High-Temperature Furnaces with SiC Rod Heating up to 1550 °C

High-temperature furnace HTC 40/16

Vertically mounted SiC rods and optional perforated air inlet tubes of the debinding system

Exhaust-air flap and charge thermocouple including a stand as additional equipment

The high-temperature furnaces HTC 16/16 - HTC 450/16 are heated by vertically hung SiC rods, which makes them especially suitable for sintering processes up to a maximum operating temperature of 1550 °C. For some processes, e.g. for sintering zirconia, the absence of interactivity between the charge and the SiC rods, these models are more suitable than the alternatives heated with molybdenum disilicide elements. The basic construction of these furnaces make them comparable with the already familiar models in the HT product line and they can be upgraded with the same additional equipment.

  • Tmax 1550  °C
  • Dual shell housing with fan cooling for low shell temperatures
  • Heating from both sides via vertically mounted SiC rods
  • High-quality fiber insulation backed by special insulation
  • Side insulation constructed with tongue and groove blocks provides for low heat loss to the outside
  • Long-life roof insulation with special suspension
  • Chain-guided parallel swivel door for defined opening and closing of the door without destroying the insulation
  • Two-door design (front/back) for high-temperature furnaces > HTC 276/..
  • Labyrinth sealing ensures the least possible temperature loss in the door area
  • Reinforced floor as protection for fiber insulation and to load heavy weights
  • Exhaust air opening in the furnace roof
  • Heating elements switched via SCR‘s
  • 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
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
