BGY8 Explosion-Proof Electric Heater
Inside the stainless steel heating tube, high-temperature resistance wires are evenly distributed. The gaps are densely filled with crystalline magnesium oxide powder, which has excellent thermal conductivity and insulation properties. This structure not only leads to high thermal efficiency but also ensures uniform heating. When current passes through the high-temperature resistance wires, the heat generated by the heating tube is dispersed through the crystalline magnesium oxide powder to the metal tube surface, and then transferred to the heated object or air, achieving the purpose of heating.
BGY4/BGY2 Stainless Steel Explosion-Proof Electric Heater is composed of heating elements, heater shell, bimetallic thermometer, exhaust valve, and volume expansion thermostat switch. The MI cable used in this equipment is different from ordinary tubular heaters; its shape is linear. The temperature difference between the heating cable's core and the metal sheath is very small, resulting in good thermal conductivity, reliable operation, and long service life. After the heating cable is formed by winding, the heat exchange area is large, the surface heat load is low, the heating is uniform, and the thermal efficiency is high. The heating element sheath is made of stainless steel and nickel-plated, providing good corrosion resistance. This series of heaters uses thermal oil as the heat transfer medium, adopts electric heating to raise the temperature, and is an efficient, energy-saving heating equipment that uses a high-temperature oil pump for forced liquid phase circulation. It is widely used in various fields.

Maintenance Measures:
a. Regularly clean the heater according to the actual working mode and the contamination level of the fluid. Use an appropriate cleaning solution to wash away muddy sediments, while solid sediments inside the components or in recesses need to be removed by disassembling the heating element assembly. To avoid damaging the heating elements or heater recesses, suitable solvents should be used for cleaning.
b. Only the conduit side of the heating element group can be cleaned with liquid cleaning agents or solvents.
c. After cleaning the heater, reassemble the heater in the reverse order of the above procedures, replace the new flange gasket, and test the heating elements.
