Kegerator Forum: CO2 tank froze up!

Posted:  10 Nov 2010 23:53
I,m a rookie at this. 

I converted a 5.3 cu.in. frezzer into a kegerator.  I built a 12.5 inch wood collar to accomodate a door mount perlick faucet. 

I tapped the keg Friday.  I equipped the unit with a Loves Temp controller.  I set it for 40 deg.  After some reading on your website I learned that 38 is the optimum temperature.  The regulator on the 5 lb CO2 tank was set for 12 psi, also via your website I was wrong.  I would have a good pour after the first pour, until last night, Tuesday I poured 2 beers, went back for a third & nothing but a trickle.  My CO2 pressure gauge said empty.  Impossible, so I disconnected the coupler & found ice build up around the seal.  I weight the tank, it weighed in at 8 lbs. and the outside was frosted over about an 1/16 inch.  I let it sit overnight in the house, hooked it up Wednesday morning before work, and it now read full. 

What would cause this to happen?

I'm an idiot. I had my temp probe too high in the keezer.  I lowered it & was able to maintain a fairly good temp. I actually put the probe in a 2 liter coke bottle. Beer is pouring perfect. 37 deg F.

The CO2 bottle didn't freeze, the pony keg did.
