Wehrhahn supplies complete AAC plants or individual machines, depending entirely on specific requirements of its clients. Wehrhahn takes account of all the relevant factors and conditions, such as production quantities, location, space available, level of investment and much more.

Wehrhahn’s advanced, modular and versatile plant systems allow investors to select the best suited plant from a choice of AAC plant systems all formed by repositioning and combining the proven Wehrhahn machines in different sequences and positions.
