Cartridge / Insertion Heaters

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


Description: two types  1)95 alumina ceramic sheath ,

 the heating core is made from RE(rare earth), High temperature reached 1400 ℃ 


2)Using the silicon molybdenum ceramic, filling with ceramic powder and sintering them under the high temperature, tube diameter Φ 10mmwhat 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.
