News & Innovations

Wehrhahn Master Control Server

Investors who focus on high-quality products are known to place high demands on the quality of their production facilities and thus on the production process.

They naturally expect intelligent automation modules to be integrated into their production facilities.

This enables a smooth production process with easy operation and self-optimisation. It is achieved by data, that is collected during production proces.

It is then evaluated by algorithms and used to optimise the process control. Integrated as standard, the new generation of aerated concrete plants uses "smart" technology and produces more efficiently than ever before!
