The Flowtech Diesel Oxidation Catalysts, or DOCs, can be a lifesaver when it comes to reducing emissions from diesel engines and equipment. Whether you’re driving a heavy-duty vehicle, maintaining a fleet, or powering an industrial generator, DOCs specifically designed for types of diesel can help cut down on dangerous emissions.
Not only are they simple and cost-effective, but they’re also maintenance-free and effective at reducing Carbon Monoxide, Hydrocarbons, and Diesel Particulate Matter.
Applications of Diesel Oxidation Catalyst (DOC)
The DOC’s technology is constantly expanding thanks to its effectiveness when compared to other methods of emission reduction.
Advantages of Using Diesel Oxidation Catalyst (DOC)
To reduce emissions without investing in costly engine upgrades. It’s also possible for DOCs to be installed alongside other control systems, such as particulate filters or exhaust after-treatment systems, to further reduce emissions.

Flowtech offers two universal-fit configurations for the Diesel Oxidation Catalysts (DOCs), which are demonstrated in the images below. The welded (one-piece) design is the ideal option for space-limited applications being more compact. Alternatively, the clamped design is easy to remove the centre-body (catalyst) for inspection and cleaning, if required. This makes the system friendly for maintenance, repair, and replacement.
