Kipp Umwelttechnik receives an order to clean the SCR catalytic converters of a fleet operator and systematically develops the existing FilterMaster process further.

During cleaning, deposits of urea and other salts must be removed from the catalytic converter housing and the catalytic converter surfaces themselves. Several catalytic converter cartridges are installed in a housing that is fully sealed except for the inlet and outlet openings, making them difficult to access. Opening the housing for cleaning with subsequent welding was not permitted by the customer. Pure wet-chemical cleaning was not promising and undesirable due to the complex geometry and the partially insoluble salts.

After some preliminary tests, Kipp Umwelttechnik used a special version of the patented FilterMaster system. The SCR catalytic converter was cleaned completely and to the customer’s satisfaction. The cleaning costs amounted to only around 10% of the four-digit price of the new SCR catalytic converter.

The customer has now placed a framework order with Kipp Umwelttechnik for the cleaning of these SCR catalytic converters.

The new special version of the FilterMaster process used here is now available on the market.
