Watlow’s immersion heaters are designed primarily for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases. By generating all the heat within the liquid or process, these heaters are virtually 100 percent energy efficient. These versatile heaters can also be formed and shaped into various geometries for radiant heating and contact surface heating applications. UL® and CSA component recognized elements are available.
Over-the-side heaters are ideal for heating water, oils, solvents, salts and acids. Over-the-side heater application versatility is enhanced with optional sheath materials, kilowatt ratings, terminal enclosures and mounting methods.
The L and O shaped “installed-from-the-top” heaters slide easily into tanks, with the heated portion immersed along the side or at the bottom. The drum immersion heaters are designed for direct immersion in a standard 55 gallon steel drum. Watlow® vertical loop immersion heaters are well-suited for open tank applications.
