TUBULAR HEATER Tubular heaters are used mainly in custom heating applications. They can be formed into various geometries and are designed for either radiant heating or contact surface heating. Often, tubular heaters are immersed in substances such as water, oil, or molten materials. Because they generate heat within the liquid or process, tubular heaters are extremely energy efficient. Suppliers categorize tubular heaters as single-ended or double-ended. Single-ended tubular heaters have two terminals at one end. Double-ended tubular heaters have one terminal at each end of the tube. Tubular heaters with round heating elements and flat or triangulated heating elements are also available. Dimensional considerations included heated length and heated width. Tubular heating elements are versatile and perform exceptional heat transfer by conduction, convection or radiation to heat liquids, air, gases and surfaces. In most heater assemblies, tubular element design configurations vary round, triangular, flat press and formed bends are made to customer requirements.
