RECD for DG Set Device & FAQ? Retrofit Emission Control Device

One of the most reliable options available today is the RECD – Retrofit Emission Control Device.In today’s industrial environment, controlling emissions from diesel generator (DG) sets has become a legal and environmental necessity. With tightening norms from authorities like the Central Pollution Control Board (CPCB), businesses must adopt effective emission control solutions. 

What is a DG Set RECD Device?

RECD stands for Retrofit Emission Control Device. It is an advanced filtration system installed in diesel generator exhaust systems to reduce harmful pollutants such as:

• Particulate Matter (PM)
• Carbon Monoxide (CO)
• Hydrocarbons (HC)
• Nitrogen Oxides (NOx)

DG sets, especially older models, emit high levels of particulate matter that contribute to air pollution. To address this issue, regulatory bodies have mandated the installation of RECD systems on certain categories of diesel generators.

An RECD device is installed externally to the existing RECD for DG Set exhaust system, which means there is no need to replace the generator itself. This makes it a cost-effective compliance solution.

Why Is RECD Required for DG Sets?

In cities facing serious air quality concerns, diesel generators are major contributors to pollution. Regulatory authorities require DG owners-particularly in commercial buildings, hospitals, residential complexes, and industrial facilities-to retrofit their generators with approved emission control devices.

The objective is simple:

• Reduce particulate emissions by up to 70–90%
• Improve urban air quality
• Ensure compliance with CPCB emission norms
• Avoid penalties and operational shutdowns
• 
  

Without a certified RECD system, DG set operators may face fines or restrictions during inspections.

How Does an RECD Work?

A Retrofit Emission Control Device functions by filtering exhaust gases before they are released into the atmosphere.

The typical working process includes:

1. Exhaust Entry – Polluted exhaust gases enter the RECD chamber.
2. Filtration Stage – A specialized catalytic filter or particulate filter traps harmful particles.
3. Oxidation Process – Some systems convert toxic gases into less harmful substances.
4. Clean Exhaust Output – Filtered gases are released with significantly reduced particulate matter.

Modern RECD units are designed to operate efficiently without causing excessive back pressure on the DG engine.

Benefits of Installing an RECD Device

Installing an RECD device provides several advantages:

• Legal compliance with emission norms
• Reduced environmental footprint
• Improved corporate sustainability profile
• Avoidance of penalties
• Longer DG system life due to controlled exhaust flow
• Increased property value in regulated urban areas
• 
  

For commercial complexes and IT parks, compliance is often mandatory for operational licenses.

1. Is RECD Mandatory for All DG Sets?

RECD installation is mandatory in specific regions and for certain DG capacities as defined by pollution control authorities. Requirements vary depending on state pollution control board notifications.

2. How Much Emission Reduction Can an RECD Achieve?

A certified system like the Aceget RECD Retrofit Emission Control Device System can reduce particulate matter emissions by up to 70-90%, depending on generator condition and load.

3. Does Installing an RECD Affect DG Performance?

When properly designed and installed, an RECD does not significantly impact performance. High-quality systems maintain safe back pressure limits to protect engine efficiency.

4. What Maintenance Does an RECD Require?

Routine inspection and periodic cleaning of filters are necessary. Maintenance frequency depends on DG usage hours and load patterns.

5. Can RECD Be Installed on Old DG Sets?

Yes. RECD systems are specifically designed for retrofitting older diesel generators without replacing the entire unit.

6. How Long Does Installation Take?

Installation typically takes a few hours to one working day, depending on DG size and site conditions.

Conclusion

Air pollution control is no longer optional it is a regulatory and social responsibility. Diesel generators remain essential for power backup, but their environmental impact must be managed responsibly.An RECD device offers a practical and cost-effective solution for emission compliance. Choosing a certified and high-efficiency system like the Aceget RECD Retrofit Emission Control Device ensures reliable performance, regulatory approval, and long-term sustainability. If your organization operates diesel generators in regulated zones, now is the right time to evaluate RECD installation and stay ahead of compliance requirements.
