Keezer Condensation
I have a 5 cu ft keezer with a simple 2x4 wooden collar and I'm getting quite a bit of condensation. It caused some surface rust on the bottom of my CO2 tank. Do I need to try to insulate the collar or would putting a fan inside help?

Neither will cure it completely, but both will help some and provide for a better pour. They will allow for more even temp distribution throughout the keezer reducing condensation as well as keeping the beer lines cooler higher in the unit.

it is tough to completely eliminate this problem. Sealing up any air leaks is the best way to minimize it. Use silicone caulk wherever there is a potential gap between surfaces. Also, rigid foam insulation will help. The fan is a good idea too. I also have a small dehumidifier inside mine. It helps a little.. Your location is also important. Mine is in my garage, which makes the problem worse.

Yeah, it's in my garage and it's been so hot and humid this summer so hopefully that's a big part of it. I did caulk the joins on my collar and between the collar and the freezer and I think I have a pretty decent seal on the lid.

I kept trying to search for other threads like this and couldn't find them until I actually posted this thread. Then the similar threads thing at the bottom gave me all sorts of threads to look at.

I think I'll try some DampRid or dehumidifier and maybe add a fan as well.

the fan really helps keep the temps even. It will cause your taps to sweat more though. I recently recaulked my keezer collar after finding about 3 inches of water in the bottom of the keezer. It made a big difference.

Good news is that the hot weather is almost over. Then you'll just need to keep it from freezing. :-)

Definitely insulate the collar and definitely add a fan, as others mentioned that'll help. The fan in particular will help keep the lines cooler and reduce foamy first pours. I'd recommend an Eva dry dehumidifier over the damp rid, they're nice little units and you can regenerate them overnight. Put it on its side right under the fan for the best results, mine's in a hot humid garage and I have no visible condensation. Also try not to open the lid unless you have to, that's the real killer.

I don't have a keezer but how about a couple boxes of baking soda?

I may be able to unplug it and leave it open in the winter. I think my garage manages to stay above 40 most of the winter.

I have one of these in my keezer and kegerator....


Plug in to recharge and they were just on sale at Amazon.
