Abstract
A heating apparatus for a fluid flow system having a container body includes a heater element and a strip. The heater element is within the container body and includes an electrical resistance element, a sheath, and an insulating material. The sheath extends along a predefined path through the container body and surrounds the electrical resistance element along the predefined path. The insulating material is disposed about the electrical resistance element between the electrical resistance element and the sheath. The insulating material electrically insulates the electrical resistance element from the sheath. The strip is disposed inside the container body and defines a tortuous geometry that follows the predefined path. The strip defines a plurality of openings at discrete locations along the strip. The heater element extends through the plurality of openings and is configured to contact the strip at the discrete locations.
