Industrial Heaters & Heating > Industrial Circulation Heaters

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 National Pipe Thread (NPT) screw plug or ANSI flange heater assemblies combined 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 circulation heater assembly needs. Watlow circulation heaters can be made from a wide range of heating element sheath materials, wattages, vessel sizes and materials, pressure ratings, terminal enclosures and controls.

Cast - X Aluminum Cast Circulation Heaters
CAS’s family of heaters are ideal solutions for demanding applications. These heaters consist of a helical coiled tube and tubular element cast into an aluminum body. The aluminum body serves as the heat transfer media between the tubular element and the coiled fluid or gas transfer tube. The unique construction of the heater allows it to be used where thermally sensitive materials such as paints and resins or flammable materials such as fuels and solvents are being heated.

The aluminum mass acts as a “thermal flywheel” and ensures accurate temperature control of the fluid. Many of our circulation heaters are available with optional explosion-proof enclosures for use in flammable environments. The CAST-X line of circulation heaters are well suited to applications where fluid cleanliness is critical because the material being heated never comes in contact with the heating elements. This is a performance requirement in thefood service equipment, semiconductor and analytical industries. These heaters also come with a heavy wall seamless stainless steel passageway that assures performance in high-pressure applications where viscous or mildly corrosive materials need to be heated.
