    ​​​High-Temperature Furnaces Lift-Bottom 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.

    • Tmax 1700 °C
    • High-quality molybdenum disilicide heating elements
    • Furnace chamber lined with first-class, long-life fiber material, unclassified
    • Outstanding temperature uniformity due to all-round furnace chamber heating
    • Furnace chamber with a volume of 2 or 16 liters, table with large floor space
    • Precise, electric belt drive with push button operation
    • Housing made of sheets of textured stainless steel
    • Exhaust air vent in the roof
    • Type S thermocouple
    • Switchgear with thyristor
    • Defined application within the constraints of the operating instructions
    • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
