Anybody else out there convert a chest freezer into a kegerator, and get a lot of moisture in the bottom of the kegerator as a result? Anybody have any ideas/suggestions for how to deal with the condensation, other than to occassionally run a mop through the bottom of it?
There is a thread on that topic here already, my suggestion would be to review that one. http://beeradvocate.com/community/threads/keeping-the-keezer-dry-inside.110980/
Since then I've considered just throwing some paper confetti down into the bottom of my keezer and dry vacing it up every month or two. The DAMP RID didn't do crap after a few weeks. The EVA DRY isn't doing much for my keezer. The manual defrost knob at the bottom (outside) of the keezer seems to be doing the most good. I'm considering propping up my keezer on the far side and back end with a couple of decks of playing cards so that I can have more water run towards the manual drain. Good luck.
If you put some Damp Rid in and don't open it often you should be fine. Once the moisture is absorbed by the Damp Rid as long as you leave the lid closed and have a decent seal you should not be getting more moisture. Damp rid does need to be replaced once a month or so. You can buy refills and just replenish as needed.
It's critical to seal every opening. Silicone caulk is probably the best product for this, IMO. Seal around all the hoses, the temp probe, etc. and make sure there are no gaps around the lid gasket. The importance of not opening it can't be overstated. If everything's sealed tight, opening it is the only way moisture can get in. I've considered attaching a hose from the drain into a shallow pan of some sort much like the pan under most kitchen refrigerators. For now, DampRid and an occasional cleaning (monthly, give or take) seems to keep moisture and its ugly followers at bay. DampRid collects about a pint of water every two weeks in mine - water that would, otherwise, collect in the bottom of the freezer. It sits on the compressor hump alongside the dry yeast, six packs of beer, and bottles of mixers.
