Industrial immersion heaters are a fast and efficient way of heating up various liquid solutions in processing equipment, large tanks and containers in many industries. Heating up liquids using direct heat transfer allows for the liquid medium to quickly reach the desired temperature using electric heaters such as flanged heaters, screw plug heaters, over the side heaters or circulation heaters. 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 heaters are an excellent solution to rapid heating in almost any industrial environment.


Flanged heaters have the ability to hold multiple hairpin elements that can be mounted onto the side of a metal tank. Its versatility allows it to offer up to 750 KW of power on a single unit. Among its various uses include utility companies, defense contractors, petrochemical researchers and boiler manufacturers.


Circulation heaters (or In Line Heaters) use immersion heaters such as flanged heaters or screw plug heaters within a vessel chamber to heat up liquids from an inlet and expels the heated liquid through an outlet using the force of a pump to allow easy circulation. The circuit of running liquid is then reheated to reach a target temperature. It is often referred to as the most efficient use of electric heating as heat is initially applied to liquid at ambient temperature but then recirculated at an elevated temperature that does not require as much energy to reach your target temperature. The use of insulation around piping and the tank itself allows the heat to be contained. The circulation vessel is often reinforced with high quality insulation that helps prevent heat loss. Coupled with the use of a high quality alloy that prevents heat loss (high grade stainless steel) the unit is a complete system that allows users to use thermocouples, RTD temperature sensors or standard mechanical thermostats to maintain liquids at optimum temperatures. Safety sensors are also available such as high temperature sensors to help prevent excessive heat or over temperatures. This protects both the liquid you are heating as well as protection to your flanged heater.


The use of electric immersion heaters has been more popular in the past several decades as rising costs of fuels 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 heating has been known to be the cleanest form of heating leaving no residual discharge and provides immediate heat transfer to any medium. Over the side heaters are used to heat up larger containers of liquid that have openings.

Immersion heaters are often available with several different ranges of temperatures that can be fine tuned for extreme accuracy. As such, very tight and efficient control can be maintained which has a positive effect on the performance of the industrial plant. Along with this, several mounting options can be also be availed which further facilitate processes. Examples include screw plug connections, over the side designs and flanges. There are several options for piping as well such as flanged, welded or threaded.
