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.
Ammonia slip catalysts Stationary emissions control: Johnson Matthey's advanced ammonia slip catalyst (ASC) improves NOx reduction at low NH3 slip to improve the overall SCR system performance.
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.
CRTdm diagnostic module Stationary emissions control: CRT®dm diagnostic module and 24 month data logger is installed on every CRT system.
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.
Compact selective catalytic reduction (ComSCR) Stationary emissions control: Johnson Matthey’s new ComSCR was developed for small to medium sized diesel and gas engines. ComSCR is the answer to the increasing demand for compact, highly efficient, all-in-one-systems.
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.
Diesel oxidation catalyst (DOC) Mobile emission controls: many diesel particulate filter (DPF) systems incorporate an oxidation catalyst, either as a coating on the filter or as a separate element.
