Control fermentation temp.

[Rick Crane]

Hi!
I was in the introductions forum and was just informed that I have been promoted to the beginners Forum.

I want to find, (buy new) a fridge or chest cooler to hold my 5 gallon carboy with airlock so I can control fermentation temperatures. I will buy an aftermarket temp controller. Right now I want to ferment ales. I just need the carboy to fit inside, so I can close the lid, or door without modification.
thanks.
Rick

Also look on Craigslist and other local market places. Friends or family may have a spare fridge or freezer they don't want or need anymore. Win-win for both.

Depending on your available space, getting a somewhat larger unit may help future proofing your purchase and efforts, allowing you to use certain fermenters that just need more space or accessories (e.g., Speidels, Fermzilla, conicals). Or maybe ferment 2 beers at the same time.

Thanks. I know that guy was messing around, so I figured I would keep it going,

What I want is for my condo, 850 sq ft. I looked at home depot online and see one that is 3.6 cubic feet the dimensions were close, but I think I need like 12x12xnot sure how tall inches at the very minimum, so a 5 gallon carboy will fit. So the 3.6 may not work. The 5 cubic ft one may work well, and it is less than $300.00. The bottom of the chest freezers have a step in them. Does anyone else have a small chest freezer they use?

Lots of us use, or have used, chest freezers. (But I have no experience with really small ones.)

You might find this thread helpful...

But the best bet (especially for models not discussed in the other thread), IMO, is to measure your equipment, then go to the big box store (or wherever) and measure internal dimensions yourself.

 

[Rick Crane]

Thanks, found the thread very useful indeed. A lot of time and effort went into that thread and the spec sheets. My car is being fixed, i will get to Home Depot and Lowes soon to look at units up close.

Here's a FANTASTIC build for a mini-fridge single-carboy fermentation chamber. I followed the guidance in this thread, and I couldn't be more pleased!

I'm in the same situation and I've been looking at different products out there so I figured I would share what I found. So far, this one looks like it's big enough for most 5 gallon carboys (even with the freezer), has good reviews, removable shelves, and one of the cheapest for it's size.

I know the box stores have had runs on chest freezers for all the doomsday preppers. That being said, HBT is a great resource for others who have built that list the exact make/model for your referencing. You can always bring a couple of empty corny kegs (or buckets, etc.) to the store...get weird looks...and then physically see if it'll fit. As you've probably seen in other posts already, a wood collar can be affixed to the top to provide more headroom (and to make a suitable material for running faucets, etc.).

Thank You, After you get it, let us know what it's like.

No problem. I haven't decided which one I'll be getting yet, just sharing the ones I found that look most promising. This one looks like it would definitely be big enough, cheap, and supposedly all shelves and bottom drawer can be removed. Very good reviews as well. Magic Chef 4.4 cu. ft.

Make sure to have some loose wires coming out of your kegs and running to a clock if you REALLY want to get some looks at the store (and probably a free tour of your local FBI office).

 

[AJinJacksonville]

Whatever you do, just don't trip and fall and roll it into the store...even more of a sure way for a free ride and tour...haha.

 

[NateDawg]

OR you could just get a tape measure and measure the dimensions of the carboy, then measure the interior of the fridge without turning any heads or needing to carry around a big container haha

I mean, sure, that's one way to do it.

 

[DVCNick]

Mine is about 7.5 cubic ft I think and will hold two carboys without modification.

I don't regret it at all and if there is a chance you might ever want to do ten gallon batches it is good for future proofing. It was about a year old, $125 on craigslist.

Here is my Frigidaire chest freezer inside dimensions 16”front to back 22” wide 19” deep to top of step and 28” deep without step . I added a 2x 6 collar that I leave loose on top of the freezer so I can remove the lid to get the empty half keg out easier. I use an inkbird controller. After fermentation, I pull out my blow off tube to prevent the keg from siphoning my airlock water back into the keg, then cold crash.

