ActivCRT® and ActivDPF ® diesel particulate filters
ActivCRT® and ActivDPF® diesel particulate filters
The Johnson Matthey ActivDPF® automatically regenerating DPF system ensures that your emergency genset is always ready to generate clean power.
The ActivDPF system integrates the patented CRT® system with a load bank for reliable filter regeneration, even where there is insufficient load for passive regeneration.
The ActivDPF system delivers the most cost-effective performance in the industry:
