RECD-Retrofit Emission Control Device For DG Sets: Price, Benefits
Air pollution has become a major concern in many cities, especially in regions where diesel generator (RECD for DG set) are widely used as backup power sources. To control harmful emissions from DG sets, regulatory authorities have made it mandatory to install RECD (Retrofit Emission Control Device) systems on older diesel generators.
If you operate a diesel generator for commercial, residential, or industrial use, understanding RECD price, installation requirements, and benefits is essential to stay compliant and reduce environmental impact.
This guide explains everything you need to know about RECD (Retrofit Emission Control Device) for DG sets.
What is RECD (Retrofit Emission Control Device)?
A RECD (Retrofit Emission Control Device) is an emission control system installed on existing diesel generator sets to reduce harmful pollutants released into the atmosphere.Diesel generators emit particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons. These pollutants contribute significantly to air pollution. The RECD (Retrofit Emission Control Device) works by filtering and treating exhaust gases before they are released into the air.
RECD systems are mainly installed on older DG sets that do not meet modern emission standards.
Why is RECD Mandatory for DG Sets?
Environmental authorities introduced RECD (Retrofit Emission Control Device) regulations to reduce air pollution caused by diesel generators.
Key reasons include:
-
Reduction of Particulate Matter (PM) emissions
-
Compliance with government emission norms
-
Improvement in air quality in urban areas
-
Safe operation of older diesel generators
-
Avoidance of penalties or operational restrictions
Many cities now require DG sets above a certain capacity to install a RECD (Retrofit Emission Control Device).
How Does RECD Work in DG Sets?
The RECD (Retrofit Emission Control Device) is installed in the exhaust system of a diesel generator.
It typically includes:
-
Diesel Particulate Filter (DPF)
-
Catalytic converter
-
Oxidation catalyst
-
Exhaust monitoring system
When the DG set runs, the exhaust gases pass through the RECD (Retrofit Emission Control Device) where pollutants are captured or converted into less harmful gases.This process significantly reduces particulate emissions, sometimes by 70–90% depending on the system type.
RECD Price for DG Sets
The RECD (Retrofit Emission Control Device) price depends on several factors:
-
DG set capacity (kVA)
-
Technology used in the RECD system
-
Installation requirements
-
Brand and manufacturer
-
Exhaust system configuration
Approximate RECD Price Range
These prices usually include equipment, installation, and basic compliance testing.
Benefits of Installing RECD (Retrofit Emission Control Device)
Installing a RECD (Retrofit Emission Control Device) offers several environmental and operational benefits.
1. Reduced Air Pollution
The main advantage is the significant reduction in particulate emissions from diesel generators.
2. Regulatory Compliance
A RECD (Retrofit Emission Control Device) helps businesses comply with pollution control regulations and avoid legal penalties.
3. Extended DG Set Usage
Instead of replacing older generators, installing RECD allows continued use while meeting emission standards.
4. Better Corporate Sustainability
Companies using RECD (Retrofit Emission Control Device) systems demonstrate environmental responsibility.
5. Improved Air Quality
Lower emissions contribute to healthier surroundings for employees, residents, and communities.
Who Needs to Install RECD?
The RECD (Retrofit Emission Control Device) requirement usually applies to:
-
Commercial buildings
-
Hospitals
-
Hotels
-
Shopping malls
-
Industrial facilities
-
Residential societies
-
Data centers
Any facility operating older diesel generators may be required to install a RECD (Retrofit Emission Control Device).
RECD Installation Process
Installing a RECD (Retrofit Emission Control Device) typically involves the following steps:
-
DG Set Assessment – Evaluation of generator capacity and exhaust configuration
