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

The Nabertherm HTC high-temperature furnace is a “Made in Germany” all-rounder for the professional laboratory. Its durable **SiC rod heating** and very high heating speed make it a perfect choice for sintering technical ceramics. In fact, for some processes like sintering zirconium oxide, the SiC rods reduce chemical interaction and are more suitable than MoSi₂ elements.

These furnaces feature vertically hung SiC rods that heat from both sides. Furthermore, the high-quality, RCF-free fiber insulation and a long-life roof insulation provide for excellent energy efficiency. The construction is based on the proven HT product line, with a dual-shell housing, reinforced floor, and a parallel swivel door for operator safety.

Standard Equipment:

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

• Max Temperature: 1550 °C (Recommended working temp 1500 °C).
• SiC Rod Heating: Vertically mounted SiC heating rods for fast heat-up.
• Advanced Insulation: High-quality, multi-layer fiber insulation (RCF-free and non-carcinogenic).
• Parallel Swivel Door: A chain-guided, parallel swinging door opens downwards, so the hot face is always away from the operator.
• Reinforced Floor: Protects the bottom insulation and allows for loading heavy weights (distributed load 5 kg/dm²).
• Labyrinth Door Seal: Ensures the least possible temperature loss.
• 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.
• Stainless Steel Exhaust Hood: Includes an interface to your facility’s exhaust system.

You can upgrade your Nabertherm HTC furnace with a wide range of optional “Made in Germany” equipment for advanced processes and automation.

Available Options & Accessories:

• 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, but this is a typo in their data, Tmax is 1550°C).
  • Protected Heating Elements: Protection against mechanical damage.
  • 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.
