Keeping Keg Box Cold

[Anonymous]

I am having problems with my Keg Box. I had the box at a nice 30 degrees, but when I bought my keg and placed it into the box, it now wont drop below 40 degrees. I think I have it well insulated, and have a small fan blowing on the freezer tray and another blowing the air around in the box. The fans are the plug in type and cords are surrounded by great stuff insulation where they leave the box. I had 2 kegs in there in the past and never dropped below 37 or so degrees, but for some reason, this time the temp wont drop. Any help would be greatly appreciated. 😳

A few tips:

1. You did insulate UNDER the floor, right?
2. All seams sealed tight?
3. If frost is on the freezer plate you are good to go. If not, you have a fridge problem.
4. Be sure air is flowing around inside the box. Sometimes if you place the keg right up against the side, you do not get proper air flow. Be sure there is at least an inch gap all around the keg sides.
5. Check your temp probe position, it should hang just above the top of the keg.
6. Add one more fan if needed.
7 . Stop peeking inside…opening the door does not help the cool down process.

I have done all the above, and there is frost on my freezer plate, just cant seem to get temp below 40 degrees, even though before keg was put in, it was 30 degrees, have plenty of space around the keg and thermometer is sitting on top of keg. I am clueless and frustrated.

Don’t let the thermomter touch the keg…it should be hanging in mid air…above the keg. I use one of those digital weather thermometers with a wired probe. The display is outside the fridge so I don’t have to keep opening the door.

If the keg is 35 and the air is 30…then it will just take time for the keg to cool off…if you are using a rubber lined keg, the time may be increased due to the insulating properties of the rubber…the heat transfer is just not as good as with the metal kegs. There is a lot of mass to cool.
I’ve never had much luck with rubber kegs and I always ask for metal.

It sounds like you are doing everything else properly.

Remember if there is frost, then you have 32 degrees. Now it’s a matter of moving air, proper insulation and time. No magic involved, just physics.
