Flange and Screw Plug Circulation Heaters

----Flange and Screw Plug Circulation Heaters.jpgCirculation heaters (in-line heaters) are an assembly with an immersion heater installed into a mating tank or vessel. The liquid or gas flow through the vessel picking up heat from the immersion heater. The immersion heater consists of hairpin bent tubular heater elements brazed or welded into standard size screw plugs or flanges. The circulation vessel is typically constructed of pipe sections, a mating heater fitting, inlet/outlet nozzles, drain, and insulation shroud. A wide variety of standard circulation heater designs are available, as well as, custom engineered solutions.
