Retrofit Emission Control Devices (RECD) are generally better for older industrial diesel generators (125kVA+) to meet strict regulatory compliance, as they are specifically designed to reduce >70% of particulate matter and carbon monoxide. Diesel Particulate Filters (DPFs) are primarily for modern, smaller engines (vehicles/gensets) to trap soot, often requiring higher maintenance.

What is RECD?
It is a pollution control technology
installed on the exhaust system of
diesel generator sets to reduce
harmful emissions. These emissions
are involved, which are particulate
matter (PM), hydrocarbons (HC),
carbon monoxide (CO) and nitrogen
oxides (NOx).

What is DPF?
A DPF (Diesel Particulate Filter) is
an exhaust emission control device
in diesel vehicles that traps and
stores soot, reducing harmful
pollutants released into the air. It
acts as a ceramic filter in the
exhaust system.

What are the effects in
Environment?
The primary environmental effect
is the substantial reduction of air
pollutants, particularly in urban
and industrial areas, improving air
quality and reducing the carbon
footprint of diesel-dependent
operations.

Conclusion
At last we hope you understand the comparison between RECD
and DPF. We discuss key differences and similarities which clear
the aspects of these two systems. RECD is the system based
device and the DPF is the component based machine. These
systems also helps to control the environment and nature based
integrated system.
