Rath Group's Competence Center for hot gas filtration in Meißen, Germany has recently been equipped with further advanced test facilities and a second production line installed.
The second production line will enable Rath’s production capacities to be almost doubled to produce up to 80,000 innovative ceramic hot gas filter elements annually at the Meißen research and production site.
For many years, Rath has been developing innovative ceramic hot gas filter elements, which make it possible to filter particle-laden industrial flue gases at temperatures up to 1000° C and to reduce emissions of nitrogen oxides.
Since 2016, all resources, capabilities and know-how in hot gas filtration have been brought together in Meißen and this research and production site is home to facilities for the manufacture of Rath's FILTRATH hot gas filter cartridges and FILTRATHCAT catalytic filter elements.
The latter were developed for pollutant emission control: These rigid yet highly porous and catalytically coated ceramic filter elements are used for multiple pollutant control of (fine) dust, acid gases, dioxins and nitrogen oxides in hot gas flows (at temperatures of 250°-420°C) and can easily replace conventional textile filters.
With around 35 employees, the Hot Gas Filtration Competence Center is responsible for all research and development, including the laboratory and technical centre, as well as for quality assurance.
The technical department, which deals mainly with the design of filter systems and the entire process technology, is also located in Meißen.
“Where R&D is concerned, there are strong synergy effects between the site in Meißen and other production sites that produce and develop high-temperature insulation wool and vacuum-formed parts,” says Manfred Salinger, Director Advanced Ceramic Filtration Solutions.
In recent years, Rath's Meißen site has developed into an important hub for hot gas filtration:
“It’s at our competence centre that the entire filtration expertise is bundled and the further development of filter elements is initiated. Rath specialists from a wide variety of fields around the world draw on the knowledge that’s accumulated here,” Mr Salinger added.
Last year, the technical centre was equipped with test facilities that has enabled Rath to conduct complex investigations and tests at high temperatures.
“It's about testing filter elements for new applications, and simulating important functional parameters,” explained Mr Salinger.
Rath Filtration also has ambitious plans when it comes to production volume. Previously, around 50,000 filter elements were produced annually.
With the recently completed production line, capacity has been increased to around 80,000 units.
Also, thanks to the new production line, delivery times will be significantly shortened.
