Product Description

This double U‑shape heating element is a heavy‑duty tubular heater designed for high‑temperature air heating. Made of high‑temperature resistant stainless‑steel tube, it can operate continuously under high‑temperature conditions. Double‑U bent design provides larger heating surface. Thread‑type terminals allow quick installation. Voltage, wattage, tube length and bending size are fully customizable for industrial ovens, dryers and other hot‑air heating machines.

Material: Outer tube: SUS304 stainless steel Heating wire: Ni80Cr20 nichrome Filler: High-purity MGO powder Terminal: High temp ceramic + silicone gasket	Transport Package: Standard export carton with foam protection inside, each heater wrapped by plastic bag separately.
Form: Shape structure: Integral seamless multi-stack U-bend forming, split into short double U single-layer style and long multi-layer multi-bend high-power style, no welding seams on heating sections. Terminal structure: Dual independent threaded terminals with high-temperature ceramic insulation sleeves and silicone sealing gaskets, standard screw connector for quick wiring. Tube layout: Parallel stacked bent tubes to expand heating area, uniform heat radiation inside ovens.	Certification: CE, ISO9001, RoHS, CB, CCC
Shape: Main heating part: Continuous seamless bending into multiple stacked U loops, including single-layer double U small shape and multi-row long U-bend large shape. Terminal section: Two straight tube segments extend outwards separately, fitted with threaded mounting heads for installation. Smooth arc bends without sharp corners, uniform heat emission inside ovens.	Resistance Wire: Ni80Cr20 nichrome alloy resistance wire
