Diesel generators are used as backup power in construction sites, industries, commercial buildings, and hospitals. However, they emit harmful pollutants that contribute to air pollution, such as carbon monoxide, nitrogen oxides, and PM or particulate matter. Emission control devices for diesel generators can resolve this issue.

What is an Emission Control Device?

Emission control devices (ECD) reduce the emission of harmful pollutants from diesel generators' internal combustion engines (ICE), especially diesel engines, which emit a higher amount.

The government in India has made these devices mandatory alongside the DG sets to curb air pollution and improve the region's air quality standards.

Introducing RECD – Retrofit Emission Control Device

A retrofit emission control device (RECD) is prescribed for existing diesel generators and serves to mitigate their emissions. Compliance with environmental regulations has been easy for institutions and companies as RECD can be attached as add-ons, making them cheaper alternatives when handled with existing generators than built-in systems in new machines.

What are the Benefits of Using RECD on DG Sets?

Using a RECD for DG sets has various advantages. A few of them include:

• Decrease in Air Pollution: The primary function of RECD is to control emission limits of PM2.5, NOx, and CO.

• CPCB Norm Compliance: Conducting business in India requires emission control adapters to be placed on DG sets. Installing a RECD helps companies to comply with these norms.

• Cost-Effective Upgrade: With RECD, it is possible to upgrade a DG set without replacing the entire generator.

• Improves Air Quality: By reducing emissions, RECD helps improve a region's air quality, which benefits employees working in the area and the local communities.

• Sustainable Business Practice: Supports the organisation's green policies.

How Does RECD Work?

RECD clean the exhaust of diesel generators using advanced filtration and catalytic processes. Here is how the emission control device for the DG set works in detail:

• Filtration Stage: Particulate filters capture soot and suspended particles emitted from the exhaust system.

• Catalytic Reduction: The device uses catalysts to break down harmful substances and transform them into harmless substances like nutrients and water, like nitrogen and water.

• Monitoring System: A few RECDs are equipped with sensors and control units that track performance and emission control.

Installation and Compatibility

RECDs are considered to have one of the best features due to their wide-ranging compatibility with almost all diesel generators. They are upgradable to diesel generators from 15 kVA to 1250 kVA or more. They may require only a few hours of installation with minimal changes to the pre-existing system. Additionally, most suppliers provide somecustomisationn for your specific DG set.

Government Regulations and Mandates

In India, the CPCB and the National Green Tribunal have been vigilant about the unchecked emissions from Diesel Generating Sets (DG Sets). As per some of the latest guidelines:

1. RECD installation is mandatory in several states for DG sets above 125 kVA.

2. Usage of non-compliant DG sets can result in fines or legal action.

3. Environmental clearance for buildings often depends on emission compliance.

As such, the scope of work for combustion engine emissions systems does need to include fugitive emission systems.

Choosing the Right RECD

These are some of the recommendations when considering a Retrofit Emission Control Device for your Diesel Generator Set (DG Set):

• Regulatory compliance: Look for approval of the RECD by CPCB at a minimum.

• Efficiency: Target devices with emission reduction capabilities ranging from 70% to 90%.

• Durability: These devices require minimal maintenance due to the highly durable materials and design.

• After Sales Support: Supporting the maintenance and tracking of performance enables installers to manage workflow optimally. Choosing a supplier who provides these services is essential.

Industries That Use RECDs

Several industries tend to gain financially from the installation of emission control devices on DG sets, including:

• Healthcare and hospital facilities

• Manufacturing units

• Construction companies

• Advanced learning centres

• Commercial malls and IT parks

• Hotels and commercial buildings

These sectors rely on an uninterrupted power supply to meet environmental compliance requirements. RECD make this balance possible.

Conclusion

Stricter government policies and concern for air pollution have made emission control devices for diesel generators inevitable. Not only do businesses fulfil their legal obligations by installing a RECD, they also contribute positively towards the environment.

RECD is the ideal solution for every diesel generator user due to their advanced technology, emission reduction efficiency, and easy installation. Go beyond expecting penalties and switch to a sustainable DG set today.
