Electric Circulation Heaters

Electric Circulation Heaters

Electric circulation heaters heat a flowing liquid or gas as it passes through an insulated pressure body containing electric heating elements. They are useful where the process requires continuous heating, a controlled outlet temperature, and compact integration into pipework. The heater body, element surface loading, flow path, and control arrangement must be matched to the medium's properties and operating pressure. Fluid viscosity, gas density, flow rate, inlet temperature, and allowable pressure drop all affect sizing. Low-flow or no-flow conditions can cause element overheating, so flow switches, pump interlocks, and independent high-limit protection may be necessary. The unit can be supplied as a component or integrated into a circulation skid with pump, valves, instruments, and a power panel.
