           Immersion Heater
           An immersion heater is a fast, economical, and efficient method for heating liquids in tanks, vats, or equipment.
           Known as bayonet heaters, they have heating elements that can be directly inserted into a container of water, oil,
           or other material in order to heat the entire contents.
           By using the direct heat transfer of an immersion heater, liquids quickly reach the desired temperature. Made of
           bundles of tubing, immersion heaters can be mounted on the side of a container or submerged in the contents.
           Their heating coils transfer heat to the contents, which spreads throughout the container.
           Immersion heaters are a cost effective and ecologically sound method for heating material and provide a clean
           source of energy without leaving residual discharge or pollutants. In nuclear reactors, immersion heaters are used
           to keep heated water at a constant temperature for creating steam.
           Parts of Heater

           Rating plate:- The rating plate in an immersion heater typically provides important information about the heater’s
           specifications and electrical requirements.
           Such as-Manufacturer Information,model number,serial number,electrical rating,frequency,temperature rating etc.
