Our innovative product - DPF Euro 6 Connection Adapter, is designed for diesel particulate filters used in trucks, buses, construction machinery and forklift trucks. The adapter is fully compatible with machines cleaning DPF in hydrodynamic method.
DPF Euro 6 filter is distinguished by the fact that its ceramic core is fully exposed on the exhaust side as well as on the inlet side. This type of DPF came to us relatively recently, with the emergence of exhaust emissions standard Euro 6.
In the U.S. this type of filters appeared much earlier because from the beginning of the 2000s. They are characterized by the fact that they have equal and flat flanges - the edge of the steel ring, as opposed to their European counterparts.
|Traditional cleaning methods|
European filter manufacturers have released DPF Euro 6 in steel housings with non-standard edges, such as steel clips, openwork flange, metal bracket. All such solutions make it difficult to fit them tightly into a traditional adapter. Additionally, the stream of liquid during washing does not act with the same force on the whole length and section of the particulate filter. As a result, the outer filter walls located closer to the filter housing are not as thoroughly cleaned as the central part of the filter, where the jet acts with the greatest force.
In the last few years, European manufacturers of DPF cleaning machines equipped their machines with an adapter, which was based on the shapes of filters from the USA. Unfortunately, these did not quite meet the expectations of European customers. Therefore, in Europe, along with the increase in demand for cleaning Euro 6 DPF, there was a need to create a connection adapter fully universal and tailored to the current market needs.
It is worth noting that currently in the European market, manufacturers of DPF machines are still offering the old type adapters, shaped like a flat plate, cone, or a steel structure with a pneumatic actuator.
For the first years of use, DPF Euro 6 filters did not give a sign of life, so there was no need for an innovative adapter. Since the beginning of 2019, more and more Euro 6 filters are going to cleaning services. Mostly this is due to the mileage of the vehicles themselves and the limited capacity of the filter.
Starting in 2020, OTOMATIC is the first and only company to offer its customers a dedicated Euro 6 connection adapter that fully complies with European standards.
The invention is covered by patent application No. P.432918 (see document >>>)
OBJECT OF THE INVENTION
The steel flange of the inlet side of the Euro 6 DPF is flat and has even edges, in contrast to its irregular outlet side. During washing, the flat flange allows the filter to be fully sealed from the inlet side of the exhaust gas, advantageously along the circumference of its flat and even edge. In the old generation adapters, the adaptor must be fitted and seal the outlet side, which is troublesome due to its irregular shape.
The subject of the patent is a technology characterized by the fact that we seal the inlet side of the filter instead of the outlet side, which is troublesome due to its irregular edges, using a patented pressure vessel. In order to ensure the flow of the cleaning medium through the filter, the inlet side must be sealed around the perimeter of the ring edge of the filter housing so that the cleaning medium cannot escape except through the filter cartridge.
The uniqueness of the invention lies in the fact that we have retained (fulfilled) the basic principle of the wet filter cleaning technology, i.e. feeding the cleaning agent first from the filter outlet side, with the difference compared to competitive solutions that we seal the filter from the inlet side and not, as all others, from the outlet side.
The closed circulation of the cleaning agent in the pressure chamber guarantees complete and even cleaning of all filter channels. In addition, when drying with hot air, we achieve a thermo-circulating effect instead of spot drying.
- one adapter for all types of Euro 6 DPFs from trucks
- Uniform cleaning of all channels of the ceramic filter insert
- Three times faster filter drying time after cleaning due to thermobarrier effect
- Two-way cleaning and drying process
- increased competitiveness in relation to users of traditional adapters
