Choosing an RECD manufacturer in Gurugram requires careful verification because the market includes manufacturers, suppliers, installation companies and resellers offering products under similar descriptions. A low price or a “CPCB approved” label should not be enough to decide which product is genuine or appropriate for a particular DG set. For industrial and commercial buyers, the safer approach is to verify the manufacturer, exact RECD model, engine application, technical documents, installation scope and warranty before placing an order.

CPCB has published a procedure for emission-compliance testing of Retrofit Emission Control Devices for diesel power-generating-set engines up to 800 kW gross mechanical power. The procedure was revised on July 24, 2023.

What Makes an RECD Product Genuine?

A genuine RECD should be identifiable and traceable.

Before buying, you should be able to establish:

• Manufacturer name

• Manufacturing location

• Exact RECD model/type

• Applicable engine or power range

• Relevant Type Approval/test information

• Product identification or serial number

• Installation requirements

• Warranty responsibility

CPCB's RECD procedure contains specific provisions relating to manufacturer information and conformance labelling. The procedure requires information including the manufacturer or Type Approval certificate holder, manufacturing plant address, RECD model, class, part number, unique identification number, manufacturing date and Type Approval certificate number on the conformity label.

That makes product traceability one of the first things a buyer should check.

1. Verify Who Actually Manufactures the Product

A company selling an RECD is not automatically the manufacturer.

Before approving the purchase, ask:

“Who manufactures this exact RECD?”

Then establish whether the company is acting as:

• Manufacturer

• Supplier

• Distributor

• Installer

• Service provider

This distinction matters because the certification and product documentation should relate to the actual RECD manufacturer and model.

CPCB's published supplier-profile documentation also distinguishes between manufacturers, retrofitters and importers.

2. Ask for the Exact RECD Model

Avoid quotations that simply say:

“RECD system – 1 No.”

A proper quotation should identify:

• Manufacturer

• Model/type

• Product series

• Applicable engine range

• Part/identification number where applicable

• Quantity

The model on the quotation should match the model on the datasheet and supporting documents.

If the supplier provides a certificate for one model but quotes another model, ask for clarification before making payment.

3. Match the Product to Your DG Engine

A product can be genuine but still be unsuitable for your generator.

Provide the supplier with:

• Engine manufacturer

• Engine model

• Engine serial number

• Gross mechanical power

• DG rating

• Rated speed

CPCB's RECD framework is based on specific engine applications and gross mechanical power, so selecting an RECD only from the DG's kVA rating is not sufficient.

For example, two generators with similar kVA ratings can have different engine configurations and therefore require separate application verification.

4. Verify the Supporting Documentation

A genuine product should have documentation that can be connected to the exact model being offered.

Ask for:

Technical Documents

• Product datasheet

• Exact model/type

• Application range

• Installation requirements

Certification/Test Documents

• Relevant Type Approval information

• Test documentation

• Certification agency

• Applicable Phase

Commercial Documents

• Warranty

• Installation scope

• Maintenance instructions

CPCB's published manufacturer information lists specific RECD manufacturers, engine-power ranges and certification agencies, providing a useful reference for verification.

For a 2026 purchase, check the latest official version rather than assuming an older list is still current.

5. Check the Physical Product Label

When the equipment reaches the site, compare the actual RECD with the documents.

Check for:

• Manufacturer

• Model

• Serial/unique identification

• Manufacturing information

• Type Approval identification where applicable

• Conformance label

CPCB's procedure contains specific requirements for RECD conformance labelling.

An inconsistent label is a reason to stop and verify the product before installation.

6. A Very Low Price Should Trigger Questions

A low price does not automatically mean a product is fake or non-compliant.

The difference could simply result from:

• Equipment-only pricing

• Different product configuration

• Installation excluded

• Fabrication excluded

• Transportation excluded

• Warranty differences

• Quantity discounts

The right question is not:

“Why is this product so cheap?”

It is:

“What exactly is included in this quotation?”

Compare complete project costs before making a decision.

Genuine vs Unclear Product

This is a procurement screening guide, not a legal definition of compliance.

7. Don't Confuse a Supplier With a Manufacturer

The Gurugram market may include:

Manufacturers

Companies that make the RECD.

Suppliers

Companies that sell products made by another company.

Installation providers

Companies that install or service RECDs.

Turnkey contractors

Companies coordinating equipment and site execution.

There is nothing inherently wrong with buying through a supplier or installer.

The important question is whether the buyer knows who manufactured the actual device and who is responsible for its warranty and technical documentation.

8. Look at the Gurugram Market Carefully

Several companies with Gurugram operations have publicly available RECD information.

Aceget Private Limited

Aceget identifies Noida as its headquarters and publishes information about its Aceget Shield RECD.

Automoto Genset Solutions

Automoto identifies its Gurugram corporate location and publishes information on its Vaayu Mitra RECD.

JBDS Power

JBDS identifies a manufacturing location in Gurugram for its retrofit emission-control products.

These companies should still be evaluated model by model, rather than assuming every product from a company has identical certification or application.

9. Review the Manufacturer's Delhi-NCR Connection Carefully

A company may have:

• Corporate office in Gurugram

• Manufacturing facility elsewhere

• Service team in another city

• Third-party installers in some regions

This is not automatically a problem.

Ask:

Where is this specific RECD manufactured?

Who will install it?

Who handles the warranty?

Where are spare parts stocked?

