Cleaning of a DFP
EvacuBake™ is designed to facilitate the cleaning process of dirty filters. In some cases a filter may need to be baked due to high levels of wet soot, unburned hydrocarbons, etc. and must be baked in order to regenerate the soot to ash. The controller is programmed to ramp up the temperature at a rate that will not crack the substrate of the filter and holds the temperature constant for two hours to ensure a complete regeneration of the filter. The controller then automatically decreases temperature at a controlled rate to protect the filter’s substrate.
