What is my favourite task as Managing Director? When we master challenges effectively and make our customer’s processes more efficient with our products. This is a real pleasure for me, and it is what makes us successful.

Continuous development

Innovation

To provide you with the highest quality standards, we constantly develop our own products further, in collaboration with institutes and research facilities. As early as 1989, we introduced the original duplex filter, which combines two porosities in one filter. Other established in-house developments include the Ceralu® Al2O3 filter, the Cerazirk ®ZrO2 filter, the Cerapor® LDNG filter, and the Cerasic® SiC filter.

In the area of pre-cast ceramic shapes, Drache Fused Silica and Fused Silica Fine are two of our proven solutions. These materials are also manufactured in-house.

Future-oriented company

Sustainability

As a future-oriented company, it is important to us that our customers and working staff be treated with respect. A sustainable treatment of the environment and its resources is a top priority for us.

Emission and noise-level measurements are performed on a regular basis to protect the health of our employees and ensure compliance with German and European directives.

We are responsible and energy-efficient in our work. For Example, we use the excess heat of our large furnaces for other processes.
