Catalytic Exhaust Products recently expanded its product line with high-performance diesel oxidation catalysts designed for off-road and heavy-duty fleets, supporting Tier 4 and Euro VI compliance.

1. Diesel Oxidation Catalysts (DOCs): DOCs reduce carbon monoxide, hydrocarbons, and particulate matter in diesel exhaust by oxidizing pollutants into less harmful gases, improving compliance with EPA and Euro standards for low-emission fleets.
2. Diesel Particulate Filters (DPFs): DPFs capture and remove over 90% of soot and fine particles from diesel engine exhaust, regenerating periodically and supporting 2025 retrofit programs for urban delivery and municipal fleets.
3. SCR (Selective Catalytic Reduction) Systems: SCR systems reduce NOx emissions by injecting urea into the exhaust stream, reacting on a catalyst to meet stringent Tier 4 and Euro VI NOx limits for heavy-duty fleets.
4. Catalytic Mufflers: Combining sound attenuation with emissions control, these units replace standard mufflers with an integrated DOC, making them ideal for retrofitting older diesel equipment in urban and industrial environments.
5. Air/Fuel Ratio Controllers: These controllers optimize combustion by adjusting the air-fuel mix to enhance fuel efficiency and emission reductions, crucial for lean-burn natural gas and diesel engines in fleet operations.
6. Low Emission Engine Retrofit Kits: These retrofit kits combine DOCs, DPFs, and SCR systems for comprehensive emission reductions, helping legacy diesel vehicles achieve compliance with 2025 clean fleet incentive programs.
7. Custom Catalyst Manufacturing: Tailored catalyst solutions for specialized engines or equipment allow fleets to meet region-specific emission regulations and operational needs while extending the service life of older assets.
8. Engine-Specific Catalyst Design Services: Technical teams assess your fleet’s engine specifications to design catalyst systems that ensure compatibility, minimize back pressure, and comply with federal and provincial emission rules.
9. Off-Road Vehicle Emissions Systems: Solutions developed for mining, construction, and agricultural fleets reduce diesel particulates and NOx emissions without disrupting equipment performance, supporting grant-eligible clean tech upgrades.
10. Exhaust Silencers with Catalysts: Dual-function units that combine noise reduction with emission control for fleets operating in noise- or emission-sensitive zones such as airports, rail yards, or urban construction sites.
