exciting projects, useful information and some topics of our own – please enjoy reading!
Wehrhahn Teeyer Smart Technology Corp. Ltd. established in China
After being the number one European equipment supplier for AAC and fibre cement in China for more than 20 years, we are pleased to announce our cooperation with Teeyer from Changzhou.
The joint venture company ‘Wehrhahn Teeyer Smart Technology’ was established to complement the key equipment supplied by Wehrhahn from Germany in projects where customers intend to procure the equipment specified as ‘local’ or ‘buyer’ supply through a reputable single contractor. It enables Wehrhahn together with the Joint Venture company to offer cost-attractive turnkey solutions to customers around the globe.
Our partner Teeyer from Changzhou is a listed company with an excellent reputation in the Chinese market. Prior to the establishment of the joint venture, the parties realized several projects. Wehrhahn supplied the key equipment from Germany and Teeyer completed the ‘local’ delivery according to Wehrhahn's drawings and specifications.
Deeper co-operation in the form of a joint venture is now the logical consequence.
Customers who are interested in such cost-efficient turnkey solutions are cordially invited to contact us!
We invite you to visit us at the bauma Munich 2025!
Curious to learn everything about latest developments in the autoclaved aerated concrete (AAC) and fibre cement industry? Come and visit us at the bauma Munich from 07 - 13 April 2025. Happy to welcome you in hall C1 at booth 339.
Autoclaved aerated concrete (AAC) and fibre cement are in great demand. Our sales team invites you to learn all aspects of these two outstanding building materials and the associate world class production process.
Visit Wehrhahn, the one and only solution provider for autoclaved aerated concrete (AAC) and fibre cement sheets production!
2nd Production plant for PVA fibre reinforced corrugated sheets in Sri Lanka
El Toro from Sri Lanka is already a well-known brand for high-quality autoclaved sheets. Now the second production plant for PVA fibre reinforced corrugated sheets is in operation.
The new production plant is equipped with all the latest Wehrhahn innovations. The most recent sheet thickness control system enables highly feasible production conditions and significantly reduces the carbon footprint of the production process. Another innovation is the highly flexible waterjet cutting system, which is implemented in a corrugated sheet plant for the first time.
We would like to thank the entire El Toro team for their excellent cooperation on this project!

Wehrhahn presentation at the IIBCC 2024 in Colombo (Sri Lanka)
The IIBCC 2024 was an excellent venue with a superlative programme and great speakers covering a wide range of topics.
Our fibre cement specialist, Rainer Becker, gave a presentation on „Sheet thickness control system optimization through mathematical modelling and self-learning pump maps“.
Intelligent control systems are a vital part in all Wehrhahn production plants. In fibre cement sheet production plants the automatic sheet thickness control system has a decisive influence on the plant performance and feasibility.
A general issue with sheet thickness control is the linked structure of the various controllers involved for tank filling levels, slurry throughput, felt speed and slurry density. Time lag and mutual dynamical influences can lead to increased sheet thickness tolerances under certain operating conditions such as plant start-up or e.g. in the event of process disturbances by changes in flocculation efficiency or increasing pipe clogging.
Here considerable improvements can be achieved.

Worldwide unique plant upgrade in Romania
The new edition of the AAC worlwide (04/2024) has been published.
The full article can be found here.
Read about the Wehrhahn project, which is a perfect example, that a strong partnership and trustful cooperation between our customer and us can realize ambitious goals and pioneering ideas even under most difficult conditions.
Worldwide unique precuring section for AAC production
For Elpreco SA in Romania, Wehrhahn upgraded the aerated concrete block production plant to a capacity of 1,900 m³/day. The existing mixing plant with the travelling mixer was replaced through the most efficient Wehrhahn mixing system including the advanced WECOMIX electric control system.
The smart conversion of the outdated “crane-operated” precuring section has challenged Wehrhahn to develop a worldwide unique technology in order to store the moulds at an elevated precuring chamber.
As a result, the highly advantageous system has fully eliminated numerous labour forces previously needed in the section and has reduced the precuring time as well as energy consumption significantly.
Finally, the cherry on top is the Wehrhahn Master Control Server (MCS). The smart system combines production data from all sections and provides the user with priceless information from production and energy management up to quality control and preventive maintenance.
What a success! IIBCC 2022
Thank you for everyone that met us this week at the IIBCC in Hamburg.
We really enjoyed the interesting talks and discussions and are looking forward to the next IIBCC!
