Fermentation Chamber
« on: September 15, 2020, 11:55:22 PM »
I decided it was time for an upgrade to my fermentation chamber. I built the "Son of a Fermentor" about a year ago and, while it worked great, I wanted something that could hold two carboys and not require me to swap out ice jugs in an attempt to control the temperature.
To keep cost down I was able to reuse the foam and fan from the "Son of a Fermentor", I got the ac window unit for free, and used my bucket heater. To control everything I am using the Inkbird ITC-308. The frame is all 2x4 and the exterior is .25" plywood. The interior dimensions of the chamber are 24" x 36" and 30" tall. I used 2" and 1" foam to insulate things, and used spray foam to fill in all the gaps. I put wheels on the bottom when I realized that I wanted to be able to move it around without help from a few friends. Cost for all the parts that I already didn't have was about $175

Insulation installed


Frame for the chamber


Top and one side wall installed


Put first wall on wrong side...swapped and put two more walls on


All walls on and foam installed


Inside look of the ac unit. The openings above that are for a heating chamber I built. (pic below)


Door frame done and foam insulation installed on top


Here you can see where the ac unit is hiding. The frame above that is where I built a heat chamber. Air comes in on the right, gets warmed by the bucket warmer, and blown back in the chamber. I liked this setup because I'm not dealing with a heating element that gets really hot but can still warm things if needed.


Door is on. It's snug, but I'm willing to accept some leakage around the door.

That looks incredible!  Great job!  I wish I had the space for something like that.
