RECD Indicative Price Guide by Generator Capacity

Indicative installed cost (device + installation + emission testing + certification) by kVA tier. Bands reflect installs across North India 2024-26. Exact quote depends on your specific exhaust routing, mounting access, and DPF tier selection.

Generator CapacityIndicative Installed CostGet Quote
5 - 25 kVARs 0.5 - 1.2 lakh
25 - 100 kVARs 1.0 - 1.8 lakh
100 - 250 kVARs 1.5 - 3.0 lakh
250 - 500 kVARs 3.0 - 5.0 lakh
500 - 1500 kVARs 5.0 - 8.0 lakh

Pricing ranges reflect market observation across our 2024-26 installs. Final quote depends on site survey, RECD brand selection (Cummins / KOEL / certified third-party), and any structural modifications needed for exhaust re-routing. All RECDs we install are CPCB-approved and ARAI/ICAT tested.

Three Honest Paths to CPCB Compliance

We do not push a single solution. Depending on your genset age, capacity, and runtime, a different path may save you the most money over 5 years.

Cheapest

RECD Retrofit

Keep your existing genset, add a CPCB-approved emission control device.

Indicative cost

Rs 0.5 - 8 lakh (kVA-dependent, see table)

Best for

100-500 kVA gensets under 10,000 running hours with healthy engine and alternator.

Pros

  • Lowest upfront cost (typically 15-30% of new genset price)
  • Keeps your existing investment working
  • Install in 1-3 days
  • ARAI/ICAT certificate provided

Trade-offs

  • Adds small fuel-efficiency penalty (~1-2%)
  • Requires periodic DPF cleaning every 250-500 hr
  • Not economical for very small (<25 kVA) or very large (>1000 kVA) units
Best long-term

New CPCB IV+ Genset

Replace with a new CPCB IV+ compliant unit (Greaves / Cummins / KOEL).

Indicative cost

Rs 1.5 lakh - 2 cr (kVA-dependent)

Best for

Gensets older than 10 years, heavy usage above 10,000 hours, or capacity changes needed.

Pros

  • 10-15% better fuel economy from latest CRDI engines
  • 5-year warranty on premium models
  • IoT-enabled remote monitoring
  • Highest resale value

Trade-offs

  • 4-8x higher upfront cost than RECD
  • 4-8 week lead time for premium kVA
  • Site re-prep may be needed for new footprint
Hybrid option

Used CPCB IV+ Buyback + Replacement

Sell your non-compliant unit, buy a 1-3 year old CPCB IV+ from our inspected inventory.

Indicative cost

Net Rs 1 - 30 lakh after buyback offset

Best for

Buyers who want compliance + warranty at 40-60% of new cost.

Pros

  • We buy your old DG (offsets new cost)
  • Inspected pre-owned units with our warranty
  • Faster than waiting for new delivery
  • Single-vendor handover

Trade-offs

  • Available stock depends on inventory at time of decision
  • Slightly higher running-cost vs brand-new (~3-5%)

We will recommend the path that genuinely saves you the most over 5 years, not the most expensive option. Send your genset details on WhatsApp for a no-obligation recommendation with rough TCO numbers.

RECD Installation Process at Alpha Diesels

4-step process. Site assessment within 48 hours. Install completes in 1-3 working days depending on genset size.

1

Site Assessment

Our engineer visits your site to evaluate genset model, exhaust routing, mounting space, and load profile. Free assessment within 48 hours.

2

RECD Kit Selection

We recommend a CPCB-approved RECD matched to your kVA, engine model, and emission baseline. Brand options: Cummins, KOEL, or certified third-party.

3

Installation

Our trained technicians install the RECD with proper exhaust routing, mounting brackets, and sensor calibration. Typical downtime: 1-3 days.

4

Emission Testing

Post-install emission test on PM, NOx, CO, HC. ARAI/ICAT-style report generated. CPCB compliance certificate handed over.

CPCB-Approved RECD Brands We Install

We only install RECDs that are CPCB-approved and ARAI/ICAT certified for the relevant emission category. Brand selection depends on your engine model and capacity.

  • Cummins RECD — preferred for Cummins-engine gensets, broad kVA coverage 30 kVA upwards.
  • KOEL (Kirloskar Oil Engines) RECD — preferred for Kirloskar-engine units.
  • Certified third-party RECDs — for Greaves, Mahindra Powerol, Ashok Leyland, and other multi-brand fleets. All vetted for CPCB type-approval validity.

Each install ships with the CPCB type-approval certificate of the specific RECD model. Sample copy available on request.

State-wise Compliance Notes

Compliance enforcement differs slightly by state. We handle paperwork with the relevant pollution control board.

  • Delhi NCR (DPCC + CAQM)

    Strictest enforcement. Pre-2014 gensets without RECD or CPCB IV+ replacement cannot legally operate. GRAP restrictions add seasonal bans during winter.

  • Rajasthan (RSPCB) — Bhiwadi, RIICO, Neemrana, Alwar

    Active inspections in RIICO industrial zones. Industrial units above 125 kVA expected to retrofit or replace.

  • Haryana (HSPCB) — Gurgaon, Faridabad, Manesar, Bawal

    Aligned with NCR norms. CAQM directions apply in the NCR districts.

  • UP (UPPCB) — Noida, Greater Noida, Ghaziabad

    NCR-aligned. ANPR enforcement infrastructure being rolled out per CAQM Direction 89.

Frequently Asked Questions

Common questions about RECD retrofit emission control

RECD (Retrofit Emission Control Device) is a bolt-on exhaust treatment system, typically a diesel particulate filter (DPF), that retrofits onto your existing generator's exhaust. It traps and burns particulate matter, bringing emissions down to CPCB IV+ compliant levels without replacing the entire genset.

RECD solutions can be fitted on most diesel generators above 125 kVA. The retrofit requires sufficient space around the exhaust system and compatible exhaust gas temperatures. Our engineers assess your specific genset to confirm compatibility before installation.

RECD retrofit typically costs 30-40% of a new CPCB IV+ generator's price. For example, retrofitting a 250 kVA genset costs approximately Rs. 2-3 lakh versus Rs. 10-15 lakh for a new unit, saving you 60-70%.

A properly sized and installed RECD has minimal impact on generator performance, typically less than 2-3% power loss. It does not affect fuel consumption significantly. Regular DPF regeneration (cleaning) ensures consistent performance.

Yes, the DPF element requires periodic regeneration (thermal cleaning) every 1,000-2,000 running hours depending on load and fuel quality. We include regeneration services in our RECD maintenance plans.
