The multi-form coiled heating element is specially designed with multiple regular coil configurations to achieve compact structure, efficient heat transfer, and uniform temperature distribution.
It can be customized into various shapes such as spiral, serpentine, or multi-loop forms according to the installation requirements of different equipment.
Inside the tube, a high-resistance Ni–Cr heating wire generates heat, which is conducted through high-purity magnesium oxide Nickel–Iron–Chromium Alloy insulation powder to the stainless steel, copper, or nickel–iron–chromium alloy sheath.
This design ensures excellent thermal efficiency, durability, and mechanical strength, suitable for continuous operation in industrial environments.
The multi-coil structure maximizes surface area for faster heat exchange, making it ideal for large-capacity heating systems or irregular heating zones.
