Ai RTF1200Ā series top-open tube furnaces feature the famousĀ KanthalĀ (Sweden) spiral wire coils embedded inĀ Mitsubishi (Japan) high-quality grade 1500 alumina fiber insulation. A double-walled steel internal housing helps minimize heat loss to the exterior surface.

Furnace operation is controlled byĀ EurothermĀ multi-segment digital controller, allowing the user to connect to a PC for remote control and monitoring of the furnace.


  • Top-open furnace chamber for fast and easy tube access.
  • Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
  • Multiple atmosphere processes in a single cycle are possible (ex: binder burn out in air and parts sintering under rough vacuum or inert gas environment.)
  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • Built-in computer interface.
  • Long life type K thermocouple.


  • Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions.
  • Power failure protection resumes furnace operation right after the point of failure when power is reestablished.
  • Limit switch turns off furnace once top is open.

Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
