The particulate filters used by Emission Partner consist of a ceramic honeycomb structure through which the exhaust gases flow. Separation and filtration of the particles is achieved by forced flow through the porous channel walls of the filter substrate. The square channels are alternately closed for this purpose. The special channel structure and the thin intermediate walls result in a very high filter surface. This results in both optimum utilization of the reaction surface for oxidation of the soot particles and high storage capacity for ash residues.
A cordierite substrate is used as the filter medium for the system. The filter substrate is provided with a catalytic coating of precious metals and a highly active washcoat, which enable self-acting, passive regeneration from exhaust gas temperatures as low as 300 °C. The filter substrate is also provided with a catalytic coating of a highly active washcoat.
Depending on the application, the particulate filters are combined with silencers. Depending on the requirements, bypass dampers and their controls are needed. Emission Partner has developed its own control systems for this purpose.
The adaptation of the systems to different applications and performance classes is done by the number of particle filters.
