buy RECD for generators onlineWhen you , the biggest concern should not be getting the lowest quotation—it should be confirming that the product is genuine, technically suitable and supported by proper documentation.

Online listings can make different RECD products look similar, but photographs, logos and attractive claims are not enough to establish authenticity or regulatory suitability. For an industrial application, buyers should verify the manufacturer, exact model, supporting documents and intended engine range before making payment. CPCB has published a specific procedure for emission-compliance testing of retrofit emission-control devices (RECDs) for diesel power-generating-set engines up to 800 kW gross mechanical power. The procedure was revised on July 24, 2023.

Why Genuine RECD Identification Matters

An RECD is not simply a generic exhaust accessory.

Its suitability can depend on factors such as:

DG-set engine
Engine model
Gross mechanical power
Applicable product range
Exhaust configuration
Installation requirements
Supporting technical documentation

A product that looks similar to another model may not necessarily have the same technical characteristics or applicability.

identity and documentation of the productThis is why buyers should evaluate the , not just its physical appearance.

What Makes an RECD Purchase Trustworthy?

A reliable purchase should provide a clear connection between:

Supplier → Manufacturer → Product Model → Technical Documentation → Application

If one of these links is unclear, ask additional questions before proceeding.

For example, if a seller offers an RECD but cannot tell you who manufactures it or which model is being supplied, the quotation deserves further investigation.

1. Verify the Manufacturer's Identity

Start with the company behind the product.

Ask the seller:

“Who is the original manufacturer of this RECD?”

Then check whether the manufacturer has an identifiable business presence and relevant product information.

Look for:

Official company website
Company address
Business contact information
Product catalogue
Technical documentation
Manufacturer name on documents

A reseller should also be able to explain its relationship with the manufacturer where relevant.

2. Ask for the Exact Product Model

A vague product description is a warning sign.

For example:

“CPCB RECD for diesel generator”

doesn't identify a particular product.

Ask for:

Model number
Product name
Manufacturer
Applicable engine-power range
Technical datasheet

The model number should remain consistent across the quotation, datasheet and relevant supporting documentation.

3. Compare the Product With Official CPCB Information

CPCB publishes information on RECD manufacturers certified for applicable diesel genset engines up to 800 kW.

Its published list dated May 9, 2025 identifies manufacturers, applicable in-use diesel genset engine-power ranges, Phase I/Phase II applicability and certification agencies.

This is useful when checking a supplier's claims.

every product or model advertised by that company or reseller is suitable for every DG setHowever, buyers should not interpret the presence of a company on an official list as automatic confirmation that .

The exact product and application still need to be verified.

4. Don't Treat a CPCB Logo as Proof

One common online mistake is assuming that a logo or statement such as:

“CPCB Approved”

is enough evidence.

It isn't.

Ask the supplier for relevant supporting documentation and determine:

Which manufacturer is identified?
Which RECD model is covered?
What engine range applies?
Which certification agency is identified?
Does the documentation correspond to the product being offered?

This is far more useful than relying on a badge displayed on a website or marketplace listing.

5. Check the Technical Datasheet

A genuine industrial product should normally have identifiable technical information.

Review the supplied datasheet for:

Manufacturer
Model number
Dimensions
Weight
Application range
Installation information
Maintenance requirements
Technical specifications

If the seller provides only a photograph and a price without meaningful technical information, ask for more documentation.

6. Check Whether the Product Matches Your DG

Never assume that a product is suitable merely because the seller knows your DG's kVA rating.

Provide:

Engine manufacturer
Engine model
Engine power
DG capacity
Exhaust information

CPCB's published RECD list itself shows different applicability ranges across manufacturers. For example, the listed ranges vary according to engine power and Phase.

That is why product selection should be based on the actual engine/application rather than a generic “works with DG sets” statement.

7. Be Careful With Extremely Cheap Products

Price alone does not prove that a product is fake.

However, an unusually low quotation deserves closer examination.

Ask:

“What exactly is included in this price?”

