- Johnson Matthey DPFi electrically regenerating diesel particulate filter received CSA certification for use in Canadian underground mining and tunnelling.
- DPFi also holds certifications from Canmet Materials and VERT and has US approval from MSHA.
- Designed for light-duty diesel vehicles such as the Toyota Land Cruiser, the system regenerates electrically by connecting vehicles to external power underground.
- Electrical regeneration avoids high-exhaust-temperature cleans and surface trips, maintaining filtration performance and reducing downtime.
Certifications
Johnson Matthey's DPFi electrically regenerating diesel particulate filter has been certified by the Canadian Standards Association (CSA) for underground mining and tunnelling, and holds additional certifications from Canmet Materials and VERT; it is also approved by the US Mine Safety and Health Administration (MSHA).
Technology
The DPFi regenerates electrically rather than relying on high exhaust temperatures, enabling consistent filtration performance and preventing filter blockages associated with thermal regeneration.
Operational benefits
Electrical regeneration lets drivers connect vehicles to an external power source underground, eliminating the need to surface for regeneration, reducing downtime and helping maintain cleaner air throughout shifts.
Vehicle compatibility
The system is designed for light-duty diesel vehicles such as the Toyota Land Cruiser and can be adapted for other diesel vehicle types.
