RECD – Retrofit Emission Control

RECD – Retrofit Emission Control: Cleaner Exhaust for Your Existing Diesel Generator

Diesel generators keep homes, offices, factories and hospitals running during power cuts, but they also release smoke and harmful gases into the air. The RECD – Retrofit Emission Control from EOEnergy Pvt. Ltd. is designed to reduce these emissions without forcing you to replace your existing generator. It fits onto your current DG set and helps you run it more responsibly while meeting the pollution control requirements that apply in your region.

 

What Is a Retrofit Emission Control Device?

A Retrofit Emission Control Device (RECD) is an exhaust treatment system that is added to a diesel generator that is already installed and operating. The word “retrofit” simply means fitting new technology onto older equipment. Instead of buying a new, cleaner generator, you upgrade the one you own by adding a device that treats the exhaust before it leaves the stack. This makes RECD a practical and cost-conscious route to cleaner operation for businesses and institutions with working DG sets.

 

Why Emission Control on DG Sets Matters

Diesel exhaust contains particulate matter (PM), carbon monoxide (CO) and hydrocarbons (HC), along with other pollutants that affect air quality and public health. In busy urban and industrial regions such as Delhi-NCR, thousands of generators running during outages add to an already heavy pollution load. Regulators including the Central Pollution Control Board (CPCB) and the Commission for Air Quality Management (CAQM) have therefore introduced rules for operational DG sets, and approved emission control devices are one of the accepted ways to comply.

 

How the RECD Works

The RECD is installed in the exhaust line of the generator. As exhaust gases pass through the device, harmful components are captured or converted before being released into the atmosphere. The result is visibly cleaner exhaust and a lower pollution footprint from every hour your generator runs. The device is engineered so that it does not place undue strain on the engine, keeping back pressure within the limits recommended for the DG set. The unit is sized according to the kVA rating of your generator, so that it performs effectively for your specific installation.

 

Key Benefits

Lower emissions. The RECD helps reduce particulate matter, carbon monoxide and hydrocarbons from your generator’s exhaust, contributing to cleaner air around your premises.

Regulatory support. A properly certified device helps you meet CPCB and CAQM expectations for operational DG sets, reducing the risk of penalties, notices or shutdown orders.

No generator replacement. Because it is a retrofit solution, you keep your existing DG set and avoid the large expense of buying a new machine.

Engine-friendly design. Low back pressure design protects engine performance, fuel efficiency and service life.

Quieter operation. The device also acts as an additional silencer, helping reduce generator noise.

Sturdy build. Made with heavy-duty materials, the RECD is built to handle high exhaust temperatures and long running hours.

 

Where Can the RECD Be Used?

The RECD is suitable for a wide range of establishments that depend on diesel generators for backup or primary power. This includes industrial units and factories, residential societies and apartment complexes, commercial buildings and malls, hospitals and clinics, hotels and banquet halls, schools and colleges, offices and IT parks, and construction sites. Wherever a diesel generator is in regular use, retrofit emission control can help you operate in a cleaner and more compliant manner.

 

Compliance and Documentation

Compliance is not only about installing a device. It is also about being able to prove it. Authorities may ask for test certificates, approval details and installation records during inspections or when you apply for or renew your Consent to Operate. We recommend choosing a device that is type-approved as per CPCB procedure and testing, and keeping your documentation organised. EOEnergy supports customers with the paperwork that accompanies the installation, so that you have clear records to show whenever required.

 

Installation and After-Sales Support

A good result starts with the right assessment. Before installation, the condition of your DG set is checked and the site is reviewed to confirm that the device can be fitted correctly. Once the right unit is selected for your generator capacity, it is installed in the exhaust system by trained personnel. After installation, support continues with guidance on operation and servicing, so your equipment keeps performing as intended over time.

 

Simple Maintenance

The RECD is designed for practical day-to-day use. It needs only periodic inspection and servicing, which can be planned along with your regular generator maintenance. Following the recommended service schedule keeps the device working efficiently, protects your engine and helps you remain compliant through the year.

Frequently Asked Questions

1. What is a Retrofit Emission Control Device (RECD)?
An RECD is an exhaust treatment system fitted to an existing diesel generator. It helps reduce harmful emissions such as particulate matter (PM), carbon monoxide (CO) and hydrocarbons (HC) before the exhaust is released into the air, without requiring you to replace your generator.

2. Is RECD mandatory for diesel generators?
In many regions, including Delhi-NCR, operational diesel generators must follow CPCB and CAQM emission rules. Depending on your generator’s capacity and location, you may need a certified RECD or an alternative such as a dual fuel kit. Requirements and deadlines can change, so please confirm the latest rules with the pollution control authority or our team.

3. How do I know which RECD suits my generator?
The device is selected according to the kVA rating of your DG set. Share your generator’s capacity, brand and location, and our team will recommend the right unit after assessing your requirement.

4. Will the RECD affect my generator’s performance?
A properly selected and installed RECD is designed to keep back pressure within the engine’s permissible limits, so engine performance and life are not affected. A DG health check before installation helps ensure the device is fitted correctly.

5. What documents will I receive with the RECD?
You should receive the test or approval certificate and installation records, which can be shown to pollution control authorities during inspections or when applying for or renewing your Consent to Operate.
