Industry Applications
The applications our product data sheets actually name, on-road and off-road.
Where Our Parts Go
Deferry parts sit in two families of exhaust: engine exhaust, where a monolith carries a three-way, oxidation, SCR or particulate filtration function, and industrial exhaust, where a monolith carries a VOC catalyst or acts as a heat accumulation body.
On-road passenger, medium and heavy-duty vehicles
Substrates, coated catalysts and direct-fit converters for cars, vans, buses and trucks.
Stationary engines
Emission control for engines running in fixed installations.
Power generation
After-treatment for generator sets and gen-set emission systems.
Dust control
Particulate filtration where exhaust dust has to be captured.
Mining equipment
Diesel particulate filtration for equipment working underground and on site.
Construction
Off-road construction machinery running diesel engines.
Marine
Diesel exhaust after-treatment for marine engines.
Material handling
Forklifts and other handling equipment operating in enclosed spaces.
Diesel locomotive
Particulate filtration for rail diesel traction.
Industrial emission
VOC substrates and catalysts, SCR catalysts and heat accumulation substances for industrial exhaust purification devices.
Matching A Product To An Application
- Gasoline engine, on-road: ceramic or metallic substrate with three-way catalyst coating, or a direct-fit OEM converter.
- Diesel engine, on-road and off-road: cordierite or silicon carbide DPF substrate, catalysed DPF, diesel oxidation catalyst or SCR catalyst.
- Generator sets and stationary engines: converters and substrates sized to the engine displacement.
- Industrial exhaust: VOC substrate and VOC catalyst, and heat accumulation substance for regenerative units.
