HIGH WATT DENSITY FIREROD HEATER

Technical features: the double-sided radiating will be instead of the traditional single radiating elements.

Two types:

  • 95 alumina ceramic sheath, the heating core is made from RE (rare earth), high temperature reached 1400 ℃.
  • Using the silicon molybdenum ceramic, filling with ceramic powder and sintering them under the high temperature, tube diameter ≥Φ 10mm, what can also be used in hollow tube with double radiating surface process, this process can make the elements long term working under the temperature ≤1400℃ with safety condition.
