2 Zone Fermentation Chamber Build
 
5 Attachment(s)

After getting tired of changing out frozen bottles in my old chamber I decided it was time to upgrade. Besides not using frozen bottles I also wanted the new chamber to have two different temperature zones and have a much higher capacity than my old chamber.

I did quite a bit of research on different designs and eventually incorporated ideas from several other brewers build into one design. Before starting the build I designed the plans in google sketchup. The frame is made out of 2x4 and insulated with 2" Iso foam, sprayfoamed around the edges and then filled the remaining 1.5" with batt insulation.

The top chamber is for fermenting ale and the bottom is for lagers, cold crashing, and aging. I'm using the ebay temp controllers which provide the ability to control heating and cooling. I'm using a 5000btu a/c unit to chill the bottom unit and pc fans to circulate cool air from the bottom to the top. I haven't decided what I will use to heat the chamber but I wired the controller to an outlet in each section so I can plug something in later like a small space heater.

I took care to keep the inside of the chamber well sealed to prevent any mold issues down the road. The inside is painted with an exterior grade mildew resistant paint, I put linoleum on floors and used silicon caulking around all the corners. In addition I'm using a eva-dry unit to absorb any extra moisture.

I brewed the inaugural batch yesterday and it's holding steady at 68. I have the bottom set to about 50 right now and all together have around 30 gallons in the chamber with plenty of room left. The last picture shows the ferm chamber in its new home !

This was a fun build and turned out great. There are a few things I would change if building it again but overall I am very happy with how it turned out. I got a lot of ideas and inspiration from reading other build threads so hopefully I can pass on some knowledge I've learned during this build.

Here's a few closer pics of the inside and one of the inaugural batch fermenting away! I've got my stir plate in there as well, although nothing is on it atm. I can easily fit 4 carboys in the top section alone.

Sure thing, you should be able to download it here.

I didn't put all of the details in the model, such as doors, top, electrical etc. I mainly just wanted to get a better plan on how to frame it. I framed each section independently like the image below shows.

Some of the dimensions I used were based on where I was going to be keeping it. For example I used 4x6 on the bottom and gave it that lip so it would fit closer to the wall in garage. I used the chosen depth to make sure I could still fit 2 cars in the garage.

I also didn't originally plan on putting casters on it. Once I started putting it together I realized that even empty it was going to be tough to move it without them. With the casters added it barely cleared my garage door. If I were to do it over I would probably use 2x4's for the base and maybe even shorten each section by a few inches.

I took a lot of time to ensure the chamber would last a long time. I've read about a lot of people who build something like this and end up throwing it out after a few years due to mold or other problems. The frame on this is definitely sound, my biggest concern was moisture. Between how well I sealed everything up and the moisture absorber I don't think I will have any problems. I also made sure the A/C unit could easily be removed and replaced if needed. This thing should be chilling for many years to come !

I filled all the seams with this stuff before painting. Ended up using like 4 tubes of the stuff for exterior and interior but it turned out great.
