Advantage:
1.Cartridge heaters is consist of a cylindrical stainless steel tube and thus provide a high corrosion prevention.
2.Compatible with Creality CR-10S Pro,CR-X,Ender 3, Ender 3X, Ender-3 Pro 3d printer, etc
3.The number of coils varies depending on the power, and provide a great uniform distribution of heat,
which considerably increases the long life of the heater as well as prevents the oxidation of the heater wire even at high temperatures
4.The solids, liquids, and gases need to be heated by cartridge heater, transmit heat quickly by conduction if the producer of the heat (the cartridge) is in direct contact with the heat sink (any solid, liquid, or gas)
