Approved & Certified DG Sets for Commercial and Industrial Power
Approved & Certified DG Sets are diesel generator sets that carry the emission and noise approvals expected under Indian pollution-control rules. Businesses searching for an approved dg set, approved generators or a recd generator usually want one thing: a generator they can run without compliance trouble.
In practice, "approved" can mean two different things. A new genset may be certified by its manufacturer to CPCB IV+ norms. An older, in-use genset may instead be fitted with a Retrofit Emission Control Device (RECD) that has been tested and certified through a CPCB-recognised agency. Vardhman Diesel & Generators supports enquiries for both situations on a rental and hire basis.
Our fleet is drawn from established OEMs, including Cummins, Kirloskar, Mahindra Powerol, Jakson, Ashok Leyland and Caterpillar, and all CPCB IV+ equipment comes from these manufacturers. Brand, capacity and fuel availability vary by requirement, so please share your load and location when you enquire.
Contractors, factories, hospitals, data rooms and commercial buildings can request a quote and ask for the relevant certificates alongside the offer.
What Approved & Certified DG Sets Mean: Definitions and Documents
There is no single "approved" stamp that covers every generator. The table below separates the terms customers commonly mix up.
| Term |
What it refers to |
Documents worth asking for |
| CPCB IV+ genset |
A new diesel genset built to current CPCB emission norms. Manufacturers state that new sets must meet CPCB IV+ from 1 July 2023. |
OEM emission and noise compliance certificate, engine and alternator serial numbers |
| RECD generator |
An in-use diesel genset fitted with a Retrofit Emission Control Device to cut particulate emissions |
RECD type-approval certificate, vendor test report, installation record |
| Type-approved RECD |
A device tested on an equivalent kVA rating by an agency such as ARAI or I-CAT, with at least 70% particulate matter capture efficiency |
Test certificate matching your genset rating |
| Dual-fuel / gas genset |
A set running on gas or a gas-diesel mix, which CAQM treats differently from plain diesel sets in NCR |
Conversion or OEM documentation for the specific unit |
CPCB's RECD framework applies to diesel engines up to 800 kW gross mechanical power, which is roughly 1,000 kVA. Keep kW and kVA separate: they are not interchangeable units.
Approved & Certified DG Sets: Capacity Configurations and Specifications
Vardhman Diesel & Generators states a capacity range of 58 kVA to 2,000 kVA. The configurations referenced in our available fleet information are grouped below. Availability depends on stock and location.
| Configuration band |
Capacity references |
Typical selection considerations |
| Mid-range |
125 kVA, 160 kVA |
Offices, small plants, sites. Several state RECD circulars begin at 125 kVA and above, so check your state rule. |
| Higher capacity |
400 kVA, 500 kVA |
Factories, hospitals, large commercial buildings |
| Industrial |
750 kVA, 1,250 kVA, 1,500 kVA, 1,750 kVA, up to 2,000 kVA |
Heavy process loads, large campuses. Exact 2,000 kVA configuration is subject to confirmation. |
Exact engine make, alternator, enclosure and control panel details are confirmed in the quotation for the specific unit. We do not publish specifications that have not been verified for a given model.
Applications for Approved & Certified DG Sets by Industry
Approved generators matter most where regulators or tenders ask for compliance papers.
- Manufacturing and process plants: Continuous industrial loads need larger sets. In NCR, industrial and commercial use of sets up to 800 kW is allowed outside GRAP restriction periods, subject to CAQM conditions.
- Construction and infrastructure: Project sites often need short-term rental capacity and may be asked for emission certificates by the authority or client.
- Hospitals, hotels and commercial complexes: Backup power during grid failure. Emergency-service exceptions during GRAP are defined by CAQM, so confirm eligibility for your facility.
- Data rooms, warehouses and retail: Reliable standby with controlled noise through acoustic enclosures.
- Events and temporary installations: Short-term hire where documentation may be checked by local officials.
Selecting Approved & Certified DG Sets: Compliance and Capacity Checklist
Use these steps before you finalise approved & certified DG sets.
- Confirm whether you need a new CPCB IV+ set or an RECD generator. Rental of a new set avoids retrofit, while an existing site genset may need an RECD.
- Check your state and local rule. NCR is governed by CAQM directions. Maharashtra's MPCB issued an RECD circular in June 2023 for in-use sets up to 800 kW (1,000 kVA). Gujarat's pollution control board has also circulated RECD requirements. Rules are revised, so verify the current text.
- Size the load properly. Add starting currents for motors and future expansion.
- Understand GRAP. During GRAP Stage II to IV in NCR, DG use is heavily restricted, with limited exceptions linked to capacity, RECD fitment, dual-fuel operation and emergency purposes.
- Ask for documents in advance. A certificate should match the kVA rating and engine of the actual unit.
- Use certified vendors for RECD. CPCB maintains a list of RECD vendors on its website.

FAQs About Approved & Certified DG Sets
Approved & Certified DG Sets are generators that meet applicable pollution-control requirements. This usually means a new set certified to CPCB IV+ norms, or an in-use set fitted with a CPCB-recognised, type-approved RECD.
It generally means the unit has emission and noise compliance papers from the manufacturer or an RECD certificate. Ask for the document that matches the exact unit offered.
An RECD generator is a diesel genset fitted with a Retrofit Emission Control Device on its exhaust to reduce particulate matter. CPCB-linked procedures require testing by recognised agencies, and the commonly referenced standard is at least 70% particulate capture efficiency.
Vardhman Diesel & Generators states a range of 58 kVA to 2,000 kVA, with configurations such as 125, 160, 400, 500, 750, 1,250, 1,500 and 1,750 kVA. Availability depends on stock and the exact configuration.
Use during GRAP Stage II to IV is heavily restricted, with limited exceptions tied to emergency services, RECD fitment, capacity and dual-fuel operation. Approved & Certified DG Sets are not a blanket exemption, so check the current CAQM direction.
Not necessarily. New CPCB IV+ sets are built to current norms, while RECD rules mainly address in-use diesel sets. Requirements differ by state and capacity, so confirm the rule for your location.
Ask for the OEM compliance certificate for CPCB IV+ sets, or the RECD type-approval and vendor test report for retrofitted sets. The certificate should match the kVA rating and engine of the unit.
Capacity, rental duration, usage pattern, site conditions and the agreed contract all affect cost. Fuel, operator and transportation are normally quoted separately, subject to the contract.
Yes. Vardhman Diesel & Generators offers short-term and long-term arrangements, and you can request a quote with your duration and load details.
