Home Applications Electric Oven Heating Elements
Immersion heaters are one of the most widely used methods for heating liquids (such as water, oil, heat transfer fluid and
corrosive solutions). Designed for use in tanks and pressurized vessels, they are easy to install and maintain to provide
heat for many processes. The direct immersion method is energy efficient and easily monitored and controlled.
