Auer Lighting relies on advanced technology from HORN

Auer Lighting GmbH is a leading company in the lighting industry and is known worldwide for its innovations and high quality. Speciality glasses have been manufactured in Germany for more than 75 years. Auer Lighting's high-quality products are used in numerous industries such as automotive lighting, architecture and medical technology.

As a subsidiary of HORN, JSJ Jodeit received an order from Auer Lighting in May 2023 for a new hybrid furnace for the plant in Bad Gandersheim. The order included the furnace with three forehearths and a transition to existing forehearths. 

With a melting area of 19.1 m², the hybrid furnace is designed for a total melting capacity of approx. 20 t/d of borosilicate glass. It is cross-fired as a natural gas and oxygen furnace and is equipped with direct electric boosting.

To support both the melting process and the refining of the glass, several additional electric boosting systems (HORN E-Fusion Power Boosting) are installed in the bottom of the melting tank. This means that the maximum pull rate can be melted particularly flexibly with both 100% fossil energy and up to approx. 30% electrical energy. 

With the commissioning of the new all electric glass melting furnace, another important step has been taken towards production with lower CO2 emissions. This hybrid furnace is an example of adapting to changing market requirements while at the same time improving performance. The furnace operator can now react extremely flexibly to energy price fluctuations by shifting the proportion of electrical energy while maintaining the same high glass quality. 

The new furnace was built and commissioned from mid-June to mid-August 2024 under the supervision of JSJ Jodeit. Thanks to the excellent cooperation with Auer Lighting, the entire project was successfully completed within the specified schedule and the new 20 t/d hybrid furnace was commissioned on time.
