The triple-coil heating element is designed with a three-ring coiled structure that provides compact installation, uniform heating, and enhanced heat transfer efficiency.
By coiling the heating tube into three concentric loops, the effective heating surface area increases significantly, allowing for rapid temperature rise and stable heat output in liquid or air heating applications.
The element consists of a high-resistance Ni–Cr heating wire embedded in high-purity magnesium oxide (MgO) powder, enclosed within a stainless steel, copper, or nickel–iron–chromium alloy sheath for excellent thermal conductivity and insulation performance.
This robust design ensures long service life, efficient energy conversion, and reliable operation under high-temperature or continuous-use conditions.
It is widely applied in water heaters, oil tanks, air heaters, and industrial heating systems requiring compact, high-efficiency heating performance.
