Circulation Immersion Heaters
Product Overview
Circulation heaters are packaged units designed to heat a flowing medium using inline or side-are pipng configurations. Complete units consist of built-in heating elements, a heating chamber, thermostat and/or sensors (stock units), insulation, insulation jacket, mounting brackets and inlet and outlet connections.
More Information
Circulation heaters offer high efficiency since all heat is generated within the solution. Fluids are directed past the heating elements giving fast response and even heat distribution.
A wide selection of kilowatt ratings, materials, vessel sizes, terminal enclosures, control features and mounting methods are available for all types of heating requirements. SCR and Contactor Control Panels available for integral or remote mounting. Consult Controls section for details.

Special Features
Kilowatt Ratings
Large kilowatt circulation heaters (500 kW and above) are available as single chambers or with multiple chambers in series. Skid mounting and integral control panels are also available. Vessel Construction Chamber size available in 10, 12, 14, 16, 18" and above for larger kilowatt capacities. Pressure Ratings 150, 300, 400, 600, 900, 1,500 and 2,500 Lb. Class. Materials 304, 316, 321, 347 Stainless Steel, INCONEL® and more. Thermocouples can be provided on element sheath for overtemperature protection and/or mounted in the outlet nozzle for process control. Inlet and Outlet Nozzles Available with flanged or threaded connections, smaller or larger pipe sizes and different orientations. Baffles mounted on element bundle inside chamber to increase fluid or gas velocity.
