Jupiter Powered Bottoms

Technical Details

• Optional bottoms with elements are available for all 23" and 28" diameter Jupiter kilns (in fact all kilns except the J18 and J18X).

• Powered bottoms for the 23" diameter kilns (JD23V-3, JD230V-3, JD236V-3, & JD245V-3) have one element which gives the bottom 1/2 the power of a section ring. (Note that the bottom is a different resistance because the side elements are series and the bottom element is parallel.)

• The 28" diameter kilns (JD2918-3, JD2927-3, JD2936-3, JD2945-3, and JD automatic versions) have two elements on the bottom which gives the bottom 2/3 the power of a section ring.

• The elements have the same resistance as the side elements - which simplifies replacement.

• The bottom elements work off of a separate power circuit. The power circuit is controlled by the bottom zone of the DynaTrol (or Genesis). You also have the ability on the DynaTrol (or Genesis) to control the amount of time that the bottom elements come on relative to the bottom zone (i.e., 10% to 100% of the time that the bottom zone asks for heat).

• You can increase the temperature rating of a JD23V-3 or a JD2918-3 to Cone 10 with a powered bottom.

• The bottom is not reversible on powered bottoms.
