Glow plugs are heat transfer elements commonly used in heating and insulation applications. Here are some of their advantages:

High efficiency: Glow plugs heat up quickly and have high thermal efficiency, providing the required heat in a short period of time.

High controllability: Precise temperature control is achieved by controlling the current flowing through the glow plug, making them suitable for applications with high temperature requirements.

Simple structure: Glow plugs are generally simple in structure, easy to install and maintain, and relatively low in cost.

High safety: Glow plugs are relatively safe to operate, generally do not produce any harmful gases or chemicals, and are not prone to safety issues such as explosions or fires.

Versatile: Glow plugs can be manufactured in various sizes and shapes to meet specific needs, making them suitable for a variety of industrial and domestic applications.
