So, I’ve almost completed work on refurbishing a Beverage Air DD68 direct-draw beer refrigerator I found on Craigslist about a month-and-a-half ago. I did some pretty extensive work to it (see below), putting in about 80-90 hours. There is still some exterior work to be done, and gas/beer line to be added, but it is functional and is being used right now for temperature-controlled fermentation.
Notes on fermentation:
So, in the configuration its in now, I have a Fermwrap heating element (with a homemade foam blanket) plugged in to the Ranco ETC coming into the back. I did this so that I will be able to keep the cabinet at serving and/or lager temps, while still being able to ferment ales, at the higher temperature they need. I know this is really energy inefficient, but it works for now. The fridge stays around or just below ale temps naturally, which is great. I generally don’t need to have the fridge operating at all right now.
Notes on CO2 line:
While I don’t keg yet, I wanted to have the option to later on. I bought a three-stage secondary regulator so that I can use the first two lines for force carbonating. The third line will feed into the three-line distribution bar and be used for serving.
I’ve never really done anything like this before. I’m a big fan of learn-as-you-go.
