- Immersion heaters feature an electrically resistant heating element enclosed in a protective sheath. When activated, the heating element warms the surrounding jacket, which in turn heats the sheath and subsequently the liquid. The heater's effectiveness relies on the thermal conductivity of both the jacket and the sheath.

Nov 23, 2020 · Immersion heaters are a popular application in the oil & gas, petrochemical and manufacturing industries. Their operational principle is simple and is based on the direct heating of a fluid body when the immersed heating element is operating while placed inside the fluid body.
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?
Nov 28, 2023 · Immersion heaters are integral components in the heat transfer process, contributing significantly to various applications. They operate through basic principles such as conduction, where direct contact with a liquid facilitates efficient heat transfer; convection, which involves the movement of heated fluid for uniform warming; and radiation ...
Jan 20, 2022 · Electric heat exchangers have electrically resistive wires inside of the tubes (Called electric heating elements) that create heat. Temperatures can range from -260F to as high as 2500F. Electric heating elements are very efficient at transferring heat to the product flowing through the vessel.
