Abstract
In an illustrative embodiment, a flow-through fluid heating unit includes an annular member, and a heating element deposited on an inner surface of the annular member, the heating element including three sub-heating elements, each sub-heating element being connected to a separate conduit for receiving a separate phase of a three phase electrical power source. The heating unit may include a baffle core including at least one channel providing a fluid flow path, the baffle core being disposed within the annular member and proximate to the heating element. First and second end fittings may be disposed at each end of the annular member, each end fitting including a fluid port for allowing the fluid to flow through the annular member. One of the end fittings may be releasably connected to the annular member to provide access for removal of the baffle core.
