Wehrhahn is exhibitor at “The Precast Show” in Indianapolis, Indiana (U.S.A.)

You are welcome to visit our team at the Indiana Convention Center, booth 140 from February 5th to 7th, 2025. We look forward to meeting you there!

In the U.S. Autoclaved Aerated Concrete (AAC) has found an additional use as cladding or fire protection on framed constructions. This suits well with the prevailing construction and has already opened a good future for AAC.

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 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The smart conversion of the outdated “crane-operated” precuring section has challenged Wehrhahn to develop a worldwide unique technology in order to store the moulds at an elevated precuring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
