Emissions Services

Diesel Particulate Filter & Diesel Oxidation Catalyst Cleaning

Requirements for emission controls in the newest diesel engines make servicing the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) a necessity for any fleet or owner operator. Finding factory trained, knowledgeable service locations can be a challenge. D&W is dedicated to providing the best DPF and DOC refurbishing services in the market.

Pneumatic Cleaning Service

Through partnerships with industry leading DPF and DOC cleaning equipment manufacturers, D&W can offer the most comprehensive pneumatic cleaning service. All units are tested before service is rendered, tested again after a pneumatic cleaning and full documentation is provided.

Off-Vehicle Thermal Regeneration

When soot and ash need to be loosened in order for a pneumatic cleaning service to be affective, off-vehicle thermal regeneration or baking is needed. D&W has the capability to bake numerous DPFs and DOCs at once, returning the plugged units back to like new conditions.

Service History Database

With D&W’s DPF and DOC refurbishing services, not only are like-new units returned to you, also the service history of the units is recorded in our DPF and DOC database, eliminating yet more paperwork for fleet managers and owner operators to track. Should you ever need to know what the condition of a DPF was for a given vehicle at a given mileage or date of service, we can help.

On-Vehicle Services

Getting a DPF and a DOC off of a chassis and to a service center can be a hassle. D&W offers full range of on-vehicle services for everything from school busses to construction equipment. Our services include removing DPFs and DOCs for refurbishing services.
