Kegerator Upgrades

I recently made some minor functional and major cosmetic upgrades to my kegerator. Functionally, I moved the CO2 tank to the outside of the kegerator. This was accomplished by a brass pipe placed through a hole in the wooden collar with a 90° elbow and a barbed fitting on both ends(Outside: Left, Inside: Right). I placed a washer to take up some slack and to make a better insulated pass-through. This modification was made because I was having troubles with the tank not producing CO2 fast enough, it would sometimes take almost a minute to produce enough CO2 for the initial air purge when kegging (which has to be done 3-4 times). Another reason to move the tank outside is I recently acquired a 2.5 gallon corneilus keg and the mini corny and the gas tank would not both fit in the kegerator. This was an amazing find since these little guys are extremely rare compared to their 5 gallon counterparts. I found this one on craigslist for $75. A normal 5 gallon corny keg sells for between $30 and $40 where a 2.5 gallon one can sell upwards of $150, demonstrating the simple economics of supply and demand.
The cosmetic modifications were pretty major also.
I finally cut a hole for the thermocouple to pass through, it can be seen next to the barbed fitting on the inside of the chest. I finally got tired of looking at it just dangling over the edge. The other modification I made was to clean up the unruly routing of the gas and product lines. The easiest way i could think to do this was orient the kegs so gas lines were on the outside and product lines in the center. This turned out to work great and the results can be seen below.

  1. So you bought something for twice the amount that holds half as much..... I'm confused.

  2. http://www.thebrewingnetwork.com/Beer-Gadgets/The-Portable-Kegerator This is one reason that you would want a 2.5 Gallon keg. Another reason is if you want to give some away you can bottle half a batch and keg the other half. Or you can make a small batch of experimental beer that you wouldn't want to waste an entire 5 gallons on. One other thing you could do is make soda. The possibilities are endless.

  3. couldn't you just fill up a normal keg half way?

  4. You could but the problem is that you need to purge the air out of top so it does not oxygenate the beer and that becomes difficult since there's not a way you can make sure all the oxygen gets out.
