India’s ongoing efforts to curb air pollution, regulations around diesel generator (DG) emissions have become stringent. One critical compliance requirement is the installation of Manufacturers Retrofit Emission Control Devices (RECD) for diesel generators manufactured. These devices help legacy DG sets meet environmental norms set by the Central Pollution Control Board (CPCB) and the National Green Tribunal (NGT), reducing harmful emissions without replacing the generator.
In this blog, we’ll explore RECD technology, spotlight Aceget Private Limited as a leading manufacturer in India, and answer common questions about CPCB-approved emission control solutions.
What Is a RECD and Why It Matters
A Retrofit Emission Control Device (RECD) is an advanced filtration and catalytic system fitted to existing diesel generators to significantly reduce emissions of:
Particulate Matter (PM)
Hydrocarbons (HC)
Carbon Monoxide (CO)
Nitrogen Oxides (NOx)
The device combines technology like Diesel Oxidation Catalysts (DOC) and Diesel Particulate Filters (DPF) to filter pollutants and convert harmful gases into less damaging substances before they exit the exhaust.
The installation of RECDs has become mandatory in India for DG sets in non-attainment areas under the National Clean Air Programme (NCAP). This is part of broader CPCB and NGT directives to improve urban air quality and public health.

Frequently Asked Questions (FAQ)
Q1. Is RECD installation mandatory in India?
Yes CPCB and State Pollution Control Boards mandate RECD installation for DG sets (up to 800 kVA and above) in many polluted regions under NCAP and NGT orders.
Q2. What emissions does a RECD reduce?
RECDs reduce particulate matter (PM), hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) by up to ~96% under optimal conditions.
Q3. Will RECD affect generator performance?
Properly installed CPCB-approved RECDs do not negatively affect engine performance or fuel efficiency.
Q4. How long does RECD installation take?
Installation typically takes 2–4 days, depending on DG size and configuration.
Q5. What is the cost range for RECDs?
Prices vary depending on capacity and features, typically ranging from approximately ₹2.5 Lakh to over ₹16 Lakh or more.
Q6. Do you provide service across India?
Yes leading manufacturers like Aceget offer nationwide service and technical support.
