Driving Cleaner Power for a Sustainable India
Diesel generator (DG) sets have long powered India’s commercial, residential, and industrial growth. However, their emissions contribute significantly to particulate matter and harmful gases that affect air quality. To combat this, the Central Pollution Control Board (CPCB) has mandated the installation of Retrofit Emission Control Devices (RECDs) on existing DG sets.
In its latest 2025 update, CPCB has released a verified list of certified RECD manufacturers authorized to provide emission control devices for DG sets up to 800 kW. At the forefront of this list stands Novorbis Itus., recognized for its ARAI-certified RECD solutions and commitment to technological innovation and environmental compliance.
As a leader in sustainable engineering, Novorbis is enabling organizations across India to meet emission standards efficiently while maintaining operational reliability.
What is a Retrofit Emission Control Device (RECD)?
A Retrofit Emission Control Device is a specialized after-treatment system designed to reduce pollutants emitted from diesel generator exhaust. Installed on existing engines, RECDs target key pollutants such as:
- Particulate Matter (PM)
- Carbon Monoxide (CO)
- Hydrocarbons (HC)
- Nitrogen Oxides (NOx)
By integrating advanced filtration and catalytic technologies, these devices help older DG sets comply with modern emission norms without requiring full equipment replacement.
Why RECDs Are Mandatory in 2025-26
The CPCB mandates that all in-use diesel gensets up to 800 kW capacity must be fitted with certified RECDs that conform to either Phase I or Phase II emission standards:
- Phase I: As specified in GSR 371(E), dated 17 May 2002
- Phase II: As specified in GSR 771(E), dated 11 December 2013
These norms ensure substantial reductions in particulate and gaseous emissions from DG operations. Failure to retrofit non-compliant gensets can result in penalties, operational shutdowns, and non-adherence to environmental clearances.

Understanding the Certification Agencies
- ARAI (The Automotive Research Association of India), Pune A premier research and certification body under the Ministry of Heavy Industries, responsible for testing and approving emission control technologies.
- ICAT (International Centre for Automotive Technology), Manesar A government-approved testing agency ensuring performance and emission compliance of vehicular and generator components.
Both agencies are authorized by CPCB to certify RECD manufacturers after comprehensive performance evaluations.
Selecting the Right RECD for Your Diesel Generator
When choosing an RECD, consider:
- Engine Capacity (in kW)
- Applicable Phase (I or II)
- Certification Agency (ARAI/ICAT)
- Manufacturer’s Service Capability
Selecting a CPCB-certified vendor such as Novorbis Itus. ensures compatibility, durability, and full regulatory adherence.
