Serpentine heating elements, also called porcupine elements, are process air heaters with wire elements wrapped in a protruding fashion around a non-electrically conducting core. Unlike coils that would otherwise follow a uniform loop pattern down the length of a tube, serpentine elements introduce each loop or coil to an airflow apart from it’s neighboring loops. This is more easily explained with pictures.

Also unlike open coils that need to be suspended, serpentine elements are supported by an insulating core. The elements are somewhat stiff so they can hold their shape around the insulating core support.

Heater element life is dependent on proper control and element wire temperature. The estimated life-cycle is based on the heater element operating at or below temperatures specified. Most element failures are due to low air flow or damage associated to power control and voltage ramp up rates. If an element has failed prematurely, it should be inspected to determine the cause of the failure. Determining the cause will prevent the same problem from reoccurring.
