An electric process circulation heater is used as a conduit to facilitate the flow of process fluid directly over heating elements. Circulation heaters heat a variety of fluids from high-temperature gas to hard to heat liquids.
The heating elements, vessel, terminal connections, and mounting structures are packaged for quick installation. Heaters may be installed horizontal, vertical or even sloped for vaporizing liquids.

Mounting options include saddles, skirts, mounting blocks, mounting lugs, legs, base plate, or a combination of two.
Multiple nozzles may be included as part of the heater. The inlet and outlet nozzles are placed so that the fluid is always flowing over the heated sections of the elements. Optional nozzles include vents, PSV connections, and drains. A temperature sensor may also be placed on the inlet nozzle, outlet nozzle, or both for process control. Temperature sensors include a thermowell that may be NPT, socket welded. This is the perfect solution for the job where “plug and play” is desired.
Let Sigma Thermal mount and prewire the heater and panel on a common skid base. All that is left is the power supply and connection pipe. The easiest way to have your heater up and running in no time. We will even come and help you start it up.
Circulation heaters are available in a variety of materials, including carbon steel, low temp carbon steel, 300 series stainless steel and nickel-based materials. Gaskets and bolting are selected based on process and design requirements.
