Exhibitor Profile

HJS Emission Technology GmbH & Co. KG is a medium-sized company founded in 1976 and based in Menden in central Germany.

HJS has many years of experience and expertise in the field of exhaust-gas aftertreatment.

Some 450 employees are engaged in the development, production and marketing of modular systems for reducing pollutant emissions. These innovative environmental protection technologies can be used either as original equipment or for retrofitting in passenger cars, commercial vehicles as well as in a wide range of non-road mobile machinery and stationary applications. In addition to systems for spark-ignition engines, HJS today focuses on solutions for diesel engines – especially solutions for reducing the emissions of soot particles (particulate matter, PM) and nitrogen oxides (NOx). With its extensive portfolio of patents and cooperation with Germany's TÜV certification agency as well, HJS sets benchmarks internationally. The company's latest development is the patent-pending NOx system SCRT®TM with active thermal management.

SMF® - Innovative thin metallic filter media for industrial filtration applications

S. Steigert, K. Schrewe*, HJS Emission Technology GmbH & Co. KG, Germany

Learn more at FILTECH 2022 Conference

More than 2 million m² of HJS Sintered Metal Filter (SMF®) material have been produced within the last 15 years, with a peak production of 300.000 m² p.a.. The SMF® material is a thin (< 0.5 mm) porous sintered metal in which a precisely defined stainless steel powder is sintered with an expanded metal carrier. This results in a thin, mechanically and thermally very stable filter medium, which can be treated in further processing similar to sheet metal. The SMF® basis material is industrially manufactured as quasi endless sheet with a width of 125 to 130 mm. Approved for hot gas and exhaust filtration, the material is further processed into filter modules that are designed for the named applications.

These SMF® modules are proven for a very large number of exhaust gas filtration applications used by vehicle manufacturers for applications that are subject to the current European emission legislation and thus strict requirements for particle number reduction. Furthermore, there are first applications in the industrial filtration of gases. In addition to the thermal robustness of the filter material, the high retention capacity and good cleanability of inert filtrate is also a key factor.

The aim is to use the known advantages of the thin foldable SMF® material, such as sharp separation efficiency or good cleanability, for new industrial filtration applications...
