Before selecting a RECD device as per CPCB norms, DG set owners should evaluate the generator's specifications, exhaust configuration, operating conditions, technical requirements, and the current regulations applicable to their installation. Diesel generator sets play an important role in providing backup and standby power for businesses, institutions, industries, healthcare facilities, data centers, hotels, and infrastructure projects. As organizations pay greater attention to emission management, retrofit emission-control solutions are increasingly being considered for suitable existing DG installations. Buying an RECD online can make the search process easier, but finding the right device requires careful evaluation. A product that looks suitable in an online listing may not necessarily be appropriate for your particular engine or exhaust system. This guide explains how to choose, check, and purchase an RECD while avoiding common buying mistakes.
What Is an RECD for a DG Set?
RECD stands for Retrofit Emission Control Device. It refers to an emission-control system designed for installation with a suitable existing ...
... diesel generator. Depending on the technology, an RECD may use filtration, oxidation, sensors, controllers, monitoring functions, or other components to support emission management. The exact design and performance characteristics can differ between systems. Therefore, the device should be selected according to the generator and application rather than treating every RECD as interchangeable.
Why RECD Selection Requires Technical Evaluation
An RECD is connected to the generator's exhaust system, so its suitability can depend on several technical factors. These can include:
Generator capacity
Engine manufacturer
Engine model
Engine speed
Exhaust flow characteristics
Exhaust temperature
Exhaust pipe dimensions
Operating load
Operating hours
Installation environment
Maintenance requirements
This is why the selection process should begin with the DG set's technical information.
Step 1: Identify Your DG Set
The first step is to gather the information required for a technical assessment. Check the generator nameplate and available documentation for:
DG set manufacturer
Engine manufacturer
Engine model
Rated kVA
Rated RPM
Manufacturing or installation details where relevant
Exhaust outlet information
If possible, also provide photographs of the generator nameplate and exhaust arrangement when requesting a quotation. This can make it easier for the supplier to understand the application.
Step 2: Examine the Exhaust System
The existing exhaust arrangement is an important part of RECD selection. Before ordering, determine:
Exhaust pipe diameter
Exhaust outlet position
Pipe routing
Available installation space
Mounting points
Existing supports
Access for maintenance
Depending on the proposed RECD, the exhaust system may need modifications. Understanding these requirements before purchasing can help prevent installation delays.
Step 3: Understand Your Operating Conditions
The generator's operating pattern should also be considered. Ask yourself:
How frequently is the DG set operated?
What is its typical operating load?
How long does it normally run?
Is it used only during power outages?
Does it operate for extended periods?
Are there multiple DG sets operating together?
Provide this information to the supplier. Operating conditions can help the technical team determine whether a particular RECD configuration is appropriate for the application.
Step 4: Compare Available RECD Technologies
RECD systems can differ in their design and emission-control technology. Depending on the product, the system may include:
Filtration technology
Oxidation components
Sensors
Controllers
Temperature monitoring
Pressure monitoring
Status indicators
Other control or monitoring functions
Instead of choosing a system simply because it has more components, evaluate whether its features are relevant to your DG set. Ask the supplier to explain the technology in relation to your specific application.
Step 5: Review the Technical Datasheet
Never finalize a technical equipment purchase based solely on an online product title. Request a detailed datasheet and review:
Supported DG capacity
Compatible engine applications
Device dimensions
Weight
Exhaust connection
Operating conditions
Monitoring features
Control requirements
Maintenance requirements
Installation instructions
If any specification is unclear, request clarification before ordering.
Step 6: Check the Emission-Control Information
Understand what the proposed RECD is designed to control. Ask the supplier:
Which emissions is the system intended to address?
What technology is used?
What performance information is available?
Under what operating conditions is the stated performance applicable?
Is supporting test or technical documentation available?
Avoid accepting broad performance statements without understanding the conditions behind them.
Step 7: Understand CPCB-Related Requirements
CPCB-related requirements should be treated carefully during RECD selection. The applicable requirements for diesel generator sets can depend on factors such as:
Generator capacity
Engine specifications
Installation circumstances
Applicable environmental notifications
Generator category
Other site-specific or regulatory conditions
Therefore, a general statement such as "CPCB approved RECD" should not automatically be interpreted as confirmation that the product satisfies every requirement for every DG set. If the purpose of your purchase is compliance-related, request relevant supporting documentation from the supplier and verify the current requirements applicable to your particular generator through official regulatory sources.
Step 8: Compare Suppliers
Once you understand your requirement, compare several suppliers where practical.
Technical Capability
Can the supplier evaluate your exact DG set?
Product Documentation
Are detailed technical specifications available?
Installation Support
Can the supplier assist with installation and commissioning?
Service
Is technical support available after installation?
Spare Parts
Are replacement components available?
Warranty
Are warranty conditions clearly explained? A supplier's ability to support the equipment after delivery can be as important as the initial product price.
Step 9: Request an Application-Specific Quotation
When you request a quotation, provide complete information about your generator.
For example:
DG Set: 500 kVA
Engine: Manufacturer and model
RPM: Rated speed
Exhaust: Pipe diameter and arrangement
Operating Load: Typical load
Usage: Backup or regular operation
Installation: Available site information
This gives the supplier enough information to prepare a more relevant quotation.
Step 10: Compare the Complete Price
The equipment price should not be the only number you compare. A quotation may include or exclude:
RECD equipment
Sensors
Controllers
Accessories
Exhaust modifications
Installation
Commissioning
Transportation
Taxes
Warranty
Maintenance
Service
When you buy RECD for generator online, ask suppliers to clearly identify what is included in the quoted amount. This allows you to compare quotations more fairly.
Why the Lowest Price May Not Be the Best Choice
Price is important, but an emission-control system is a long-term technical investment. A low-cost quotation may not include installation, technical support, documentation, or certain accessories.
What am I actually receiving for the quoted price?
Then compare the complete package. Factors such as warranty, service availability, maintenance support, and technical documentation can affect the overall value of the purchase.
Step 11: Check Installation Requirements
Before ordering, understand how the RECD will be integrated with the generator.
Mounting arrangement
Exhaust connection
Pipe modifications
Available space
Electrical requirements
Sensor installation
Controller installation
Maintenance access
For complicated installations, a site inspection can help identify potential issues before equipment delivery.
Step 12: Review Maintenance Requirements
Ask the supplier about routine maintenance before making a purchase. Important questions include:
Does the device require regular cleaning?
Are there replaceable components?
How frequently should inspections be performed?
Are sensors or controllers subject to maintenance?
What spare parts are required?
Is maintenance service available?
Following the manufacturer's maintenance recommendations can help support reliable operation.
Step 13: Check Warranty Coverage
Warranty terms can vary between products and suppliers.
Warranty duration
Covered components
Installation conditions
