Retrofit Emission Control Device (RECD) – Clean Air Technology for Diesel Generators

Vayu Pure RECD by Inventive Gas Equipment is a CPCB-approved emission control device for diesel generators, engineered to cut down particulate matter, hydrocarbons, and carbon monoxide for cleaner air and regulatory compliance.

Retrofit Emission Control Device (RECD) – Clean Air Technology for Diesel Generators

With increasing concerns over air pollution from diesel generators, the need for effective emission control technologies has never been greater. To tackle this issue, the Government of India and the Central Pollution Control Board (CPCB) have made it mandatory for diesel generator operators to install Retrofit Emission Control Devices (RECDs) — a proven solution for reducing harmful exhaust emissions.

At Inventive Gas Equipment Pvt. Ltd., we proudly offer Vayu Pure RECD — an advanced, CPCB-approved emission control device engineered to significantly cut down particulate matter (PM), hydrocarbons (HC), and carbon monoxide (CO) from diesel genset exhausts.

What Is a Retrofit Emission Control Device (RECD)?

A Retrofit Emission Control Device (RECD) is a specialized pollution control system installed in the exhaust of diesel generators. It filters and neutralizes harmful pollutants before they are released into the atmosphere.

The RECD works on a filtration and catalytic oxidation principle, ensuring that emissions from diesel gensets are reduced by up to 90%, depending on the engine’s load and condition.

Key Pollutants Controlled by RECD:

• Particulate Matter (PM 2.5 and PM 10)
• Carbon Monoxide (CO)
• Hydrocarbons (HC)
• Nitrogen Oxides (NOx) (in advanced systems)

RECD – A Step Toward Sustainable Power

As India advances toward cleaner industrial growth, adopting Retrofit Emission Control Devices is no longer an option — it’s a responsibility. The Vayu Pure RECD by Inventive Gas Equipment empowers organizations to meet compliance, reduce carbon footprint, and operate responsibly without sacrificing power reliability.

Together, we can power progress — while protecting the planet.

Suggested Meta Description:

Vayu Pure RECD by Inventive Gas Equipment – CPCB-approved Retrofit Emission Control Device for diesel generators. Achieve up to 90% emission reduction and meet NGT norms.

The Need for RECD in India

According to the Central Pollution Control Board, diesel gensets contribute significantly to particulate pollution in urban areas. To counter this:

• The National Green Tribunal (NGT) has mandated RECD installation on all DG sets.
• State Pollution Control Boards (SPCBs) monitor compliance.

Industries and institutions are encouraged to adopt emission control devices to meet environmental standards.

With over 3 million diesel gensets operating nationwide, retrofitting them with certified RECDs can drastically improve urban air quality and help India progress toward its Net Zero 2070 target.

Benefits of Installing a Retrofit Emission Control Device

1. Up to 90% Emission Reduction

Effectively eliminates harmful pollutants and soot from diesel generator exhausts, ensuring compliance with CPCB/NGT norms.

2. Legal Compliance

As per CPCB guidelines, all diesel gensets above 125 kVA must be equipped with a certified RECD system to operate legally in India.

3. Improved Air Quality

Installing an RECD significantly improves ambient air quality, reducing the health impact on nearby communities and workers.

4. Enhanced Engine Efficiency

By maintaining optimal exhaust backpressure, the Vayu Pure RECD ensures engine performance remains unaffected, while contributing to cleaner operations.

5. Low Maintenance & Long Life

With automatic regeneration and robust material construction, our RECDs are built for long-term reliability under diverse operating conditions.

How Does an RECD Work?

The Vayu Pure Retrofit Emission Control Device is designed with multiple layers of filtration and catalytic conversion to achieve optimal purification.

Step-by-step process:

• Diesel Exhaust Entry — The exhaust gases from the genset enter the RECD system.
• Filtration Stage — A ceramic or metallic filter traps soot and particulate matter.
• Catalytic Oxidation — A catalyst-coated substrate converts CO and HC into harmless CO₂ and H₂O.
• Regeneration — The filter cleans itself through passive or active regeneration, maintaining consistent performance.

This process ensures that cleaner air is released into the environment while maintaining genset efficiency.
