Hey guys, just thought I would put up some pics of my fermentation chamber I just built, just to have another one out there in case it helps anyone with ideas or another way to skin a cat.
I used a scavenged dorm fridge to cool the thing. In the summer it is holding 65 like a champ for ales. I tried it out, it can get down to 45 and hold it, but I don't want to burn out the condenser, so it will be ales in the summer while my basement hovers around 80, and lagers in the fall/winter when it hovers around 65.
The frame is made out of 1x3's, with two sheets of one inch foamboard on all sides. It is skinned with 1/4" plywood. In the bottom section I also added another sheet of 1/4" foamboard because I had it lying around, so figured why not reinsulate the bottom. Here is the cross section of the bottom as I built it:
I used plexiglass I scavenged from work to line the entire inside, so the dimensions of the plexi kind of dictated the build. Here is the bottom built with the plexi screwed in:
Here's a wall, without the installation added yet:
Once I got all three walls up, it was time for insulation:
Filled any gaps with spray foam to insure insulation. I put a plywood skin around the whole thing:
And wired up a couple fans. The fans turn on when the Johnson turns on the fridge.
It will hold three buckets and a couple kegs. I can't wait to use it for some lagering.