The lower price may exclude:

Installation
Fabrication
Transportation
Commissioning
Warranty
Technical support

It could also represent a different product specification.

The correct approach is to investigate the difference rather than immediately assuming the product is counterfeit.

9. Check the Seller, Not Just the Product

An authentic product can also be sold through different channels.

The seller could be:

Manufacturer
Authorized distributor
Dealer
Industrial supplier
Reseller

Ask:

“Are you the manufacturer or a distributor?”

If they are a distributor, ask who will provide:

Warranty
Technical support
Spare parts
Installation

This becomes particularly important when purchasing online from a company you have never dealt with before.

10. Ask for a Formal Quotation

Avoid making a large industrial purchase solely through a chat message.

Request a formal quotation containing:

Supplier name
Product manufacturer
Product model
Quantity
Technical scope
Price
Taxes
Transportation
Installation
Delivery schedule
Warranty

A proper quotation provides a clearer record of what you are actually buying.

11. Verify the Company Before Making Payment

Before transferring money, check the supplier's basic business information.

Where applicable, verify:

Legal/business name
Official website
Business email
GST information
Registered contact details
Quotation
Bank-account details

Be cautious if the seller asks you to transfer a substantial amount to an unrelated personal bank account or refuses to issue proper commercial documentation.

12. Beware of Fake Certification Claims

Certification claims deserve special attention.

CPCB itself has issued a public notice warning about individuals falsely claiming to be CPCB officials or consultants and attempting to obtain work or influence organizations.

The lesson for RECD buyers is simple:

Don't rely on someone merely saying that they represent CPCB or can “arrange CPCB approval.”

Verify regulatory information directly through official sources.

13. Check the Certification Agency Information

CPCB's published RECD manufacturer list identifies certification agencies for the listed manufacturers and applicability ranges.

When a supplier provides certification information, compare the details with the relevant official information.

Ask:

Which agency conducted the certification?
What manufacturer is named?
What model is covered?
What engine range is covered?
Does the documentation correspond to the quoted product?

These questions can expose inconsistencies early.

14. Don't Trust Product Photographs Alone

Two different RECD products may look almost identical in online photographs.

Visual similarity does not establish:

Same manufacturer
Same internal design
Same technical performance
Same certification
Same application range

Therefore, use photographs for identification—not as proof of authenticity.

15. Ask for Product-Specific Documentation

Before placing an order, request relevant documents such as:

Technical datasheet
Product specification
Installation instructions
Applicable certification information
Relevant Type Approval documentation
Warranty terms

The exact documentation required may depend on the product and application.

same model being quotedMost importantly, check whether the documents identify the .

16. Check the Warranty Carefully

A questionable supplier may simply say:

“One-year warranty.”

Ask what that actually means.

Confirm:

Warranty duration
Start date
Covered components
Labour coverage
Site-visit terms
Transportation during warranty claims
Exclusions

Also identify who is responsible for the warranty—the manufacturer, distributor or seller.

17. Investigate After-Sales Service

A genuine product from an unreliable supplier can still become a difficult purchase if technical support is unavailable.

Ask:

Who handles installation?
Are service engineers available?
Where are they located?
Are spare parts available?
How are warranty complaints handled?
Can the supplier visit your site?

For a working DG installation, support after delivery can be just as important as the initial purchase.

18. Verify the Exhaust Installation Requirements

An RECD must be considered in relation to the generator's exhaust arrangement.

Before ordering, provide information about:

Exhaust-pipe diameter
Existing silencer
Flanges
Pipe routing
Available installation space
Mounting arrangement

The supplier should explain whether fabrication or modification is required.

CPCB's RECD testing procedure includes technical considerations associated with the exhaust system, so installation should not be treated as an afterthought.

19. Don't Buy Based on “Universal” Claims

A product described as:

“Universal RECD for every DG”

should be examined carefully.

Different engines can have different:

Power ranges
Exhaust configurations
Operating conditions
Technical requirements

Ask the supplier to explain exactly how the proposed model applies to your generator.

A technically responsible supplier should request your DG and engine information before finalizing the product.

