Ultrasounds are sound waves with frequencies above the human auditory range (20 – 100 kHz). The ultrasound applications are based on the physical phenomenon of cavitation which may be induced in any liquid medium. The sound waves cause the microscopic bubbles present in the natural liquids to expand (during phases C and D of high pressure). The formation and implosion of bubbles (cavitation process) is produced thousands of times per second.

Yes

Yes, there has been many instances where we have been able to restore filters that other service centers with traditional cleaning equipment claimed were irrecoverable.

This program is being developed and we hope to have available very soon for some of the very popular filters.

Yes we do. Contact our team for more information

We would like to offer this service however space does not permit at this time.

1. Though the process of continual thermal cycling in the DPF (Regeneration), with each soot burn off there is a residue of inert ash.   When this gets mixed with humidity and heat from the exhaust this ash gets baked and impacted into the filter.   Over a period of time, by performing the simple ‘pin test’, it will be found that the filter is filling and back pressure is increasing

2. There has not been sufficient regeneration and the filter has become plugged with soot

Yes – Periodic cleaning of DOC’s required otherwise these can become soot loaded and their effectiveness compromised – especially if the DOC has been exposed to high-sulfur and poisoned.

Ultrasounds are sound waves with frequencies above the human auditory range (20-100 kHz). The ultrasound applications are based on the physical phenomenon of cavitation which may be in any liquid medium.

The sound waves cause the microscopic bubbles present in the natural liquids to expand (during phases A and B of low pressure) and contract until they implode (during phases C and D of high pressure). The formation and implosion of bubbles (cavitation process) is produced thousands of times per second.

Ultrasonic cleaning is required to break down the impacted ash residue that traditional high temperature baking and air blasting could not break down. Where traditional cleaning could typically only get the filter 65-70% clean, with ultrasonics we can restore the filter to 98% clean.

Combination of flow test and pin test.   With the Pin test, a thin wire is inserted into the clean side of the filter and a measurement taken.  The Pin is then inserted into the ‘dirty’ side of the filter and a 2nd measurement taken. If the filter has been properly cleaned/restored then the 2 measurements should be equal.

Our equipment is big enough to clean all known DPF sizes.

Typically 24 hours.  A high speed cleaning program is being developed, watch this space!  There is the occasional filter that is very highly impacted and additional time is required.

Not a problem.  There is an additional charge for removal of sensors.  While we seek to be able to reuse these sensors, they are very sensitive and sometimes require replacing.  The DPF Company can supply these with your restored filter.

No – study by Tech Sonic International showed no loss in weight of filter/DOC as a result of cleaning
