Cleaning particulate filters

Diesel particulate filters can become clogged with too much soot, especially if the vehicle is only driven short distances.

Chemical cleaning agents do not work reliably, so replacement is usually the only option. However, replacement particulate filters are very expensive. A cheaper and equally effective solution is thermal-mechanical cleaning, i.e. “burning out” the filters. To do this, the filters are removed and completely heated slowly to around 600°C in a furnace. The soot burns off almost completely, and the remaining ash residues can be removed by blowing them out. Depending on the degree of soiling, heating may be repeated several times; in most cases, the process is successful after a maximum of 24 hours.

Similarly, thermal-mechanical cleaning of catalytic convertors can be employed when their catalytic behavior changes and the reaction time of the catalytic converter is prolonged because the converter surface is covered by a layer of soot.

Of course, Kittec also offers suitable furnaces for thermal-mechanical cleaning of particulate filters and catalytic converters. In this context, we would like to refer in particular to our model series CB, X and XR, as well as to our bogie hearth furnaces of the CTH model series.

Depending on the application, we can also develop completely individual solutions for you. Our special construction experts will be happy to advise you individually and help you find a suitable solution from our large product range.
