Retrofit Emission Control Device (RECD) for Diesel Generators
Advanced Emission Control for Diesel Generator Sets
A Retrofit Emission Control Device (RECD) is an advanced pollution control system designed to reduce harmful exhaust emissions generated by diesel generator sets (DG sets).
Installed in the exhaust line of existing generators, the device significantly reduces pollutants such as Particulate Matter (PM), Carbon Monoxide (CO), Hydrocarbons (HC), and Nitrogen Oxides (NOx). The system allows organizations to improve environmental performance without replacing existing generator infrastructure.
RECD systems are engineered for seamless retrofitting and can be integrated with most diesel generators used for backup power in industrial, commercial, and institutional facilities.
Greenshield Enviro provides reliable emission control solutions that help organizations reduce air pollution, improve environmental performance, and operate generators more responsibly.

Why RECD is Important
Diesel generators are widely used across industries, commercial buildings, and infrastructure projects for reliable backup power. However, diesel exhaust contains particulate matter and other pollutants that contribute to air pollution.
Installing a Retrofit Emission Control Device helps organizations:
- Reduce particulate emissions from diesel generators
- Improve air quality around facilities
- Reduce visible smoke and soot emissions
- Support environmental sustainability initiatives
- Improve environmental responsibility of operations
Emission control technologies enable cleaner operation of diesel generators while maintaining operational reliability.
Key Features
High Efficiency Emission Reduction
Advanced filtration and emission control technologies capture particulate matter and reduce harmful pollutants present in diesel exhaust.
Retrofit Compatibility
RECD systems can be installed on existing diesel generators without requiring major engine modifications.
Industrial Grade Construction
Designed to withstand high exhaust temperatures and continuous generator operation.
Modular Installation
The system can be customized to accommodate different generator capacities and exhaust configurations.
Low Maintenance Operation
Automated cleaning mechanisms help maintain filtration efficiency and reduce maintenance requirements.
Reliable Performance
The device operates without affecting the performance or reliability of the generator.
How the RECD System Works
Exhaust Gas Entry
Exhaust gases from the diesel generator enter the emission control device installed in the exhaust pipeline.
Particulate Capture
Specialized filtration systems capture soot particles and particulate matter present in diesel exhaust.
Emission Reduction
Catalytic and filtration technologies reduce pollutant concentrations within the exhaust stream.
Clean Exhaust Release
Filtered gases are released with significantly reduced particulate emissions.
Emission Control Technologies Used
Retrofit Emission Control Devices may utilize multiple technologies depending on generator capacity and operational requirements:
- Diesel Particulate Filters (DPF)
- Catalytic Oxidation Converters
- Electrostatic Precipitator (ESP) based filtration systems
- Advanced soot filtration technologies
These technologies help remove particulate pollutants and improve overall exhaust emission quality.

- Reduction in visible smoke emissions
- Cleaner generator operation
- Continued use of existing diesel generators
- Improved environmental responsibility
Regulatory Compliance & Regional Applicability
Environmental monitoring and emission standards are regulated by authorities such as the Central Pollution Control Board and respective state pollution control agencies.
Facilities operating diesel generators must comply with environmental regulations enforced by authorities including:
- Delhi Pollution Control Committee (DPCC)
- Haryana State Pollution Control Board (HSPCB)
- Uttar Pradesh Pollution Control Board (UPPCB)
Adopting emission control technologies such as RECD can help organizations reduce generator emissions and improve environmental performance while maintaining reliable backup power systems.
