- They consist of an electrically resistant heating element enclosed in a protective sheath. Upon activation, the heating element warms its surrounding jacket, which, in turn, heats the sheath, ultimately raising the temperature of the liquid. The effectiveness of this process depends on the conductivity of both the jacket and the sheath.

Flanged heaters act as a sourceof direct heat to a liquid medium. They typically use hairpin elements or tubular bugle elements that extend from the flange’s face. These heaters usually contain thermowells that allow for the use of temperature reading devices such as thermocouples and thermostats to provide better temperature control. These devices...
Circulation heaters have a wide rangeof applications, making them a highly-prized type of industrial heater. The target fluid enters through an inlet that’s closest to the heater. The heater then applies heat to the liquid as it flows within a vessel. The fluid then exits the outlet and circulates through a piping circuit. How these heaters functio...
Over-the-side heatersare a type of immersion heater designed for installation outside of a tank or vessel. Usually, they are installed in the upper portion of the vessel, with brackets fastening the heater onto the tank wall. Over-the-side heaters often use copper, steel, cast alloy or titanium in their heating elements. Due to the mobility of thes...
Screw plug heatersare submersible heating elements that go directly into the tank or vessel. They deliver a direct transfer of heat, which allows liquids to heat up rapidly. Screw plug heaters contain hairpin tubular elements that are either brazed or welded into a pipe thread fitting. Screw plug heaters are ideal for smaller containers and vessels...
Depending on your application, the kind of immersion heat you need will likely be apparent. Of course, there are cases where you will need to assess the demands of particular processes and which immersion heater will best suit your needs. That may mean carrying out specific calculations and determining cost-benefit analyses. However, our Wattco rep...
Jun 6, 2024 · Immersions heaters, according to their names, are directly immersed in the liquid substance being heated. This direct contact between the heating element and the item being heater means that only a minimal amount of energy is lost during the heating process.
Sep 23, 2019 · Immersion Heater Definition. What defines an immersion heater? After all, common electric-coil furnace elements are immersed in air. This discussion concerns itself with the adverse effects of improper heater design and fluid pairing. In particular, this relates to a phase change or reaction in the fluid. What does that look like in practice?
The direct immersion method is energy efficient and well suited for many applications. An immersion heater is a device which is installed in a tank or container to heat a liquid. The installation can be over-the-side, flanged or threaded.
Oct 7, 2023 · An immersion heater uses an electric heating element to heat water. The element, which resembles a metal loop, is placed inside a hot water cylinder in order to heat the surrounding body of water. The cost of an immersion heater element will depend on the metal it is made from.