Knowing the actual supply chain can prevent confusion later.

10. Don't Accept Generic “CPCB Approved” Claims

One of the biggest red flags is an unsupported statement such as:

“100% CPCB approved for all DG sets.”

That statement raises several questions.

Which product?

Which engine?

Which application range?

Which certificate?

Which testing agency?

Which Phase?

Which current requirement?

CPCB's RECD procedure establishes a testing and type-approval framework; a generic marketing statement is not a substitute for product-specific verification.

11. Product Certification Does Not Automatically Equal Site Compliance

A genuine, appropriately documented RECD is still only one component of a broader compliance assessment.

The actual position can depend on:

• DG specifications

• RECD model

• Installation

• Location

• Current regulatory requirements

• State/UT requirements

• Site-specific directions

Therefore:

Product approval ≠ automatic blanket site compliance

This distinction should be made clear in procurement and marketing material.

12. Check Installation Quality

A genuine product can still cause problems if incorrectly installed.

Before commissioning, review:

• Exhaust-pipe dimensions

• Flanges

• Mounting

• Supports

• Fabrication

• Maintenance clearance

• Relevant sensor/controller connections

CPCB's published RECD procedure includes exhaust back pressure among its technical considerations.

Therefore, installation should be planned around the specific DG and RECD rather than using an identical method for every generator.

13. Ask About Maintenance and Spare Parts

A genuine product should also have a clear service path.

Ask:

• What maintenance is required?

• Which parts are replaceable?

• Where are spare parts available?

• What is the expected delivery time?

• Who performs repairs?

• What is covered under warranty?

A manufacturer that cannot explain how the product will be supported after installation deserves closer scrutiny.

14. Check Performance Claims Carefully

An RECD supplier may advertise a large percentage reduction.

Before using the figure for procurement, ask:

• Which pollutant?

• Which product?

• Which engine?

• What baseline?

• Which testing conditions?

• Which agency?

• Is the result applicable to my generator?

Don't treat a test result for one configuration as a guaranteed result for every DG.

For example, published product information from Gurugram-based companies may state emission-reduction or particulate-capture figures, but those claims should be evaluated against the exact model and supporting test documentation.

15. Check Whether the Certification Belongs to the Same Model

This is a particularly useful verification step.

Suppose:

Quotation: Model X

Datasheet: Model X

Certificate: Model Y

That does not automatically mean something is wrong, but the supplier must explain the relationship.

Do not assume that a certificate for one RECD model automatically covers another product.

Product identity should be traceable.

16. Where the RECD supplier for DG sets Fits Into Verification

A trustworthy RECD supplier for DG sets should be able to provide a clear chain:

Manufacturer

→ Exact model

→ Engine application

→ Supporting documents

→ Installation

→ Commissioning

→ Warranty

→ Service

If any major link is unclear, ask questions before approving the purchase.

17. Check Warranty Terms Before Installation

Ask:

• Warranty period

• Warranty start date

• Covered components

• Installation coverage

• Labour

• Site visits

• Exclusions

• Replacement procedure

Also ask whether the manufacturer requires an authorized or specified installation method for warranty validity.

This can be particularly important when the equipment supplier and installation contractor are different companies.

18. Inspect the Product Before Commissioning

After delivery and before final commissioning:

• Verify manufacturer

• Verify model

• Check serial/identification number

• Inspect the product label

• Match against purchase order

• Match against supporting documents

If anything differs, document the discrepancy before commissioning.

19. Maintain a Product Verification File

For each DG, keep:

DG

• Engine model

• Gross mechanical power

• DG rating

RECD

• Manufacturer

• Model

• Serial number

• Datasheet

Documentation

• Type Approval/test information

• Certification agency

• Installation instructions

Project

• Site survey

• Installation report

• Commissioning report

• Warranty

This creates a traceable record for future service and audits.

20. Don't Judge “Non-Compliant” From Price Alone

It is important not to label a product “non-compliant” merely because:

• It is cheaper

• It is from a small company

• The factory is outside Gurugram

• The product looks different

• It has a newer design

A compliance conclusion should be based on the applicable official requirements and product documentation.

The safer wording for procurement teams is:

“Documentation could not be verified”

rather than making an unsupported allegation that a particular product is fraudulent or non-compliant.

21. Current Official Verification Matters in 2026

CPCB's official resources should be checked when evaluating RECD claims.

Its published RECD procedure establishes the testing/type-approval framework, while its manufacturer list provides manufacturer-specific application information.

CPCB also maintains a Generator Sets section containing Type Approval/COP information.

For a purchase in 2026, verify whether any newer official notification, manufacturer list or requirement has been issued.

Conclusion

For buyers searching for a genuine RECD manufacturer in Gurugram, the safest strategy is to verify the complete product trail rather than relying on price, location or marketing claims. Start by confirming who actually manufactures the RECD. Then verify the exact model, engine application, gross mechanical power and relevant technical documentation. Once the equipment reaches the site, check the product identification and ensure that the installation matches the agreed scope. Gurugram has several companies active in the RECD market, including Aceget Private Limited, Automoto Genset Solutions and JBDS Power. Their public information shows different products, locations and technical claims, which is why buyers should compare the exact model and documentation rather than selecting a company based solely on name recognition.  A genuine RECD purchase is one where the manufacturer, model, application and supporting documents can all be connected clearly to the equipment installed on the DG.
