Problems Solved
What This Category Fixes
- A carrier that has to hold performance stability over a long service life
- Ash left after regeneration that has to be managed
- Black smoke and soot emitted from diesel engine exhaust
- Carbon monoxide and unburned hydrocarbons in diesel exhaust
- Diesel particulate matter that must be trapped to meet the emission limit
- Filter cracking under thermal shock during regeneration
- Matching the DOC volume to the engine displacement
- Pressure drop across the filter that penalises engine performance
- Rising pressure loss as the accumulated particulate layer becomes thicker

Industry Applications
Automotive and On-Road Vehicles
Three-way catalysts for gasoline vehicles, oxidation catalysts and particulate filters for on-road diesel, built on PRT ceramic and metallic carriers.
Off-Road Construction and Mining
Diesel oxidation catalysts and particulate filters for off-road construction and mining equipment, where duty cycles are long and regeneration management matters.
FAQ
Frequently Asked Questions
Which product in this category should I start with?
Tell us the engine displacement or flue gas volume, the target emission standard and the space available. Our engineers will point to the right item in this category.
Are these items stocked to the published tables?
The tables show the universal specification and size published by PRT. Confirm current availability by email before ordering.
Do you quote coated and uncoated parts?
Yes. PRT supplies bare substrates as well as coated catalysts, so both can be quoted against the same drawing.
