Diesel Oxidation Catalyst (DOC)
Off-Road

Technology That Works.
Our mix-and-match Diesel Oxidation Catalysts (DOC) are available in 4 standard diameters along with 22 different end cones.  This provides flexibility to fit a range of engines and applications and enables quick delivery for customers needing aftertreatment solutions. Our program is designed to provide DOCs for most off-road equipment installations including:

• Mobile and stationary equipment
• Rubber wheeled and rubber/steel tracked equipment
• Equipment used in ports, airports and construction
• Rental and non-rental fleets

Engineered for Performance.
The Cummins Emission Solutions diesel oxidation catalyst utilizes Johnson Matthey’s specially formulated platinum-based catalyst as a component of its product.
The DOC may either replace or be added to the existing vehicle muffler. Versatile and flexible, the DOC:

• Installs easily and is engineered for retrofit
• Available in standard sizes to cover a wide range of off-road applications
• Uses Johnson Matthey’s specially formulated platinum-based catalyst
• Needs no maintenance
• Can be used with low sulfur (<500ppm) or ultra-low sulfur (<15ppm) ) diesel fuels

*Standardized Cubic Feet per Minute.
Note: All substrates are 400 CPSI ceramic.
