With our proven cleaning method since 18 years it is possible to clean all diesel particulate filters, SCR catalysts and OXI catalysts.

In the thermal-mechanical cleaning process developed by us, the soot filters are freed from all residues (soot and ash) and, after cleaning, largely possess the technical properties of a new filter. One advantage of our gentle cleaning process is that the filter (housing) does not have to be opened and thus damage is avoided and the durability of the heat displacement mat is guaranteed. Using endoscopic camera technology, we can inspect the condition of the filter in the closed housing. With an air flow and weight measurement we measure the blockage/load of the filter.

The filters cleaned by us are cleaned as long and as often as necessary until they have been freed of approx. 98% of the soot and ash residues and have reached the reference value for the respective filter type. For this several cleaning processes are necessary.

The cleaning time therefore depends on the degree of contamination of the filter. In general, we need approx. 1-3 working days (Monday to Friday) for cleaning, but on average 80% of the filters are cleaned within 24 hours.

After successful cleaning, the filter is checked again and the measured values are recorded in our test report.

If your filter cannot be cleaned, you will not incur any cleaning costs!

Does your vehicle have an additional external catalyst in addition to the DPF? Please clarify this with your workshop, as the catalytic converter should also be cleaned.

Barten Garantie

TÜV tested cleaning process

TÜV Rheinland has tested our cleaning process for the flow characteristics of new, used and cleaned soot filters.

The test result from TÜV Rheinland is as follows:

Barten’s cleaning process restores the flow characteristics of used filters to comparable quality of new filters!

We give a 6-month guarantee on our cleaning performance.

Chemical Cleaning – Problems and Disadvantages

In contrast to our gentle cleaning process, there is also chemical cleaning using a chemical liquid solution. However, this chemical solution can only burn the soot. The resulting ash remains in the filter and also blocks it. Soot filters which have reached the maximum loading condition due to their mileage are NOT suitable for chemical cleaning!

The subsequent soot filter was treated, for example, with a chemical cleaner. On the picture “inlet side” no damage can be seen and on the picture “outlet side” only white dots/impacts can be seen, which already indicate a fusion of the ceramic inside the filter. On the other pictures you can clearly see what the chemistry has done to the ceramic core. The honeycomb structure is fused, as temperatures of well over 1500°C are reached.

These can be the effects of a chemical pre-treatment! In our experience, such damage can occur with approx. 7 out of 10 filters. Our recommendation: Clean your soot filter professionally and gently as soon as the ash content is too high and the error message “DPF” appears!
