DPF-EB system

Diesel Particulate Filter with Electrical regeneration as a Basic model 

This system is a basic variant of the DPF-E system and has been specifically developed for use on smaller generators up to approx. 100 kW on mega yachts and for inland navigation and stationary applications. The maximum allowed quantity of sulphur in the fuel is 1000 ppm or 0.1% within this context. 

The DPF-EB system consists of a separate diesel particulate filter element, electric heater and control. The heater controller can be supplied with both an on/off soft starter or as a modulating model. 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 between 15 and 20 dB(A) as standard.

 

Options

The DPF-E system can be combined with an SCR-S system. The SCR system will be installed behind the DPF-E system within this context.

The following options can be supplied:

  1. Various coating types for diesel particulate filters
  2. On/off (soft starter) or modulating control
  3. Port mode
  4. Motor load signal through J1939 or analogue
  5. External communication through Mod or CAN bus.

 

DPF-EB system overview

Diesel Particle Filter system

The particle filter of this system are coated with a catalytic layer. The maximum allowed quantity of sulphur in fuel will depend on the selected catalytic coating. This coating ensures that the caught particulates oxidise at a lower temperature with oxygen. Without this coating, particulates would, after all, only combust at approximately 600 °C. The type of catalytic coating is aligned with the engine type, load profile and the required hydrocarbon reduction by our engineers 

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. This is the reason why the DPF-EB has electrical regeneration.
