BGY8 Explosion-proof Electric Heater Precautions:
1. The element is allowed to work under the following conditions:

A. The relative humidity of the air is not more than 95%, and there is no explosive or corrosive gas. (Except for explosion-proof heaters)

B. The working voltage should not exceed 1.1 times the rated value, and the shell should be effectively grounded.

C. Insulation resistance ≥1MΩ Dielectric strength: 2KV/1min.

2. The electric heating tube should be properly positioned and fixed, and the effective heating area must be completely immersed in liquid or solid metal. Dry burning is strictly prohibited. If scale or carbon deposits are found on the tube surface, they should be cleaned promptly to avoid affecting heat dissipation and shortening service life.

3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., the operating voltage should be reduced first, and then raised to the rated voltage after the medium melts.

4. When heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation conditions and allow the flowing air to be fully heated.

5. When heating nitrates, safety measures should be considered to prevent explosion accidents.

6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture; the lead wires should be able to withstand the temperature of the wiring part and the heating load for a long time. When tightening the wiring screws, avoid excessive force.

7. The elements should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, they can be dried in an oven at about 200°C, or heated by reducing the voltage until the insulation resistance is restored.

8. The magnesium oxide powder at the outlet end of the electric heating tube should be protected from pollutants and moisture in the use environment to prevent leakage accidents.
