Built with quality

Ai TFM3 series 3-zone tube furnaces are manufactured for quality and durability. The furnace hearth is built with Mitsubishi (Japan) high quality fiber materials. A high-precision Shimade fp93 temperature controller maintains temperature with +/-1 °C accuracy and 40 programmable segments. The furnace housing keeps the furnace housing at a safe, low temperature with double-layer steel and two built-in cooling fans. And because the furnace tube is sealed by stainless steel vacuum sealing flanges, the TFM3 series can be used under vacuum conditions.

All TFM3 tube furances are CE certified.

Top-notch heating elements

  • The 1200°C model (#TFM3.1200) is manufactured with Kanthal resistance wire from Sweden. Kanthal wire is renowned for trouble-free production thanks to its consistent resistivity.
  • The 1700°C model (#TFM3.1700) is built with SiC and MoSi2 heating elements. These quality heating elements allow the unit to reach its high temperature.

Computer connectivity

The Ai TFM3 series units feature a built-in USB/RS485 interface for connecting to a computer. A software & cable kit is provided with each purchase. The software allows you to control the temperature and other parameters from a Windows PC. Historical performance can be recorded for later study and reference.

Safety features

  • Furnace overheat protection cuts off power when temperature is over the desired range.
  • Thermocouple protection cuts off power when the thermocouple is broken or malfunctioned.
  • Temperature variation protection cuts off power when the difference between actual temperature and target temperature is off the desired range. (refer to controller’s manual)
  • Power failure protection resume furnace operation right after the point of failure when power is back up.
  • Stainless steel flange support makes sure the tube and flanges are secure and in their absolute position, it also longer the life of the tube.

Warning! Never fill the furnace with explosive gases. This includes hydrogen, carbon monoxide and methane.
