Power outages don’t come with warnings and in India’s fast-growing urban and industrial ecosystem, diesel generator (DG) sets continue to play a mission-critical role. From hospitals and data centres to manufacturing units and residential complexes, DG sets ensure operational continuity when the grid fails. However, this reliability comes at a cost. Diesel generators are a significant source of particulate matter, toxic gases, and black carbon emissions, contributing heavily to deteriorating urban air quality.
Addressing this challenge requires more than temporary fixes—it demands advanced emission control innovation. This is where Retrofit Emission Control Devices (RECDs) have emerged as a decisive solution. Designed to dramatically reduce harmful exhaust emissions without compromising generator efficiency, modern RECD systems are now a regulatory and environmental necessity. Among the available solutions, Novorbis Itus has set a high industry benchmark by delivering CPCB-certified RECD solutions that combine durability, compliance assurance, and scalable performance.
As DG capacities increase and emission norms become more stringent, the market is rapidly shifting toward next-generation technologies. Innovations such as ARAI Type Approval and advanced filterless emission systems are redefining industry standards—clearly establishing what qualifies as the Best RECD in India for Diesel Generator Emission Control in today’s compliance-driven landscape.
Why Diesel Generator Emissions Can’t Be Ignored Anymore
Diesel generators are dependable, no doubt about it. But they come with a dirty secret—uncontrolled exhaust emissions. These emissions include microscopic particles and toxic gases that penetrate deep into human lungs, aggravating respiratory illnesses and worsening urban smog.
Left unchecked, DG emissions contribute to:
- Severe air quality deterioration in cities
- Increased risk of asthma, bronchitis, and cardiovascular disease
- Regulatory action and forced shutdowns
- Long-term environmental damage
That’s exactly why regulators stepped in—and why RECDs are now a necessity, not a luxury.
Retrofit Emission Control Devices (RECD): Precision Engineering for Cleaner Air
So, what exactly is an RECD?
A Retrofit Emission Control Device (RECD) is a high-performance emission abatement system designed to be retrofitted onto existing diesel engines. Instead of replacing your DG set (which would be costly and impractical), RECDs upgrade it, dramatically reducing emissions at the source.
Pollutants Targeted by RECD Systems
Modern RECDs are engineered to control and neutralise:
- Particulate Matter (PM2.5 & PM10)
- Carbon Monoxide (CO)
- Unburnt Hydrocarbons (HC)
- Nitrogen Oxides (NOx)
By combining high-efficiency filtration or catalytic processes with advanced thermal control, RECDs transform harmful exhaust into significantly cleaner output—without affecting power delivery, load response, or uptime. Sounds like a win-win? It absolutely is.
Regulatory Imperatives Driving RECD Adoption in India
India’s environmental compliance framework has tightened sharply over the last few years. In high-density and non-attainment cities, DG set emissions are under relentless scrutiny.
The Central Pollution Control Board (CPCB) has made RECD installation mandatory across a wide kVA range, introducing:
- Clear compliance deadlines
- Defined performance benchmarks
- Penalties for non-compliance
Operating a DG set without a CPCB-approved RECD can result in:
- Immediate operational shutdowns
- Heavy fines and legal action
- Notices from State Pollution Control Boards
- Serious reputational damage
In short, proactive RECD adoption ensures uninterrupted operations, regulatory peace, and future-ready compliance.
ARAI Type Approval and the Shift Toward High-Capacity Compliance
As DG capacities scale up, CPCB approval alone is no longer the finish line—especially for medium- and large-capacity generators.
This is where Automotive Research Association of India (ARAI) Type Approval has emerged as a critical benchmark. ARAI validation goes deeper, rigorously assessing:
- Emission performance under high loads
- Thermal safety and heat management
- Engine compatibility at elevated power ratings
In this high-capacity space, Novorbis has achieved ARAI Type Approval for its complete RECD range from 100 kW up to 771 kW, including the 771 kW category approved on 19th December. This milestone confirms that advanced RECD systems can deliver compliance without compromise, even where conventional solutions struggle.
CarbonFree™: Compact, Filterless, and Built for Large DG Sets
What truly sets this evolution apart is CarbonFree™—recognised as one of the world’s most compact, filterless RECD solutions for large DG sets in the 750 kVA and 910 kVA range.
By eliminating traditional filtration bottlenecks, CarbonFree™ avoids clogging altogether, maintains near-zero exhaust backpressure, and performs consistently even during continuous high-load operation.
Key Advantages of CarbonFree™ Technology
- ARAI-certified coverage from 100 kW to 771 kW
