Immersion Heaters are a fast and efficient way of heating up various liquid solutions in processing equipment, as well as in large tanks through the use of tank heaters. Heating up liquids using direct heat transfer allows for the liquid medium to quickly reach the desired temperature using electric heating elements such as flanged heaters, screw plug heater, over the side heaters or immersion water heaters.
Over-the-side immersion heaters are designed for vessels where through the side immersion heaters cannot be conveniently installed. These heaters are installed through the top of the vessel with the heated portion of the unit along the side or at the bottom of the tank. Natural circulation of the fluid inside the vessel allows for even distribution. Terminal houses or lead wires are provided for power connection.
This application is commonly used in chemical processes, large petrochemical containers as well as large water containers that require fast heat up time. With minimal maintenance requirements, immersion heater are an excellent solution to rapid heating in almost any industrial environment. The use of electric immersion heater has been more popular in the past several decades as rising costs of fuels (and the necessary infrastructure that comes with it) force individuals to select a more cost-efficient way of heating their applications. Ecologically conscientious groups have long advocated for cleaner energies to help save the environment. Electric heaters have been known to use the cleanest form of energy, leaving no residual discharge and provide immediate heat transfer to any medium.
The large variation in heating element material and shapes of over-the-side immersion heaters offers a wide selection in the application of these units. Water, oils, solvent, plating baths, salts, and acids are some of the many liquids and viscous materials commonly heated with immersion heaters. Over-the-side types permit portability, easy removal for cleaning of tanks and heaters, and ample working area within the tank when installed.
