Product Description
Available in overall heights ranging from 50mm to 300mm, this spiral coil immersion heating element is engineered primarily for water boilers, commercial electric kettles, distillation tanks, and other compact liquid heating systems. The spiral immersion heater is constructed with a high-grade SUS304 / SUS316L stainless steel outer sheath, compacted with high-purity magnesium oxide (MgO) insulation and a heavy-duty NiCr resistance wire core utilizing advanced precision manufacturing processes. Its engineered helical spiral coil geometry significantly maximizes the active heat transfer area within limited vessel footprints. Key features include a space-saving profile, rapid thermal recovery, consistent heating accuracy, and an extended service life. Each unit comes standard with a stamped metal mounting bracket with high-temperature electrical isolation bushings and fast-on spade terminals to ensure quick installation and dependable electrical connectivity.
