Watlow circulation heaters combine the popular Watlow WATROD® or FIREBAR® heating elements together with a tank, insulation, terminal enclosure, mounting brackets, inlet, and outlet connections to form a complete assembly. Watlow circulation heaters, therefore, provide a ready-made means to install electric heating with a minimal amount of time and labor.

Watlow circulation heaters are designed to force circulated liquids (air and gases may also be appropriate depending upon the application) over a heating element. Watlow circulation heaters are ideal for either in-line or side-arm operations. By using industry-leading FIREBAR® or WATROD® heating elements, these Watlow circulation heaters deliver fast response and even heat distribution.

Watlow circulation heaters maintain the high performance capabilities for which all Watlow heaters are known. Watlow circulation heaters are rated up to one megawatt, generating watt densities up to 120 W/in2 and sheath temperatures of up to 1600°F (depending upon sheath material). The tanks are insulated with one inch of thermal insulation rated to 750°F to reduce heat loss. A heavy gauge steel jacket protects the entire assembly. A wide range of sheath materials, wattages, vessel sizes and materials, pressure ratings, terminal enclosures and controls are available to the Watlow circulation heaters to meet virtually all your circulation heater assembly needs.
