A great piece of history  in craftmanship and industry

The “mechanical workshop of Wilhelm Wehrle”, founded in Emmendingen, Baden in 1860, has developed into an international active group of companies in energy and environmental technology:

WEHRLE-WERK AG is a medium-sized family-owned business with its subsidiaries WEHRLE Umwelt GmbH and WEHRLE BioEnergie GmbH in Emmendingen and ECOTHERM AG in Switzerland.

Top-quality apparatuses and components for machine and plant construction are manufactured in the factory floors in Emmendingen.   

From planning through manufacturing and construction to servicing – everything from one source.
