20w Cartridge Heater

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

Description: Applying  for the air heating, Characteristic of high temperature and high power density , similar as the bolt heater, heaters for the aluminum mold, tube diameter will be ≥Φ 16mm. 

we take the process of  armoured and hollow  improving the traditional process of single heat radiating into double heat radiating, increasing the heat exchange capacity, reducing the heat saving to avoid the high working temperature damage the heating elements . What improve the life span more than 3 times than before.
