How to reduce the risk of using cast copper heaters

Improper operation of heaters can pose safety risks. Below, we'll briefly share how to reduce the risks associated with using cast copper heaters.

First, consider the permitted operating conditions for cast copper heaters, including relative humidity greater than 95%, the absence of explosive or corrosive gases, voltage not exceeding 1.1 times the rated value, and reliable grounding. Insulation resistance ≥ 1MΩ, providing a sound foundation for safe operation. Secondly, cast copper heaters should be properly positioned and flowed. The effective heating area must be partially immersed in liquid or metal. Dry heating is strictly prohibited. If scale or carbon deposits are found on the tubes, they should be removed immediately before use to prevent heat dissipation and extend service life.

When heating fusible metals or solid nitrates, alkali tar, paraffin wax, etc., the operating voltage should be reduced until the medium has melted before returning to the rated voltage. When heating air, the components should be evenly spaced to provide optimal heat dissipation and ensure sufficient heating of the air flowing through them. The wiring of cast copper heaters should be placed in an insulated layer to avoid contact with corrosive, explosive media, and moisture. The lead wires should be able to withstand the temperature of the wiring and the heating load. Avoid excessive force when tightening the terminal screws.

In short, proper operating procedures are crucial to prevent damage to the equipment and ensure proper operation. The above are some precautions for safe use of cast copper heaters, and we hope you will take them seriously.
