Here is going to introduce how to reduce the risk of using cast copper heaters.
1. The cast copper heating plate should work under the following conditions:
A. The relative dryness of the environment is not greater than 95%, and there is no explosive corrosive gas.
b. The working voltage should not be greater than 1.1 times the rated value.
c. Edge resistance ≥ 1MΩ, dielectric strength: 2KV/1min.
2. When heating fusible metals or solid nitrates, alkalis, lime, paraffin, etc., the operating voltage should be reduced first. After the medium is melted, the rated voltage can be reduced .
3. When heating the gas, the components should be crossed and evenly arranged, so as to provide better heat dissipation conditions, which makes the flowing gas heated fully.
4. Safety measures should be considered when heating nitrateso as to prevent explosion accidents.
5. The wiring part should be placed in the insulation layer to avoid contacting with corrosive, explosive media and moisture. The lead wire should be able to withstand the temperature and heating of the wiring part for a long time, and excessive force should be avoided when tightening the wiring screws.
6. The cast copper heating plate should be stored in a dry place. If the resistance is lower than 1MΩ due to long-term storage, it can be dried in an oven controlled at 200°C, or be heated by reducing the voltage until the resistance is restored.
