Econo Kilns (J models)

These were the predecessor kilns to the manual Jupiter kilns. Although a few specials were made with automatic controls, almost all used an externally mounted Dawson Kiln Sitter/Timer. They were made from about 1970 to 1995. All had 2-1/2" of firebrick. They also featured infinitely variable input switches on each zone, a separate control panel that mounted off the kiln on the side with cords that ran from the kiln sections to the control panel (similar to what is on the Jupiter kilns today), UL listing, element holders, and solid peephole plugs. Many of these were made and many are in operation today. Sizes ranged from the J18 (17-1/2" diameter by 18" high) to the J2945 (29" diameter by 45" high).
