Watlow Circulation Heaters provide a readymade means to install electric heating with a minimal amount of time and labor. This is accomplished by combining heating elements, vessel, insulation, terminal enclosure, mounting brackets and inlet and outlet connections into a complete assembly. Made from NPT screw plug or ANSI flange heater assemblies mated with a pressure vessel (tank), circulation heaters are designed to heat forced-circulation air, gases or liquids. Ideal for either in-line or side-arm operations, these assemblies direct fluids past FIREBAR® or WATROD heating elements, to deliver fast response and even heat distribution. Watlow can meet virtually all your circulation heater assembly needs with made-to-order units. Made-to-order units can be made from a wide range of heating element
sheath materials, wattages, vessel sizes and materials, pressure ratings, terminal enclosures and
controls.
