Our 10' x 4' mobile vacuum kiln for drying wood slabs and chemical free pest/beetle/termite extermination. Built with salvaged oil tank and off the shelf parts. More details and update: We recently purchased a Electric Radiant Floor Heat Heating System on Amazon and sandwiched it between 1" plywood and the steel plate. It heats the entire 'floor' evenly to approx 80 degrees. Water boils at room temperature in a vacuum, so the temp is sufficient. I also lay an additional flexible heat pad on top of the slabs to increase heat evenly. I start with a 9 cfm pump, then move to a small 1.5 pump to maintain pressure. No drain, no condenser. We can only run small jobs.
