Wehrhahn celebrates 125th anniversary - reliable technology since 1892

Experience gathered over more than a century of producing machines for the manufacture of high-quality building materials for a wide variety of construction applications.
Starting 1892 - in the light of increasing industrialisation in Europe, when building materials of all kinds were in great demand, Wehrhahn today is at home all over the world and yet with strong roots. Wehrhahn technology made in Germany - we are proud of our 125 year's history!
The success story of Wehrhahn is at the same time the success story of our committed team. They are all highly trained and motivated and every day they advance the company a little bit further with their drive and expertise.
Constantly encouraged by clients who appreciate our top quality standards, reliable service and collaborative attitude.
On all continents Wehrhahn plants are in operation. Internationally leading manufacturers of fibre cement and AAC use Wehrhahn plants and technology.
Wehrhahn has been consistently successful in dealing with changing market conditions through continuity, stability and constant innovation – and can therefore look to the future with great optimism!

Wehrhahn advanced zero process related waste systems for AAC production plants
Part of the Wehrhahn "no system waste" concept is the patented Wehrhahn bed remover for tilt cake systems.
The bottom layer is recycled before the cake is being autoclaved.
In the past the hardened (autoclaved) bed could only be recycled in the process after being milled. With the Wehrhahn technology at least 4 % of raw materials can be saved and other process related disadvantages have been overcome.
All cake processing like tongue and groove cutting or handhold milling is done prior to autoclaving. As a consequence there is no process related AAC waste to be expected.
