Inline Process Heaters

Inline Process Heaters

Inline process heaters are installed directly into a pipe or circulation circuit to raise the temperature of a flowing liquid or gas. The compact arrangement can support continuous heating without requiring a large storage tank, provided that flow, pressure, heat-transfer area, and control response are properly matched. The heater body, element sheath, seals, and connections must be compatible with the process medium and operating pressure. Sizing requires the medium's properties, mass flow, inlet and target temperatures, and expected heat losses. Low-flow conditions can cause excessive local temperatures, so flow proving and suitable high-limit protection may be needed. For viscous fluids or gases, pressure drop and heat-transfer performance must be checked carefully. Inline heaters can be designed for water, oils, compatible process liquids, and gases, with the final construction determined by the application.
