High-Temperature Furnaces with Molybdenum Disilicide Heating Elements and Fiber Insulation up to 1800 °C

Due to their solid “Made in Germany” construction and compact stand-alone design, the Nabertherm HT Series furnaces are perfect for laboratory processes where you need the highest precision. In fact, their outstanding temperature uniformity (up to +/- 6 °C) and practical details set unbeatable quality benchmarks. These high-temperature furnaces are also perfectly suited for annealing titanium in medical applications or sintering technical ceramics.

The furnace features heating from two sides via high-quality **Molybdenum Disilicide (MoSi₂) heating elements**. Furthermore, the furnace uses multi-layer, RCF-free fiber insulation for low energy consumption and a reinforced floor (on models HT 16/16 and up) for heavy charges.

Standard Equipment:

Every HT series furnace includes these premium “Made in Germany” features:

• Max Temperature: Available in 1600 °C, 1750 °C, or 1800 °C versions.
• MoSi₂ Heating Elements: High-performance heating from two sides, protected against mechanical damage.
• Advanced Insulation: High-quality, vacuum-formed fiber plates (RCF-free and non-carcinogenic) for low energy use.
• Parallel Swivel Door: A chain-guided, parallel swinging door opens downwards, so the hot face is always away from the operator.
• Door Seal: A high-quality labyrinth seal ensures minimal temperature loss.
• Durable Floor: A reinforced floor with a SiC plate (on models HT 16/16 and up) protects the bottom insulation.
• Advanced Venting: A vapor vent in the roof with a motorized exhaust air flap, controlled by the program.
• Advanced Controller: Comes standard with the powerful **P570 controller** (50 programs, 40 segments each).
• Data Recording: Includes NTLog Basic for recording process data via a USB flash drive.
• Floor-Standing Design: Models N 31/H and larger include a base frame (smaller models are tabletop).

You can upgrade your Nabertherm HT furnace into a highly specialized system for any advanced thermal process, including debinding or operation under gas.

Available Options & Accessories:

• Debinding Safety Package: A comprehensive package compliant with EN 1539 for processes that release flammable hydrocarbons (e.g., debinding technical ceramics).
• Advanced Cooling: A fan system to cool the furnace with a defined temperature gradient.
• Atmosphere Control:
  • Protective Gas Connection: A connection to purge the furnace with non-flammable process gases (note: not gas-tight).
  • Gas Supply Systems: Available as manual or fully automatic systems.
• Advanced Door Systems:
  • Lift Door: An optional automatic lift door.
  • Automatic Door Lock: Includes a door contact switch for process safety.
• Chamber Modifications:
  • Refractory Brick Floor: For a higher floor load (Tmax 1700 °C).
  • Special Heating Elements: E.g., for Zirconia applications.
  • Thermocouple Inlet: A port for TUS measurements or charge control.
• Process Control Software: Integrate your furnace with the powerful VCD software package for comprehensive, PC-based process control, monitoring, and documentation.
