Retrofit Emission Control Devices (RECD) for Diesel Generators: A Sustainable Solution

In today’s rapidly industrializing world, diesel generator (DG) sets remain a crucial source of backup power for industries, hospitals, commercial complexes, and residential societies. However, the environmental impact of diesel generators has become a serious concern due to the emission of harmful pollutants such as particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons (HC). To address this issue, Retrofit Emission Control Devices (RECDs) have emerged as an effective and regulatory-compliant solution.

This blog explores the importance of RECDs, their working mechanism, benefits, and highlights how Aceget stands out as a leading manufacturer of RECD and diesel dual fuel kits in India.

Understanding Retrofit Emission Control Devices (RECD)

A Retrofit Emission Control Device (RECD) is an advanced pollution control system installed in existing diesel generators to reduce harmful exhaust emissions. Instead of replacing old DG sets which can be expensive RECDs offer a cost-effective and efficient alternative by upgrading the emission performance of existing equipment.

RECD systems are especially important in countries like India, where regulatory bodies such as the Central Pollution Control Board (CPCB) and National Green Tribunal (NGT) have mandated emission control norms for in-use diesel generators. These devices ensure compliance with environmental regulations while improving air quality.

How RECD Works

The working principle of RECD revolves around filtering and treating exhaust gases before they are released into the atmosphere. It typically incorporates advanced technologies such as:

• Diesel Particulate Filters (DPF): Captures and traps soot and particulate matter.

• Diesel Oxidation Catalysts (DOC): Converts CO and hydrocarbons into less harmful gases.

• Selective Catalytic Reduction (SCR): Reduces nitrogen oxide emissions.

As exhaust gases pass through the RECD system, harmful pollutants are either filtered or chemically converted into less harmful substances. Some systems also feature automatic regeneration, where accumulated soot is burned off to maintain efficiency.

Benefits of Installing RECD in Diesel Generators

Installing an RECD offers multiple environmental and operational benefits:

1. Significant Emission Reduction
   RECD systems can reduce particulate matter and harmful gases by up to 90–96%, depending on the technology and operating conditions.

2. Regulatory Compliance
   Ensures DG sets meet CPCB, NGT, and CAQM guidelines, avoiding penalties and operational restrictions.

3. Cost-Effective Solution
   Retrofitting is far more economical than replacing existing DG sets with new compliant models.

4. Improved Air Quality
   Reduces visible smoke and toxic pollutants, contributing to a healthier environment.

5. Enhanced Equipment Life
   By optimizing combustion and exhaust treatment, RECDs can improve engine performance and longevity.
