The product quality issues of the electric heater itself and the unreasonable actual work of users may cause leakage accidents. The duct electric heater manufacturer summarizes as follows.
1. The electric heating tube of the duct electric heater is fixed and immovable. The reasonable heating plate must be completely immersed in liquid or metal solid, and empty burning is prohibited. If water or carbon contamination is found on the tube surface, it should be cleaned immediately and reused to avoid affecting heat dissipation.
2. When heating air, the components should be evenly arranged in a cross shape so that the components have good heat dissipation conditions, allowing the flowing air to be fully heated.
3. For heating easily soluble metals or solid salts, alkalis, leaching, paraffin, etc. Before the medium melts, the service voltage cannot be raised to the rated voltage.
4. Wiring components must be located outside the insulation layer to avoid contact with corrosive, explosive media and moisture. The wires must be able to withstand the long-term temperature and thermal load of the wire connection, and the wire connection screws should not be tightened with excessive force.
5. The magnesium oxide powder at the outlet of the heating tube of the duct electric heater should be protected at the use site to prevent leakage accidents.
