Default My Portable Kegerator Build

When I first started brewing, I became very popular with my wife's family - every holiday I'd bring a couple of cases of homebrew. But then I started kegging, and now I only bring homebrew when it's cold enough outside to keep the keg cold (which is not very often in my part of Texas).

I want something to keep a keg in that keeps it cold but is also small enough to be portable, but I don't want to mess with ice, so I came up with an idea for a kegerator that is just large enough to hold a 5 gallon ball lock keg.

I started by scanning ebay and trolling consignment stores until I found a cheap mini-fridge. I found this one at Goodwill for $35 - it was ugly and a little smelly, but it got very cold when I plugged it in.



There was a little mold on the door (something SWMBO pointed out when she noticed it in the back of the car - this was right after she reminded me that I already have two freezers in the garage devoted to homebrew (a kegerator and a fermentation chamber)). But you could hardly smell it after it was turned on for a while.

My initial plan was to build an insulated box attached to the mini fridge to make enough room for a keg. However, this wouldn't have been quite as compact as I'd like it to be, and it also wouldn't look that nice. Then I remembered that we had this...



It's a stainless steel trash can. At one point it had a foot pedal to open it, but that fell off shortly after my boys discovered that a trashcan lid popping open makes a good catapult and that the harder you stomp the faster the payload takes off.

We had put off replacing it, because we didn't think the boys needed a new catapult that badly. But when my wife saw me measuring it and lowering an empty ball lock into it she commented, "So you think it's time we get a new trashcan, huh?"

With a plan formed, I only needed time to get started. An opportunity presented itself when my wife went off for a girls' weekend with her mom and sister. As she was leaving I said, "I'm probably going to destroy that mini fridge this weekend." (Her response: "That's ok.")

I began by removing the door - no more mold:



Then the fun began; I started prying off the sides.



Here's one side off:



And here's the top off:

I apparently didn't take any more pictures of the mini fridge tear-down, but after pulling off the outer shell I separated the coil from the fridge and cut a hole in the back to pull the cooling plate through.

Here is the guts of the mini fridge:



I very briefly plugged it in, and the plate immediately started getting cold - I hadn't broken it yet!

The stainless steel trashcan wasn't quite tall enough to hold a keg and allow room for the connectors, so I used a black plastic trashcan to extend the bottom. This picture shows the bottom - in it I've started running the parts of the fridge where they will need to go. (The board the black plastic bottom is on is attached to the frame the compressor is on; screws hold the black plastic bottom on it, and the board will be the base of the kegerator.)

Next I attached the shell of the stainless steel trashcan to the plastic bottom with bolts. Then I attached the coil to the inside of the shell with metallic tape. (After doing this I briefly plugged it in again - it still appeared to work.)



I used the remainder of the black plastic trashcan, along with part of a five gallon bucket to make the inner lining of the kegerator. You can see it on the left side of the picture above.

I inserted the cooling plate into the inner lining and began filling the gap between the inner lining and the stainless still shell with spray foam insulation.

This gets me to where I'm now at - the main body of the kegerator is together with insulation nearly to the top inside. Here are a couple of pictures of what it looks like so far:





After I finish up the insulation, I'm going to build a small box over the compressor that will have a hidden shelf to hold a CO2 tank. I plan to install a digital aquarium temp controller to maintain its temperature (I ran the probe threw the back with the line for the cooling plate - it pokes through the inner lining across from the cooling plate.)



After I'm done with the main part of the kegerator, I'll build a top (probably tiled) that has a tap in a black metal tower. Hopefully I'll get this done in the next weekend or so - my goal is to have it completely done before Labor Day.

This looks like a great alternative to the box extenstion on a mini fridge.
