Diesel particulate filter cleaning

What we offer:
There are a number of companies on the market today offering DPF cleaning. With the introduction of Euro VI, functional testing has become a core competency for filter reconditioning. This requires a comprehensive understanding of the system, and expertise concerning the aftertreatment of exhaust gases. Without this expertise or testing technology, irreparable damage to the DPF or the efficacy of its coating could go unnoticed, resulting in high costs.
In stark contrast to all other methods (water, CO2, chemical cleaning) cleaning with air presents no such risks. It must simply be utilized correctly if it is to achieve the efficient cleaning required for Euro VI particulate filters.
Our patented and globally unique cleaning and testing methods have become the benchmark for the industry.

Functional Testing of DPF and Catalytic Converters

What we offer:
The introduction of Euro VI emission standards entailed new demands in testing technology. We have developed the testing methods with these demands in mind, integrating 100% functionality testing into our process. Back pressure testing and flow behavior determination are not enough: Euro VI requires the testing of particulate retention; the catalytic reactivity – that is, efficacy – of the filter coating determines filter functionality.

Testing of Catalytic Reactivity:
Effectiveness and aging of the catalytic coating of platinum metal or vanadium coated filters

Testing of Particle Capture Rate:
Particle counter to ensure the required substrate filtration efficiency and Euro VI compliance

Fully-automated DPF cleaning & testing machine

What we offer:
HFSpace®: The first fully automated compact cleaning system for diesel particulate filters

At the 2016 IAA Commercial Vehicles fair in Hannover, Hirtenberger Filter Services is showing the first fully automatic compact filter cleaning system, HFSpace®, which lets garages and fleet operators economically clean diesel particulate filters themselves.
