Yeah, took some time to think about what was made. I had my eyes set on the project from byo. Byo had it so the coils were wrapped around the fermenter and the link you gave had a glycol cold box. The guy who made the glycol chiller cold box (http://forum.northernbrewer.com/viewtop ... ol+chiller
) looks like a home made fridge, if I'm not mistaken.
Between the two styles, I couldn't go with the glycol chiller cold box, because my wife would veto that purchase because we already have one fridge in the garage. Can't have another.
So I'll probably go with the byo glycol chilled fermenter.
