Diesel Generator (DG) sets play a critical role in providing backup power for industries, commercial buildings, hospitals, data centers, and residential complexes. However, while DG sets ensure uninterrupted power supply, they also contribute significantly to air pollution. With increasing environmental concerns and strict government regulations, controlling emissions from DG sets has become a necessity rather than an option. This is where the Retrofit Emission Control Device (RECD) becomes extremely important.
What is RECD for DG Sets?
A Retrofit Emission Control Device is an advanced pollution control system installed on existing diesel generator sets to reduce harmful exhaust emissions. RECDs are designed to trap and reduce particulate matter (PM), smoke, and toxic gases released during diesel combustion. These devices are especially crucial for older DG sets that were installed before the implementation of sentent emission norms.
RECDs are approved by regulatory authorities such as the Central Pollution Control Board (CPCB) and are mandatory in many regions to ensure compliance with emission standards.
Why DG Sets Are a Major Pollution Concern
Diesel engines emit a high level of pollutants, including:
Particulate Matter (PM2.5 and PM10)
Nitrogen Oxides (NOx)
Carbon Monoxide (CO)
Hydrocarbons (HC)
Prolonged exposure to these pollutants can cause respiratory diseases, cardiovascular problems, and severe environmental damage. In urban areas where DG sets are widely used during power outages, the pollution levels can spike rapidly, posing serious health risks.
Why install RECD for DG Sets?
1. Compliance with Government Regulations
One of the primary reasons to install a Retrofit Emission Control Device is regulatory compliance. Pollution control authorities have made RECD installation mandatory for DG sets operating in many cities and industrial zones. Non-compliance can lead to:
Heavy fines
Sealing of DG sets
Legal action
Suspension of operations
Installing RECD ensures that your RECD DG set meets emission norms and avoids regulatory penalties.
2. Significant Reduction in Air Pollution
RECDs are highly effective in reducing particulate emissions—often by up to 70–90%, depending on the technology used. By trapping soot and fine particles, a Retrofit Emission Control Device dramatically improves the quality of exhaust gases released into the atmosphere.
This reduction directly contributes to cleaner air, making a positive impact on both public health and the environment.
3. Protection of Human Health
Air pollution from DG sets affects employees, residents, and nearby communities. Fine particulate matter can penetrate deep into the lungs and even enter the bloodstream. Installing a Retrofit Emission Control Device helps minimize these health hazards, ensuring a safer environment for everyone.
This is critical especially for hospitals, schools, residential societies, and commercial complexes where people are constantly exposed.
4. Extension of DG Set Life
By controlling exhaust emissions and improving efficiency, RECDs can also help in reducing engine stress. Cleaner exhaust systems result in less soot accumulation, which can enhance the operational life of the DG set and reduce maintenance issues over time.
5. Improved Corporate Image and Sustainability
Organizations today are increasingly evaluated based on their environmental responsibility. Installing a Retrofit Emission Control Device demonstrates a strong commitment to sustainability and corporate social responsibility (CSR).
For industries and commercial establishments, this not only enhances brand reputation but also helps meet ESG (Environmental, Social, and Governance) goals.
How Does a Retrofit Emission Control Device Work?
A Retrofit Emission Control Device is installed in the exhaust system of a DG set. It uses advanced filtration and catalytic technologies to:
Capture ring
Oxidize harmful gases
Reduce visible smoke
Some RECD systems include Diesel Particulate Filters (DPF) or catalytic converters that regenerate automatically or manually to maintain performance without affecting generator efficiency.
Why RECD Is Important for the Future
As environmental regulations become more stringent, the importance of RECDs will continue to grow. Cities facing severe air pollution issues are enforcing stricter emission norms, and DG sets without RECDs may soon become obsolete.
Installing a Retrofit Emission Control Device is not just about compliance today—it is an investment in future-proofing your power infrastructure.
Surgery
DG sets are indispensable, but their environmental impact cannot be ignored. Installing a Retrofit Emission Control Device is a practical, effective, and responsible solution to reduce emissions, protect public health, and comply with environmental regulations.
Whether you are an industrial operator, commercial property owner, or facility manager, adopting RECD technology ensures cleaner air, legal compliance, and sustainable operations. In a world increasingly focused on environmental accountability, RECD is no longer optional—it is essential.
