Description

An explosion-proof heater with constant temperature

technical field

The utility model belongs to the technical field of explosion-proof heaters, in particular to an explosion-proof heater with constant temperature.

Background technique

Explosion-proof electric heater is a kind of consumption electric energy converted into heat energy to heat the material to be heated.
