High-Temperature Bottom Loading Furnaces up to 1700 °C

The electrically driven lift-bottom considerably allows for proper charging of the high-temperature furnaces LHT/LB. The heating all around the cylindrical furnace chamber provides for an opitimal temperature uniformity. For high-temperature furnace LHT 02/17 LB the charge can be placed in charge saggars made of technical ceramics. Up to three charge saggars can be stacked on top of each other resulting in a high productivity. Due to its volume the high-temperature furnace LHT 16/17 LB can also be used for applications in production.
