Immersion heaters are ideal for heating liquids of all types in laboratory and industrial use. An immersion heater can offer safe, accurate heating of water, oil, solvents, and industrial gases. Certain immersion heaters are designed to allow them to hang over the edge of a vessel, and elements are contained in the coil section to concentrate heat at the bottom of the vessel. Heating elements are popularly made of polished stainless steel for superior performance and durability. Flanged immersion heaters feature U-shaped metal tubes brazen into a flange that optimizes heat transfer in an energy efficient way and can be used in various heating applications especially in pressurized vessels.
