The FIX STEIMEL® company was a medium-sized scale and plant builder from Hennef (Sieg). With the insolvency of the company in 2002, the gates of the company’s history closed for good after 78 years. From then on, we have secured the complete spare part supply and perform many modifications, modernizations, maintenance, and repair on FIX STEIMEL® plants. In 2006, we took over all technical documentation from the area of weighing and bagging technology and also secured ourselves the trademark rights of the FIX STEIMEL® name in 2007. As the original supplier, and thanks to the consistent archiving of all original work documents, we can thus continue to manufacture and supply spare parts in their original quality.
