We made these kilns from 1995 until 2013. It was a manual kiln with Infinitely Variable Switches for zone control and a Kiln Sitter/Timer. We still make the automatic version and most specifications, sizes and features are the same as on the Jupiter Automatic kilns. 

Also see the older versions of these kilns made by L&L Manufacturing Co. Inc.
