Mining-CRT® systems

The need to reduce particulate matter (PM) emissions from mining machines is necessary, driven by new regulations and an increasing understanding of detrimental health effects of exposure to fine particles.

The best solution for particulate emissions reduction is particulate filters. Systems such as the DPFi system have been successfully employed in mining.

Johnson Matthey has developed a passively regenerating DPF system that is suitable for underground mining, as it does not increase NOabove engine-out levels.

The first part of the unit is the CRT® system, designed to reduce CO, HC and PM by more than 90%. This is followed by a decomposition catalyst to bring the NOdown to the levels required.
