First I would like to point out that this is NOT my design.. i found it in my research of different brewing systems..
But this is a great DIY fermentation chiller that does not require you to purchase a chest freezer or fridge..http://home.roadrunner.com/~brewbeer...er/chiller.PDF
Yep, the son of fermentation chiller has been around for quite a long time, and there are many variations on it. There are several threads about it on this site.
