Abstract
Heater assemblies comprising a cylindrical body with a surface and a central axis including a plurality of heating elements are described. The plurality of heating elements is axially spaced on the surface of the cylindrical body. Each of the heating elements forms an axially spaced heating zone. Each heating element has a spiral shape with an inner end and an outer end defining a length of the heating element. Each coil of the spiral shape is spaced from an adjacent coil by a distance sufficient to prevent arcing between adjacent coils.
