| Detail |
Circulation heaters provide a ready-made 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 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 meets virtually all your circulation heater assembly needs with made-to-order units. These units can be made from a wide range of heating element sheath materials, wattages, vessel sizes and materials, pressure ratings, terminal enclosures and controls. |

Features & Benefits
|
Catalog screw plug and flange part numbers provides a wide selection of WATROD and FIREBAR elements to meet specific application requirements |
| |
ANSI B16.5 Class 150 on 4 or 6 inch FIREBAR element flanges and 3 to 14 inch WATROD element flanges meets recognized agency standards |
| |
Compacted MgO insulation filled elements maximizes dielectric strength, heat transfer and life |
| |
Heavy-guage steel jacket (shroud) protects thermal insulation and heating vessel and comes with protective primer coating |
| |
1 inch (25 mm) thermal insulation rated to 750°F (400°C) reduces heat loss from the vessel |
