DPF-S system

Diesel Particulate Filter with regeneration through a diesel burner

This high-end compact diesel particulate filter system has been specifically developed for use on generators on mega yachts and stationary applications were limited installation height is available. This system is very compact and has been designed to meet the high quality standards of the luxury yacht industry.

The DPF-S system consists of a stainless steel diesel particulate filter unit, diesel particulate filters, bypass valve, burner system and control. The control has standard data logging and extensive diagnostics (on-board diagnostics; OBD). Telemonitoring is offered as an option. We can offer remote service with this. The system replaces a silencer to a limited extent and will provide sound attenuation around 30 dB(A) as standard. 



The DPF-S system can be combined with an SCR-S system. The SCR system is installed behind the DPF-S system in this case.

The following options can be supplied:

  1. Additional silencer
  2. Intake and exhaust at alternative positions
  3. Alternative coating types for diesel particulate filters
  4. Port mode
  5. Motor load signal through J1939 or analogue
  6. External communication through Mod or CAN bus.


DPF-S system overview

Diesel Particle Filter System

With the DPF-S system the diesel particle filters are coated with a catalytic layer. This coating ensures that the caught particulates oxidise at a lower temperature with oxygen. Without this coating, particulates would, after all, only oxidize or burn at approximately 600 °C. The maximum allowed quantity of sulphur in fuel will depend on the selected catalytic coating. The type of catalytic coating is aligned with the engine type, load profile and the required hydrocarbon reduction by our engineers. The maximum allowed quantity of sulphur in the fuel is 2000 ppm or 0.2%

The temperature of the exhaust gases is usually insufficient to post-burn the particulates in the filters completely because generators are often loaded relatively low.

The Xeamos SFB burner system ensures that the exhaust gases are regularly heated so that the diesel particulate filter stays clean. The burner and bypass have been integrated together very compactly where the hot gases of the burner are mixed intensively with the exhaust gases close to the diesel particulate filter elements. This ensures that we can regenerate at a high temperature; up to 600 °C. This ensures that regeneration is always reliable including with regard to sulphur-containing fuel and high particulate matter emissions of the engine.
