Cartridge / Insertion Heaters

   Ceramic Heating Tube


Technical features: high temperature resistance, longer life span, applicable to the environmental temperature ≤ 1100℃

Description: two types  1)95 alumina ceramic sheath  the heating core is made from RE(rare earth), High temperature reached 1400 ℃ 

2Using 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.