 

[Alphadawg]

I just bought this 5.0 cf freezer and think its great. Its plenty deep for a 6.5 carboy with airlock and I can even put smaller carboys on the step. Less than $200

I just received this yesterday and have it set up. At the moment I only have 1 and 3 gallon carboys... but it looks like a 5 gallon would fit. I could provide interior measurements if anyone interested.

awesome, thanks for the info. I'm leaning towards going with a freezer at this point, so don't bother with measuring the dimensions (unless someone else needs them)

FWIW, this is what I'm thinking about getting at this point because it's very big for the price... Hisense 7.0 CF Chest Freezer - Walmart.com
The only problems are is out of stock (probably due to doomsday preppers as someone else had mentioned). Also, the reviews aren't great because it often comes dented when ordered online, but sounds like very few people have had functional problems. I was thinking I might pick one up in person when it's back in stock but I don't really mind if it comes dented.

Here are a few other decent products I found for anyone that might be interested in getting a freezer...

I will go to a freezer at one point myself... and this fridge will become a beer cooler. Have you checked the upright freezers? Easier to get things in/out. Can see better etc. Look like they may accommodate taller conicals possibly. Would be interested in the interior dimensions on this. Of course, there are larger ones but they get pretty expensive. This looks like pretty good price with good reviews:

That one is really nice, would be better than a chest freezer especially since my carboys have spigots on them. The only thing is I'm trying to keep it in the $200 price range and it looks like most of the upright freezers are significantly pricier than the chest freezers.

I think I've made my final decision mainly because I don't feel like researching this anymore haha.

Going with this one because it's wide enough to fit 2 larger carboys (5 - 6.5 gal), excellent (and many) reviews, price is $220, which is a little higher than some of the others I've been looking at, but I think the longer width and the fact that it appears to be a better quality product makes it worth the extra money imo.

 

[LittleRiver]

... this is what I'm thinking about getting at this point because it's very big for the price... Hisense 7.0 CF Chest Freezer - Walmart.com

The larger size will give you plenty of space for multiple fermenters, with space left over. Get a couple of re-usable dehumidifiers, and keep one in the freezer all the time.

My keezer is based on that freezer. It's only about a year and half old, but no problems so far. I got the freezer brand new in a slightly water damaged box at a building supply salvage place for $90.

Yep the upright are more expensive for sure. That one there is pretty nice and good price! Beware... if you plan on best buy shipping to your house. They are notorious for shipping damaged appliances. Heck a reseller next to me ... has entire store stocked with dented best buy fridges. and online all kinds of folks complaining about damaged fridges and they have to bring the appliance back to store themselves.

Thanks for the advice, but I'm wondering what is the purpose of the dehumidifier? I'm thinking a dehumidifier will not affect the humidity inside the carboy because the airlock will prevent external air from entering the carboy?

Your fermenters will be belching moisture laden gas. You have to control the moisture somehow, otherwise you will get mold growth inside your chamber.

Makes sense. Didn't think of that

 

[Moose_MI]

I will humbly submit for consideration that you dont need a freezer to control fermentation temperature to do most ales. A plastic tub filled 1/2 with water and a couple ice packs during the first 2-3 days is all that is required.
So, if you decide to go with the freezer for ferm chamber and after a few beers you dont really notice a difference...come back...we’ll help you turn into something useful like a keezer...you’re gonna love kegging

Since Covid 19, Freezers have been hard to find at a decent price. The sellers admit the prices have gone up due to demand. I live in an apartment with limited space and recently purchased this mini fridge.
Frigidaire 4.4-cu ft Freestanding Mini Fridge (Silver Mist)
Item #821163Model #FFPA4422UM Goes for about $150 depending on the sale.
It has no freezer at the top to take up space, so internal dimensions are better than most. I connected to an Ink-bird. It will hold a carboy or a corny keg. Due to height restrictions, I skip the air lock on top and run a hose to pan of water in the fridge for a bubbler. Otherwise, I have used just to hold a keg at temp to continue the process.

How do you maintain steady temp with this method? I’m assuming you would have to use a thermowell for this?
