BGY8 Explosion-proof Electric Heater Precautions:
1. The element is allowed to work under the following conditions:
A. Relative humidity of air not greater than 95%, without explosive and corrosive gases. (Except for explosion-proof heaters)
B. 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 fixed and positioned, 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 before reuse 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 only after the medium melts can it be raised to the rated voltage.
