Kecked, I need to ask Farbe how much the vacuum pressure affects the stacked TEC performance, i.e. if .01, .001, .0001 and .00001 Bars. I expect he can give me some idea.
At this point, I think I've highjacked the thread. I better make my own on this project. This thread is meant to see who might want to buy these units as a group to make them less expensive.
