My Dual Fermentation Chamber

[Stinkfist]

So I decided I needed more fermenter space and I also wanted to be able to ferment at 2 different temperatures...So here is what I came up with

My design, drew it up in autocad...which turned out to be amazing everything just fit up perfectly!




And the build






Turns out I really needed two fans, one was not enough to cool the outer chamber...the inner chamber would reach its temp but the outer would not, So I added another fan below the other one but this one blew into the inner chamber, creating a nice circulation. you can also see the draft flaps I installed on the fans to keep them separated when the fans are off



and the final product with the nw controller for the fans


So far this thing is working great but the real test will be after tomorrow as I am planning a double all grain brew day to fill this thing

Can you post the stp file? That looks nice yet simple.

Nice job Brotha!

Is there and air return back through the door to the fridge?
You might not need it but just a thought.

Looks good. What's the temp variation you can hold between the two chambers and how is that controlled? Can you lager in one and have ale in the other, or are you talking only a variation of a couple of degrees?

Jack not sure it will help much as it was designed to work with my specific mini fridge.

Yeah there are two fans one blows from inner chamber and the other blows into the inner chamber, I tried with just one but the inner chamber would reach the temp before the outer so I had to add another luckily I planned for that and ordered two

So far I have found it will work better if I lager in the inner chamber and do ales in the outer chamber. If the inner chamber is too warm it will take too long to register the temp change on the inner Carboy to cool the outer. But if I am at lager temps say 50 it works very well.

Great looking build. I have been combing the net for an idea for my chamber build and really like what you have done. I'm an apartment brewer and space is limited, so I want to build a chamber that can cover both lager and ale temps.

First I need to find the proper refrigerator. Can you share the make and model of the one you are using?
