Wehrhahn solution will speed up the production cycle at Xella!

Wehrhahn was selected as a cooperation partner to provide Xella with a tailor-made solution.

With the brands Ytong and Hebel, Xella is one of the world's largest manufacturers of autoclaved aerated concrete (AAC). The Xella Group is in a stable market position - the continuous growth of the German construction industry also presents challenges for production. Driven by the market, Xella wants to increase its production volume, so the production process has been reconsidered. The identified options were checked with the following objectives:
· Highest potential
· Highest priority
· Avoid bottlenecks
· Best possible solution
· Return on investment
As a result of the factory inspection, Wehrhahn was selected as a cooperation partner to provide Xella with a tailor-made solution in order to achieve the desired increase in capacity and implementation as far as possible in parallel with ongoing production. The new customer-specific unloading solution optimizes the work in the unloading area in time and guarantees a smooth and quality-oriented unloading process.

Learning from similar upgrade projects makes us a qualified and valuable partner to review your production process as well - let us know how we can tackle your challenges!
