The double-ended heating element is designed with heating terminals on both ends, allowing easy installation and efficient heat transfer in confined spaces.
It provides uniform heating performance, making it ideal for applications requiring stable and reliable heat output in water, oil, air, or solid heating systems.
Inside the tube, an Ni–Cr resistance wire is precisely positioned and insulated with high-purity magnesium oxide Nickel–Iron–Chromium Alloy powder. The generated heat is rapidly transferred through the stainless steel, copper, or nickel–iron–chromium alloy sheath to the target medium.
This design ensures fast heating, high efficiency, and long service life, even under high-temperature or continuous operation conditions.
Its double-ended structure enhances mechanical stability and electrical safety, widely used in industrial and household heating systems.
