Active DPF with burner assistant regeneration (DPF-BU) Stationary emissions control: A fuel burner will be used to regenerate the filter when the machine has stopped operating. Air from a small pump is heated to >600°C and blown through the filter to remove the carbon.
Active DPF with electrical regeneration (DPFi) Stationary emissions control: These systems use mains electrical power. The regeneration units may be mounted on the machine as an on-board control system, wall mounted or as an off-board control system.
Active DPF with exchangeable filter system (DPF-C) Stationary emissions control: These systems follow the same principle as the DPFi. The difference is that the electrical heater is in a stand-alone regeneration station and not inside the filter unit itself.
Backpressure monitor/data-logger (PIO-CAN) Stationary emissions control: The PIO-CAN monitor and data logging unit provides a graphic display for operating data and error messages. It measures, logs and displays exhaust temperature, backpressure and engine speed in up to five languages, plus more.
Catalysed soot filter (DPF-CSF) Stationary emissions control: As an alternative to the CRT® and CCRT® systems, it is possible in some applications to use a DPF system in which the catalyst is on the filter and no pre-catalyst is used.
Continuously regenerating trap DPF-(C)CRT® Stationary emissions control: These systems are normally suitable for use with a wide range of non-road mobile machinery (NRMM), engine power ranges and engine emissions levels.
Fuel borne catalyst (DPFiS) Stationary emissions control: This system uses air to burn the carbon in the filter. An additive is dosed into the fuel and passes through the engine to be deposited on the filter.
Johnson Matthey DPF-CRT® and DPF-CCRT technology for diesel emissions Stationary emissions control: Johnson Matthey Continuously Regenerating Technology (CRT®) System reduces PM, CO and HCs from diesel emissions and utilises engine NOx to oxidise soot collected in the filter.
Mining-CRT® systems Stationary emissions control: 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.
SCRT systems Stationary emissions control: Johnson Matthey’s SCRT® technology combines the diesel particulate filter system, incorporating an oxidation catalyst, to control CO, HC and PM, and a SCR catalyst to reduce NOx emissions.
