A Proven Controller for Active DPF


  • According to the 'Law for Improvement of Air in the Capital Area, 2003.12' and its Clause 8, the Minister of Environment must set up a plan every decade to reduce and improve air pollution in capital area. 

  • The diesel vehicles being out of warranty have to be installed DPF or be scrapped.

  • The act plan of the PHASE 1 had been carried out from 2005 to 2014 and PHASE 2 have been going since 2015.

What's DPF?

  • DPF (Diesel Particulate Filter) is a celluar structured trap filtering PM(Particulate Matter) from diesel exhaust in vehicle and convert PM to the no harmful substance by oxidizing with catalytic reaction.

  • Catalyzed DPF regenerates continuously with the aid of exhaust heat or heating system.

Role of DPF Controller

  • Active Regeneration DPF can regenerate filter even during driving with the aid of catalyst on filter and burner.

  • Burner system heats up exhaust gas and controls inlet temperature of DPF.

  • Safety regarded function are included; extinguish detection, misfiring, over heating of the filter.

  • It uses diesel in a fuel tank and regenerates periodically or when back pressure increases due to soot accumulation.

  • Logging & monitoring device records in the SD card.
