What size chest freezer to use for fermenting 3 carboys

I wanted to share measurements for a chest freezer I'm using as a fermentation chamber. I needed a freezer that could fit 3 carboys. Surprisingly I couldn't find any clear suggestions online. Most posts were focused on keezers and fitting kegs into freezers, not carboys. But with a bit of guesswork I settled on a 12.9 cu ft chest freezer from Frigidaire. See dimensions in image below:



I purchased this from Lowes and they delivered it the next day.

I plan to use the shelf space for blow off vessels, yeast starters and misc bottle fermenting.

Disclaimer: I took these measurements with a cheap measuring tape and my bare hands, so consider them approximate.

My 7 cubic foot chest freezers fit two 6 gallon carboys on the bottom and one 3 gallon carboy on the shelf. So you should be ok.

I use the same and it works great.

Are you guys using some kind of low profile airlock with the carboy on the shelf? It seems like height would be a problem. Or did u install a collar?

I have used a stopper and tubing to remote locate the airlock.
