Continuous operation of most furnaces results in deterioration of the hard refractory hot face lining and will damage the backup insulation. Cracking and spalling of the hot face shapes and castable linings will exposure backup insulation to high furnace operation temperatures. The backup insulation will overheat and hot spots will occur, resulting in a shut down of the heater/furnace and a cooling down periode before actual inspection and repair will be possible. 

The Insulcon hotspot repair system will eliminate all those problems. In close co-operation with Harm Meijer BV, specially trained engineers will act immediately.
