BGY2-220/3 Explosion-Proof Electric Heater
BGY2-220/3 Explosion-Proof Electric Heater Principle:
Explosion-proof heaters are generally used in hazardous locations where explosions may occur. Since the surrounding environment contains flammable and explosive oils, gases, dust, etc., contact with electrical sparks can cause an explosion. Therefore, explosion-proof heaters are required for heating in such occasions. The main explosion-proof measure of the explosion-proof heater is an explosion-proof device installed in the junction box to eliminate the risk of ignition by electrical sparks. Depending on the heating application, the explosion-proof rating of the heater varies and is determined on a case-by-case basis.
Technology:
The explosion-proof heating tube is composed of an explosion-proof heating tube and an explosion-proof junction box. The BGY2-220/3 explosion-proof electric heater uses a stainless steel heating tube with high-temperature resistance, in which high-temperature resistance wires are evenly distributed. The gaps are densely filled with crystalline magnesium oxide powder that has excellent thermal conductivity and insulation properties. This structure of the heating tube not only ensures high thermal efficiency but also uniform heating. When current passes through the high-temperature resistance wires, the heat generated by the heating tube diffuses through the crystalline magnesium oxide powder to the surface of the metal tube, and then transfers to the heated object or air, achieving the purpose of heating.
