Fermentation chamber cooling options.

[MountainBrothers]

I have seen a lot of fermentation vessels using different kinds of fridges, or freezers, but I haven't been able to find a good, easy, effective, efficient chamber, that doesn't use a fridge. I found a thread that used water cooled fans, but they had the water running through a freezer. Has anyone done this, or can someone point me in the right direction?

My idea:
I plan on buying a new fridge for the kitchen (I had some over carbonated beer in my current one, and a bottle exploded, taking out a couple shelves), so I will probably rig that up for smaller, experimental batches. I would also like to build something that can house 2, 10-15 gallon conical fermenters, for my regulars. I was thinking of just resorting to building a chamber using a mini fridge, but if I could have 2 separate chambers, that would be much better. The benefits of having 2 chambers, would be the ability to cold crash each one at different times, and to be able to work in one, without sacrificing efficiency in the other (if I resorted to the single chamber, I could over look the cold crashing). The problem with having 2 chambers is, I would have to power 2 mini fridges. If I can find a way to efficiently chill each chamber separately, without the use of a fridge, and without having to run something like A/C all the time, that would be ideal.

Any suggestions?

Check out what I did. I found inspiration from the glycol chillers but didn't want to build a gylcol chiller. It works great for a fermenting/serving system for me.

that's awesome. So basically, you just used the freezer to cool the ale chamber, and cold water through a radiator, for the lager chamber?

I just got an idea.. what if I used the freezer side of my existing fridge for the small batches, and had some cold water, and a pump, in the fridge, pumping water through a radiator in my bigger chambers? That would make 1 fridge, 2 radiators, and 2 pumps total. Do you think that would work well enough?
