​​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

Additional equipment

  • Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
  • Saggar for charging of up to three layers
  • Protective gas connection to purge with non-flammable protective or reaction gases
  • Manual or automatic gas supply system
  • Adjustable air inlet through the floor
  • Process control and documentation via VCD software package for monitoring, documentation and control
