Air pollution has become a serious concern in many cities, especially where diesel generators are widely used during power outages. To control harmful emissions from these generators, the RECD (Retrofit Emission Control Device) has been introduced as an effective solution.
A RECD (Retrofit Emission Control Device) is an emission control system installed in existing diesel generators to reduce the release of harmful pollutants such as particulate matter (PM), carbon monoxide (CO), and hydrocarbons (HC). Instead of replacing the entire generator, this device is retrofitted into the exhaust system to significantly lower emissions.
In regions with strict environmental regulations, installing an RECD (Retrofit Emission Control Device) is often mandatory for diesel generator sets above certain capacities. This makes it an essential upgrade for industries, commercial buildings, hospitals, hotels, and residential complexes that rely on backup power systems.
What is RECD (Retrofit Emission Control Device)?
The RECD (Retrofit Emission Control Device) is a pollution control technology designed specifically for diesel generators. It is fitted into the exhaust line of a generator to trap and reduce harmful particulate matter before it is released into the atmosphere.
The primary goal of the RECD (Retrofit Emission Control Device) is to reduce emissions by up to 70–90%, depending on the type of device and generator capacity. It works using advanced filtration and catalytic processes that capture soot particles and convert harmful gases into less harmful substances.
This technology allows organizations to continue using their existing generators while complying with environmental guidelines and improving air quality.
How RECD (Retrofit Emission Control Device) Works
The RECD (Retrofit Emission Control Device) operates through a combination of filtration and catalytic oxidation. The device is installed in the exhaust pipeline of the diesel generator.
Here is how it works:
- Exhaust Gas Entry – Polluted exhaust gases from the diesel generator enter the RECD system.
- Filtration Stage – A specialized filter traps particulate matter (PM), which includes soot and tiny carbon particles.
- Catalytic Conversion – Harmful gases such as carbon monoxide and hydrocarbons pass through a catalyst that converts them into less harmful compounds.
- Clean Exhaust Release – The treated exhaust gas is then released with significantly reduced pollutants.
This process ensures that the generator operates efficiently while maintaining lower emission levels.
Benefits of Installing RECD (Retrofit Emission Control Device)
Installing an RECD (Retrofit Emission Control Device) offers several environmental and operational benefits.
1. Significant Pollution Reduction
The device can reduce particulate emissions by up to 90%, making diesel generators much cleaner.
2. Compliance with Environmental Regulations
Many government authorities require generators to install emission control systems. An RECD (Retrofit Emission Control Device) helps meet these regulations.
3. Cost-Effective Solution
Instead of replacing old generators with new low-emission models, businesses can install an RECD system at a lower cost.
4. Improved Air Quality
Reducing harmful emissions improves the surrounding air quality, benefiting employees, residents, and communities.
5. Extended Generator Life
With proper maintenance, the installation of an RECD (Retrofit Emission Control Device) does not negatively impact generator performance and can help maintain engine efficiency.
Where RECD (Retrofit Emission Control Device) is Required
The RECD (Retrofit Emission Control Device) is commonly installed in locations where diesel generators are heavily used.
Typical installations include:
- Commercial buildings
- Hospitals
- Hotels
- Shopping malls
- Manufacturing industries
- Residential societies
- Data centers
- Construction sites
These locations often rely on backup power, making emission control essential to maintain environmental compliance.
Maintenance of RECD (Retrofit Emission Control Device)
Like any emission control system, the RECD (Retrofit Emission Control Device) requires regular maintenance to ensure optimal performance.
Maintenance typically includes:
- Periodic inspection of filters
- Cleaning or replacement of particulate filters
- Checking for exhaust leaks
- Monitoring backpressure levels
- Ensuring catalytic components function properly
Regular servicing ensures the system continues reducing emissions effectively.
Future Importance of RECD (Retrofit Emission Control Device)
As environmental awareness increases and governments enforce stricter emission standards, the demand for RECD (Retrofit Emission Control Device) systems is expected to grow.
Cities facing high pollution levels are encouraging industries and building owners to retrofit their generators with emission control devices. In the future, installing an RECD (Retrofit Emission Control Device) may become a standard requirement for diesel generators across many sectors.
