I'm having issues keeping a consistent temperature in my kegerator. I already have 2 muffin fans installed to circulate air across the kegerator and up the tower, but am still having temp problems.

One idea I had was putting a 1 1/2" PVC pipe in the dual tap tower and surrounding it with that spray foam insulation. Has anyone tried this? Any reason why I shouldn't try it?
 
I saw that idea on a bar build web site. I would think it takes away valuable room for hoses and makes the air transfer tougher. What I did was use a piece of that foam thin sheet packing material, formed into a tube and shoved it into the tower. There is a small hose that runs up the tower from down below. The end down below is in front of a small 12v. fan. Seems to do the job and I don't get the annoying condensation on the outside anymore. :mug:
 
I tried to insulate my tower with great stuff spray foam. It was just the normal arasol can you buy at Home depot or lowes. Apparently it needs contact with air to cure, as only the outer layer was entact, below that it didn't set up. I would think you could do several layers, with time to cure between each application.
I ended up insulating my tower with neoprene, which I cut from a cheap yoga mat.
 
just buy that cheap black "pipe wrap" insulation. much like a "pool noodle" but you can get different diameters that can surround your taplines and keep them well insulated...they are easy to remove too, as they are split down the sides. They are nice and flexible as well, so you could insulate your lines all the way from the keg up to the tap spigot.

Here's the quickest fix.

Take a roll of paper towels that has been used enough to just fit inside the
tower. Run the lines up through the cardboard inner tube.

Depending on the height of your tower, you may have to take a hack saw or something to shorten the paper towel roll.

I've used this method of insulating since day on and it makes removing it to get in an fiddle with the shanks much easier.

That's a good idea...I've actually got a leftover piece of that stuff that came with my new water heater, and it looks to be about the right diameter.
 
Thanks for all the great ideas! Pipe insulation sounds like a much better idea (and less messy) and probably has a similar R value to the spray foam insulation.

I had to duck tape mine together. The slit had enough to let the air out along the sides, and not to the tower. Works great.
 
was wondering if anyone built the tower cooler using a box a muffin fan and some tubing to push the cold air into the tower and let it settle down or push the hot air down? i know i had seen a thread on it with pics and all. below is a post i found that describes it.

Parts needed

1 project box- radio shack about 8 dollars, get the large one
1 compuer fan- I got one from my wife(shes an it) had 3 wires rd/blk/yel
1 bag of RV septic tubing- got mine from a northern tool store got 30 feet for 15 bucks
1 cell phone charger- all chargers have volts and amps rating on the plug part.
more amps and volts = faster fan speed
4 misc screws- go from project box to fan to hold fan on box
1 hole saw kit- I got 2 inch hose so I used 1 7/8 hole saw and for fan 1 hole saw
1 order of patience.

My Fan face was 3 inches in diameter so I used the 1 inch hole saw and cut 4 holes in like a square and filed out the edger so I had like a 4 leaf clover then flied the edges. Then on the side of the box I drilled 1 7/8 hole for the rv hose to go in. It was 2 inches but had a sprial egde on the ouside so the hose screwed into the samaller hole. I then put the fan over the cloverleaf hole and marked the holes to drill to hold the fan. I had some torx screw s that tapped the hole and tapped the cpu fan and held good. then I placed the box at the bottom of my sanyo 4912 and measured to the top if my tower. cut rv hose to length and an extra 1/2 inch. screwed 1/2 inch into project box and before top of fridge I cut a slit and fed my beer line thru to the fittings in the shanks and taped up slit. I then took the charger and routed it thru the drainage port from the outside to the inside. then cut the ends of charger and fan to expose wires. I got lucky and spliced the charger wires with the blk and yel fan wires and it pushed air thru to the project out to the end of the rv hose. plug in fan 10 min before first drink and no foam till last pour.
 
How big is the keggerator? When my keezer is half full I get temp swings, all I did was add more cornies to the group for more thermal mass and I am good to go
