Keep Your Existing Genset Running & CPCB IV+ Compliant
You do not need to discard a reliable diesel generator to satisfy statutory environmental directives. Our type-approved Retrofit Emission Control Devices (RECD) capture particulate emissions at the exhaust source — delivering audit-ready compliance in 1 to 2 days at a fraction of replacement cost.
Retrofit or Replace? The Real Decision Framework
Replacing an operational generator involves crane logistics, civil restructuring, and high capital outlay. Here is how type-approved RECD compares.
| Decision Parameter | AADEO RECD Retrofit | Full CPCB IV+ Genset Replacement |
|---|---|---|
| Capital Expenditure (CapEx) | Substantially lower (Fraction of new equipment) | High CapEx (Rs. 8–25+ Lakhs depending on kVA) |
| Installation Downtime | 1 to 2 days on-site | 3 to 6 weeks (Procurement, rigging & civil rebuild) |
| Civil & Plantroom Alterations | Zero (Exhaust pipe integration only) | Extensive foundation, crane rigging & cable rerouting |
| Statutory Outcome | Fully CPCB IV+ / CAQM compliant (In-use sets) | Fully CPCB IV+ compliant |
| Ideal Application | Gensets with healthy compression & remaining useful life | Severely aged units (>15 years) or undersized capacity |
Calibrated Low Backpressure (<50 mbar)
The primary risk of poorly designed aftermarket emission filters is excessive exhaust backpressure. When backpressure exceeds OEM thresholds, exhaust gas temperature spikes, fuel consumption rises, and turbocharger seals degrade.
Zero Engine Derating
Aerodynamically optimized cell matrices ensure engine kilowatt output and transient load response remain at 100% rated capacity.
Automated Electronic Differential Pressure Telemetry
Continuous sensor monitoring tracks pressure differential across the filter element and alerts operators if cleaning is due.
Thermal Expansion Bellows & Bypass Safety
Integrated high-temperature flex bellows prevent vibration fracture, while safety fail-safes protect the generator under all operating loads.
RECD Operational BenchmarksStandard CPCB-PCLS/12/2021-22
Engine Compatibility
Compatible with leading industrial diesel engines including Cummins, Kirloskar Oil Engines, Perkins, Mahindra, Caterpillar, and Volvo Penta across all standard ratings up to 910 kVA.
What We Provide for Your Statutory Compliance File
Pollution control board audits require verifiable documentation, not verbal promises. Every AADEO RECD retrofit includes this 4-part legal package:
Type Approval Certificate
Official type approval test certificate issued by accredited testing agencies under CPCB-PCLS/12/2021-22.
Pre & Post Emission Test Report
On-site flue gas emission measurements validating baseline vs post-retrofit particulate reduction on load.
Tamper-Proof Serial Plate
Physical laser-etched metal badge riveted to the device displaying device serial number, model, and approval reference.
SPCB Consent Filing Letter
Formal installation sign-off document formatted for submission to Haryana SPCB, DPCC, or respective state authorities.
