If you’re planning to install a Retrofit Emission Control Device (RECD) on your diesel generator (DG set) to meet CPCB emission norms in India, understanding the cost structure and what affects pricing is key before you get quotes from vendors.
Typical Price Range for RECD in India
The price of an RECD system can vary widely depending on DG capacity, technology, and vendor options. Here are some real price examples:
Indicative RECD Device & Kit Prices
- RECD for small DG sets (e.g., ~80 kVA): ~₹1.7 lakh (₹172,516 approx.) per unit.
- Standard industrial RECD units: ~₹2,00,000 per piece (device only).
- Mid-range RECD kits (general retrofit): ~₹2 lakh – ₹3 lakh.
- RECD for larger DG sets (e.g., ~380 kVA): ~₹6 – 7 lakh.
- Larger capacity systems (e.g., ~400 kVA): ~₹6.3 – 7.5 lakh.
- Heavy industrial or high-capacity units (e.g., 1000 kVA+) can exceed ₹15+ lakh.
Note: These prices may include the device itself but *can vary further depending on installation costs, testing, and labour. Prices shown are approximate retail / vendor listing values.
What’s Included in the RECD Cost?
When you receive a quote for an RECD, the cost can include:
- RECD device/equipment: The core hardware that treats emissions.
- Installation charges: Labour and fitting to your DG set’s exhaust line.
- Testing & calibration: Ensuring the installed RECD meets CPCB/NGT compliance standards.
- Documentation & certification support: Necessary for regulatory compliance checks.
- Warranty & support: Some vendors include service/maintenance support.
Key Factors That Affect RECD Pricing
1. DG Set Size (kVA / kW)
Larger DG sets require proportionally bigger or more complex RECD systems — meaning higher costs. Smaller units (e.g., 30 – 125 kVA) cost noticeably less than large industrial gensets (>500 kVA).
2. Technology Used
RECDs differ based on technical approach:
- Filter-based systems: Often simpler but may need periodic cleaning or replacement.
- Catalytic or advanced filterless systems: Higher upfront cost but lower maintenance and better performance.
The type of technology (e.g., Diesel Oxidation Catalysts, catalytic traps, electrostatic precipitators) significantly changes pricing.
3. Certification & Compliance
CPCB-approved and ICAT or ARAI-tested devices usually cost more because they’ve been lab-verified for emission reduction performance. Certified devices help avoid regulatory issues.
4. Installation Complexity
How easy or difficult it is to install the RECD on your particular DG set affects labour costs. Older gensets, custom exhaust arrangements, or space constraints can increase installation time and cost.
5. Additional Services
Some vendors offer:
- On-site emission testing
- Commissioning
- Post-installation support & maintenance
These services can add to the total project cost but are valuable for compliance assurance.
Operating & Ongoing Costs
While most costs are upfront, there may be ongoing maintenance charges for certain types of RECD (especially filter-based ones). Filter replacement, cleaning, and periodic performance checks add to lifecycle costs.
Takeaways
| Category | Estimated Cost (₹ INR) |
|---|---|
| Small DG set (≤ 100 kVA) | ~1.7 – 2.5 lakh+ |
| Mid-range genset RECD | ~2 – 5 lakh+ |
| Large DG set RECD (300 – 400 kVA) | ~6 – 8 lakh+ |
| Heavy industrial systems | ₹10 lakh+ |
Tips to Get Accurate Quotes
Always ask for CPCB/ICAT/ARAI certification evidence before purchase.
Clarify whether the price includes installation and compliance testing.
Compare quotes from multiple certified vendors.
Check maintenance requirements and warranty terms.
