The helical heating element is designed with a spiral coil structure that provides excellent heat transfer, compact size, and uniform temperature distribution.
Its helical configuration allows for increased surface area and improved heat exchange, making it ideal for applications that require high heating efficiency in limited space, such as water tanks, oil heaters, and air heating systems.
Inside the tube, a high-resistance Ni–Cr heating wire is precisely wound and insulated with high-purity magnesium oxide powder. The generated heat is rapidly conducted to the stainless steel, copper, or nickel–iron–chromium alloy sheath, ensuring efficient and reliable operation even under high-temperature or continuous-use conditions.
The spiral structure also enhances mechanical strength and vibration resistance, ensuring long service life and stable performance in demanding industrial environments.
