SRY6-2 380V/6 Sheathed Tubular 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. 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 zone 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 then raised to the rated voltage only after the medium melts.
4. When heating air, the elements should be arranged crosswise and evenly.
