Chest Freezer Kegerator

For this Kegerator, I used a Black Frigidaire 7.2 cu. ft. Chest Freezer that I picked up on sale at HHGregg for $240.  I wanted to use a chest freezer because it seemed like the simplest, most energy efficient and most self-contained kegerator that I could build.

The first thing that I did was detach the door from the freezer.  Each hinge is attached to the freezer with 4 screws and to the door with two screws.  Since I was planning on building a collar onto the door, all I needed to do was remove the screws attached to the door and leave the hinges attached to the freezer.

The door consisted of 3 basic parts:

1.  The rubber gasket that runs along the bottom of the door to provide a seal to the rest of the freezer when it's closed.

2.  The white plastic lining which forms the inside part of the door.

3.  The outside part of the door which contains insulation.

All of these parts were held together by 4 screws and several small plastic push-in clips that are easy to pull out with a claw hammer and could easily be used to put the door back together in its original state.

(I apologize for not having more detailed pictures of this but I didn't start taking pictures until the door was already off and taken apart.)

Thanks! Good points all

I just bought a similar freezer and wonder why I need to drill into it for the (new) temp probe. Off the shelf, the freezer already has a temp probe connected to the existing thermostat (I think the pic here has that too - the red nub connected to the grey line coming out of the "existing thermostat" in the 2nd image). It's pretty easy to pull that temp probe out. Is there any reason I can't just insert the temp probe from the new thermostat into the same hole? That would mean no drilling and no potential to hit a cooling line (the ambient humidity here is super low - my freezer doesn't have condensation lines showing where the coolant lines are like yours), and no temp probe dangling inside the freezer compartment.

I don't see why doing what you've suggested wouldn't work. What I don't know is if there's room, in that space, for the temperature controller thermometer bulb that is being added. But if it fits, I would think it would just be a question of calibrating it to take into account being inside the wall of the freezer instead of inside the freezer itself.

The way I built it, the temperature bulb is floating freely and surrounded by air, so that it would give the most accurate measurement of the air in the freezer, and because by doing it the way I did it I can always use it as a functioning freezer again, if need be. Also, for the freezer I used, I'm pretty sure there were no cooling coils in the horizontal surfaces of the freezer, all of them being in the walls instead, so it's relatively safe to drill that hole, especially given how close the wall it is.

Good job Scott! I like that your design keeps the hoses and faucets out of the way when loading and unloading the chest with kegs. Also, I didn't know about the humidity issue but you came up with a good solution to that. Thanks for sharing your knowledge and expertise.

If you make the collar taller; (mine is 15 inches in height), You will be able to put more kegs on the compressor shelf, and also out a drip dray under the taps. Great instructable, and I think my initial idea was from you!

That's true. However my goal with the collar was really only to give myself enough space to be able to house the faucets and have enough extra height for the CO2 tank on the shelf. I was a little concerned about how much the door hinges could support if I added too much weight to the top via the added collar. (The biggest issue I've seen is the compression of the rubber seal by the weight of the door and collar, which would be worse the bigger the collar the collar is.)

I've toyed with getting a magnetic drip tray, but it's not worth the price for me when a square bucket under the taps works just as well and is way easier to clean. :)
Woodworking stores (rockler, woodcraft, etc) sell very large hinges for things like solid wood lids (picture a large chest with a flip lid). Some have some spring to them, so they counterbalance the weight of the door. The trick there is finding somewhere on the base that's solid enough to attach hinges that add 50lbs of force each.
BEAUTIFUL!!!

How many cornies can you fit in there @ once?

This will fit 3 cornelius kegs in the area of the freezer next to the compressor shelf.  (Technically, if you wanted to get a 2.5 or 3 gallon corny keg to set on the shelf next to the Co2 tank, you could have 4, but then that would mean installing a 4th faucet and all of the requisite tubing.)
