Retrofit Emission Technologies
Discover RAS & RECD
CHALLENGES
The Issue?
Emission Regulations
Tighter norms demand lower PM, CO & HC levels legacy gensets struggle to comply.
PM Output
Older engines release harmful PM that directly impacts air quality and health.
Manual Solutions
Usual cleaning, silencer fixes, offer inconsistent performance & frequent choking.
Maintenance & Downtime
Non-certified retrofits increase backpressure, reduce efficiency & create downtime.
Wastage & Costs
Unregulated combustion leads to wasted fuel & higher operating expenses.
Compliance Risks
Non-compliance leads to penalties, shutdowns in urban & industrial zones.
SOLUTION
Product Line
Cummins offers two purpose-built retrofit technologies engineered for clean emissions and long-term reliability.
PROCESS
How It Works

Engine exhaust enters a Diesel Oxidation Catalyst that breaks down CO and HC.

Exhaust then passes through a Particulate Filter, trapping fine PM particles.

Cleaned exhaust exits with emissions reduced up to 90%.

No fuel additives required and minimal impact on engine performance.

Exhaust enters the Electrostatic Precipitator chamber.

Charged plates attract and hold particulate matter without the use of filters.

No choking occurs, eliminating the need for cleaning or regeneration.

Collected PM can be reused as raw material in paints, dyes, plastics.
