»2 Expert II – cost-effective determination of the chamber start

»3 Conversion of the S5 control to S5/S7 components

The thermal processes in kilns and dryers are essential factors in the operation of a production plant. In the manufacture of ceramics, the product quality as well as energy consumption are strongly dependent on the design of the process systems. The considerate management of resources, sustainability and the reduction of CO₂ emissions are significant features resulting in lowered and optimized cost of operation on the one hand and, at the same time, in a contribution to environmental protection.