20. Check the Complete Cost

A genuine product can still become an expensive purchase if additional costs are hidden.

Ask whether the quotation includes:

Equipment
Installation
Fabrication
Transportation
Commissioning
Taxes
Warranty
Service

This is particularly important when comparing a manufacturer quotation with a marketplace listing.

21. Understand the RECD Price for DG Set

RECD price for DG setThe is not necessarily a single standard market price.

The final quotation can depend on:

Engine power
Engine model
RECD model
Quantity
Exhaust modifications
Installation location
Fabrication
Transportation
Warranty
Service scope

Therefore, don't judge authenticity based solely on whether the quoted price is high or low.

A more useful test is whether the supplier can explain the price and provide appropriate product documentation.

22. Request a DG-Specific Quotation

For a better quotation, send the supplier:

Engine manufacturer: ______

Engine model: ______

Gross mechanical power: ______

DG rating: ______ kVA

Exhaust diameter: ______

Quantity: ______

Installation location: ______

Attach photographs of the DG nameplate and exhaust arrangement.

This reduces the possibility of receiving a generic product recommendation.

23. Check Delivery Information

Before paying, confirm:

Product availability
Manufacturing lead time
Dispatch date
Delivery date
Installation schedule

exact modelIf the supplier claims “ready stock,” ask whether the quoted is available.

Don't assume that a generic listing means immediate availability.

24. What to Do if Two Suppliers Offer Similar Products

Suppose Supplier A and Supplier B offer apparently identical RECDs.

Don't choose immediately based on price.

Compare:

Supplier A

Manufacturer identified
Model identified
Documentation available
Installation included
Warranty documented

Supplier B

Lower price
Generic product description
Limited documents
Warranty unclear
Installation not defined

Supplier A may provide greater purchasing confidence even if the initial quotation is higher.

25. A Simple Authenticity Verification Process

Use this five-step check:

Step 1: Identify

Find the actual manufacturer and model.

Step 2: Document

Request the technical datasheet and relevant supporting documents.

Step 3: Match

Confirm that the model on the quotation matches the documents.

Step 4: Verify

Cross-check applicable information with official CPCB sources.

Step 5: Confirm

Only then finalize price, delivery, installation and warranty.

This process is much safer than purchasing solely from an online product image.

26. Red Flags Before You Order

Stop and investigate further if a supplier:

Cannot identify the manufacturer
Has no model number
Refuses to provide a datasheet
Makes unexplained certification claims
Promises universal compatibility
Offers an unusually low price without explaining the scope
Refuses to provide a formal quotation
Gives unclear warranty terms
Cannot explain installation requirements
Claims to represent CPCB without verifiable authority

One red flag does not automatically prove fraud, but multiple unresolved issues should make you reconsider the purchase.

27. Don't Confuse a Reseller With a Fake Product

A product being sold by a reseller does not automatically make it fake.

A legitimate reseller may provide genuine equipment manufactured by another company.

The important questions are:

Is the manufacturer identifiable?
Is the product model identifiable?
Can the reseller explain its supply relationship?
Are relevant documents available?
Is warranty responsibility clear?

This distinction is important when evaluating online suppliers fairly.

28. Verify Before Installation, Not After a Problem

Waiting until the product arrives to check documentation creates unnecessary risk.

The best time to verify:

Before payment → Before dispatch → Before installation

If the supplier cannot provide adequate information before the order, don't assume everything will become clear after delivery.

29. Keep Your Purchase Records

Maintain copies of:

Quotation
Purchase order
Invoice
Product datasheet
Certification documents
Warranty
Installation report
Supplier communication

These records can be useful for future maintenance, warranty claims and internal compliance documentation.

30. Use Official Sources for Regulatory Verification

CPCB's website provides a dedicated Generator Sets section containing Type Approval/COP information.

Its RECD procedure and manufacturer information should be checked when evaluating relevant products and suppliers.

However, official documents should be interpreted in the context of the specific generator, product and applicable requirements. A general statement about RECDs should not be treated as an automatic compliance declaration for an individual DG installation.
