Hey Guys,

New owner of a Marvel Kegerator. 3rd owner.

It has a resting temp of approx 37*F. Got a cheap keg of PBR just to work out the quirks. After replacing the beer line and letting the keg set for several hours I was getting about 4" of foam on first pour and subsequent pours are just fine.

Built a tower cooler today initially had the fan by the cooling plate but then the tower was pouring @ 37.3 and the liquid temp in the kegerator was 40*F. I then moved the fan down by the keg and now the temps at the first pour and liquid temp are about 1*F off. Still getting some foam but the tubing I have now is 1" and too big to bring to the top of the tower. I don't want to use a hole saw just yet but I'm looking for suggestions for 1/2" flexible tubing to replace what I have now.

What about these?

Is 1/2" big enough to allow air movement with an 80mm fan connected to a 9v power supply?

If that doesn't work should I widen the hole underneath the tower?

If the faucet was dirty would all pours be foamy?

Just got back from Lowes with vinyl tubing 1"OD, seems to work better than the corrugated stuff from earlier.

I was able to place the end right under the shank, albeit it fits snug through the top of the kegerator but seems like there is enough room to allow air to fall back into the kegerator.

I'll check the temp for a few hours and then report back how things went.
 
A couple more feet of line would help with the foam but keeping the faucet cold is the key. Sounds like you did well. You might notice the first pull, even at bars, has some foam they drain off into the drip tray. I'm a little more stingy with my brews.
I think the coiled thing you linked is just a coil, not tubing. The commercial units use a 1" tubing that looks like that but is wire reinforced and when I've tried to buy it it was quite spendy. http://www.micromatic.com/draft-keg-beer/air-cooled-pid-1651.html
