existing exhaust line is modified (if required)
- RECD unit is connected to the exhaust
Step 3: Mounting & Connection
- RECD chamber is mounted securely
- Sensors and control panel are connected
Step 4: Testing & Commissioning
- System is tested for back pressure and temperature
- Emission performance is verified
Step 5: Compliance Documentation
- Installation records and test reports prepared
- Documents kept ready for pollution control inspection
Installation Time:
Usually 1–2 days, depending on DG size and site conditions.
Cost of RECD Kit for DG Set
The cost of an RECD kit depends on multiple factors:
Key Cost Factors
- DG set capacity (kVA)
- Type of technology (filter-based or filterless)
- Certification & compliance level
- Installation complexity
Indicative Price Range (India)
- Small DG sets (≤100 kVA): ₹1.5 – ₹2.5 lakh
- Medium DG sets (125–320 kVA): ₹3 – ₹6 lakh
- Large DG sets (≥400 kVA): ₹7 – ₹10 lakh or more
Prices may vary by vendor, city, and system specifications.
Benefits of Installing an RECD Kit
- Compliance with CPCB norms
- Significant reduction in smoke & particulate matter
- Avoidance of fines and DG set sealing
- Environment-friendly operation
- Extended life of existing DG sets
- No need to buy a new generator
Is RECD Kit Mandatory?
Yes. For many existing and older DG sets, installing an RECD kit is mandatory as per pollution control guidelines. Non-compliant DG sets may face penalties, legal notices, or operational restrictions.
Conclusion
An RECD Kit for DG Set is a complete and effective solution to control diesel generator emissions. With proper components, professional installation, and certified technology, an RECD kit ensures pollution compliance, cleaner air, and uninterrupted DG set operation.
For DG owners, investing in an RECD kit is not just about regulation—it’s about responsibility and sustainability.
