Kegged Beer Cooler: Complete

Published March 3, 2011

The kegged beer cooler is complete, sitting in the basement, and is actively cooling what remains of two kegs of beer. Tonight I ran the gas lines, fitted everything into place, and set it up against one wall of the basement. It’s currently set to start cooling at 40°F and shut off at 35°F ambient temperature in the unit, which I expect to keep the beer at somewhere in that range. It may be necessary to narrow the band to something a bit narrower, but I’ll be able to determine that after putting a full keg of beer in the freezer and monitoring it.

I’ve been considering fitting the fridge with taps, but for the time being I think I’ll just stay with using picnic-style taps inside the unit. Actual beer faucets are around $100/each after considering all mounting hardware, and I don’t think they’ll provide enough benefit to justify doubling the cost of the unit.

Here’s some more notable photos of the unit throughout its progress:

· Completed chest freezer to beer keg conversion.
· Looking inside at two corney kegs, party tap-style dispensing lines, gas lines, temperature sensor, etc.
· Gas line transition from the compressor compartment into the body of the freezer. It is held in place with twist-type reusable cable ties.
· Temperature probe in place and gas line and Y fitted. Excess foam was left in place to serve as a hose guide.
· Operational Johnson Controls A419 temperature control indicating that it is currently cooling.

All of the photos can be found here. And yes, Roxie approves of it.

Temperature Control Fitted

Published March 3, 2011

The temperature control for the kegged beer cooler fitted and it seems to work. It started, cooled the unit until the appropriate temperature was reached, then turned itself off. Now I just have to run the gas lines and see how it goes with actually cooling beer. This will require a little bit more hardware, although I’ll probably only fit it out for two kegs for the time being, as that’s how many I have. It’s too bad that my current kegs are also almost empty, as I won’t be able to run it fully loaded. I guess it’ll be time to brew more soon.

I also need to consider monitoring temperature in the unit or attaching the probe to a specific keg. I think that in the unit will be sufficient, but for the first couple weeks I’ll double-check this by occasionally checking the temperature of a keg itself.

New photos from tonight’s work are can be found on this page.

(Yes, I know those screws are too long, but they are what I had laying available. Oh well, they neither interfere with anything nor will they be seen once the unit is closed up.)
