SAVEDRY® is a measuring system which continuously evaluates moisture content of refractory. Leaks in the cooling system of the furnace can be reliably detected and located if water encroaches into the refractory material. In addition, the drying process of linings can be permanently controlled to optimize furnace up-time. Danger due to overheating (by burner) or residual moisture (premature termination) can be avoided.


The extraordinary flexibility of the technology enables the adaption to many customized tasks.

Application examples:

+ Arc furnace
+ Ladle
+ Graphitization furnace


The electrical resistance is dependent on the moisture content at the sensor location. The display of the current moisture content appears as a percentage on a separate bar graph for each segment. Excessive lining is indicated by additional optical signals. There are several types of sensors available that are specifically selected for the measurement task and the monitored aggregate.


  • Significantly improves safety

for operating staff and plant, because furnace damage and molten breakouts can be safely avoided

  • Optimize operating costs

by reducing the costs of maintenance and production losses

  • Increase equipment up-time

based on the risk-free increase of service life and predictability of relining

  • Targeted melting process improvement

by optimizing the sinter heat
