Volvo, Mack Launch Reman Programs For DPFs

Posted on November 19, 2008

Volvo Trucks North America and Mack Trucks, both part of the Volvo Group, one of the world’s largest manufacturers of trucks, buses and construction equipment, diesel engines and drive systems for marine and industrial applications, announced that they have launched a large-scale program to remanufacture diesel particulate filters (DPF). The program for both manufacturers will operate out of the Middletown Remanufacturing Center (MRC) in Middletown, Pa.

The program enables Volvo and Mack customers to exchange the used ceramic filter element from their DPF for a clean one when service is required, reducing service time and simplifying emissions control systems maintenance. The DPFs are remanufactured to more than 90% of original capacity, the two companies said, and are warranted.

According to Bob MacPherson, MRC’s manager of lean systems and new engine projects, a key advantage of the program is the ability to remanufacture in bulk, instead of servicing one filter at a time. “A DPF filter element is reusable,” MacPherson said. “When it’s no longer doing its job optimally, the component is sent to us and we return it to useful service. It’s a great deal for customers.”

The DPF cleaning process used by MRC was selected after a long search of available technologies. The companies said that testing showed the system is capable of removing more ash in one cleaning than other methods could in several cleanings and it can clean and remove ash from a fully plugged DPF. The system is also able to detect cracked filter elements during the cleaning process. The filter element is not subjected to high-pressure pulses that add additional stress, as with some other techniques, Volvo and Mack said.
