Immersion Heaters are electric heating elements designed to directly heat liquids such as water, oils, chemicals, and viscous fluids by immersing the heater into the liquid. These heaters are constructed with a metallic sheath housing a resistance coil insulated with high-purity magnesium oxide for efficient heat transfer. Available in flange-mounted, screw-plug, or over-the-side designs, immersion heaters are ideal for industrial and commercial liquid heating applications.
