When using coil heating elements, it is necessary to pay attention to safety issues, such as preventing the coil from overheating, preventing electric shock, etc. Meanwhile, for different application scenarios, it is necessary to choose appropriate heating elements and control methods to achieve the best heating and energy-saving effects.

A coil heating element is a heating element that uses current to generate resistance and heat through a coil, converting electrical energy into thermal energy. It is usually made of high resistance materials, such as nickel chromium alloy or iron chromium aluminum alloy. The shape of the coil can be linear, circular, or spiral, and the appropriate shape can be selected according to different application requirements.
