In the course of increasing energy efficiency at Ströher Group, Keramischer Ofenbau GmbH installed the energy-efficient heating system „EnerViT“ on a tunnel kiln for brick slips, legs, angles and façade cladding and carried out further measures to increase performance and reduce electrical consumption on the kiln. A challenging, extensive optimisation project, characterised by good teamwork between Ströher and Keramischer OFENBAU. Thanks to hard-working team members, happy faces and a positive mood at ignition and heating up of the tunnel kiln. Now, everyone is eagerly awaiting the energy consumption results after the commissioning is completed.
