Heater Protection Tube


Because of its excellent high temperature performance, silicon nitride ceramic has become the first choice material of the electric or gas heater’s protective tube.

Due to its excellent high temperature resistance and strong thermal shock resistance, silicon nitride ceramic product can withstand the heat load of a high temperature heating element or burner for a long time, and the service life is up to more than one year;

Silicon nitride ceramics hardly react with the aluminum liquid, so it will not pollute the aluminum liquid, which is conducive to improve the purity of aluminum liquid under high temperature;

Compared with the traditional upper radiant heating method, its energy efficiency can achieve 20%-30%, and it effectively avoids the aluminum liquid at the upper side to be excessive oxidation.
