Abstract
A device for heating a fluent material (e.g., gaseous or liquid media, such as air, water, etc.) comprises one or more electrical induction coils arranged around one or more central conduits for the medium to be heated, inside which coils there are arranged rings or spirals of metals which form one or more electrically-closed circuits, possibly after addition of short-circuit parts, which circuits, and possible metallic partition walls at these, are arranged to be inductively heated when the induction coils are electrically energized, heat generated in the heating elements passing to the fluent material flowing through the passageways.
