Our traditional company can look back on a long history: from its beginnings with the first product developments in 1880 to the founding of today’s THEISEN GmbH in the 1920s and its current international involvement – almost 145 years have passed since then in which THEISEN has supplied state-of-the-art engineering technology for gas cleaning systems.
Herewith our most important milestones:
1880
The history starts …
with the invention of some important developments/break-throughs by the company founder Eduard Theisen: For example the first process for the production of milk powder, as well as the development of the THEISEN Gas Washer for cleaning off gas from blast furnaces. At the end of 19th century it was already possible to use the cleaned gasses in the gas machines of the steel industry to generate electrical power.
1911
Hans Eduard Theisen takes over the business
After the passing of the company founder, his son Hans Eduard Theisen took over the business. In 1914 he relocated the fabrication to the factory Karl Saaler, today called EHT Werkzeugmaschinen GmbH. One section of EHT is dedicated for the building of the gas washers.
15 July 1926
Merger to „THEISEN GmbH München“
A merger of the firms Ed. Theisen, München and A.V.G. Allgemeine Vergasungsgesellschaft m.b.H to form a new company „THEISEN GmbH München“. The firm was located, where it still is to this day, at Friedrich-Herschel-Str. 25 in Munich.
The new firm incoporates a wide spectrum for the application of the Disintegrator: cooling, scrubbing and tar separation during the cleaning of process and synthetic gases.
1985
Establishment of TVT THEISEN
With the establishment of TVT THEISEN Verfahrenstechnik, new business ventures are exploited: recycling of solvents, ground water cleaning, adsorbtion and absorbtion plants for air emmissions and process water plants.
TVT developed plants for the reduction of emmisions of organic solvents with incorporated recycling of process materials for re-use.
1992
SHT Industrieanlagen GmbH is established
SHT Industrieanlagen GmbH is established to bundle the capabilities of the associated firms:
- Schubeis (Machine fabrication)<br>
- Hellingrath (process control engineering)<br>
- THEISEN (gas cleaning)<br>
The Theisen hot gas filter is developed for the rock wool furnaces and can accommodate temperatures up to 800°C.
