COMPARISON OF DPF CLEANING METHODS

OXYHTECH DPF CLEANER MACHINEHEAT TREATMENTULTRASONICS TREATMENTCHEMICAL ADDITIVES
DESCRIPTIONPut the filter on the work-top of the washing machine and connect it to the water / air pipe.Then you can perform a differential pressure measurement, and suddenly pressing a button the machine starts automatically to clean the filter.Cut the DPF and put it into an oven that gradually reaches 1100-1300°F burning the carbon residuals. Then weld the DPF.Dip the DPF into an ultrasonic tank full of water. The ultrasonics form micro-bubbles inside which the temperature is very high and the pressure reaches 500 atm. The implosion of the bubbles causes the detachment of the particulate matter from all of the filter substrates.Put the chemical additives into the vehicle tank together with the fuel in order to melt the burning residuals inside the engine and to eliminate them through the exhaust pipe.
TIMEFrom 30 minutes (car DPF – FAP) to 60 minutes (Truck DPF)8-12 hours
Pneumatic cleaning: 90 minutes
Oven-baking: from 8 to 48 hours
12-24 hours
ultrasonic cleaning + drying + pneumatic cleaning

Additive
There is a wide range of addivites; price change according to the manufacturer and to the channels of sale (from 20€ to 200€)
ADVANTAGES/ DISADVANTAGESTotal Removal of PM10 residuals
Removal of oil residuals
Removal of cerium residuals
Efficient cleaning of all of the types of particulate filter and catalyst (cars and heavy goods vehicles, also SCR) of every size.
Safety of the filter
Preservations of the noble metals of the DPF
Easy, fast and cheap
Removal of most of the PM10 deposits
Risk of damaging the integrity of the filter because of the cutting and welding
Melting of the cerium with the filter walls due to the high temperature
Risk of thermal shock that can damage the noble metals
Deep cleaning of the filter cells
Poor efficiency on very dirty filter (oil) and big-sized filters
Risk of damaging the filter due to the vibrations generated by the ultrasonics and the implosions of the bubbles
High water consumption (need to change it often to eliminate the PM10 cleaning residuals which deposit at the bottom.)
Easy and cheap
Ineffective: residuals are not actually eliminated and more are added to those generated by the additive itself, going to block further the particulate filter at long term.
