Understanding Immersion Heaters Immersion heaters are electric heaters used to apply temperature to water, oil, chemicals and gases to keep these substances neutralized. They’re useful in a number of industries, including chemicals and petrochemicals, and provide a safe and environmentally responsible means of heating large quantities of various substances. There are three basic types of immersion heaters – over the side, flanged and screw plug/threaded. All of these electric heaters have control units that are kept separate from the substance the heating component is immersed in. Over the side heaters are used mostly in vessel tanks. They are installed from the top of the tank and run all the way to its bottom. When activated, the device evenly distributes heat, allowing it to keep the contents of the vessel tank at the right temperature. These electric heaters have sturdy, durable heating elements that resist corrosion and other hazards. Typically, heating elements in over the side immersion heaters are made from steel, copper, cast iron or stainless steel and have a lithium or PFA coating. The shape, size and model of the heater vary, depending on several factors, including the type of heating element used. These immersion heaters are typically used to process viscous content such as oil, plating baths, salts, solvents and more. Over the side heaters are relatively easy to maintain and are very portable. Flanged heaters are immersion heaters installed in a tank so the heating device is immersed within the substances inside, while the control box is connected to a nearby exterior wall. Flanged heaters get their name from their design, which consists of a hairpin bent tubular heater element fused to a flange. Flanged heaters come in a variety of sizes, voltages and sheath material kilowatt ranges, and also have a variety of terminal housings. The variety of designs makes them useful for a variety of heating needs. Flanged heaters can commonly be found providing heating for oil, water, chemicals and gases inside their tanks. They provide direct and evenly divided heat and are very corrosion resistant. Screw plug/threaded immersion heaters are a lot like flanged heaters as they each have hairpin bent tubular heating elements that are fused to the control box. These electric heaters come in a variety of sizes, depending on the tank they’re used to heat. Screw plug/threaded immersion heaters are most commonly used to protect tank contents from freezing. When considering an immersion heater for your industry, think about the heating needs of the materials you use and which heater design will likely work best for them. Also inquire about specific brands of heaters and how well they perform for other users. Wattco provides high quality immersion and other heaters, and offers low prices and a quick turnaround time.
