Freezer condensation

How do you control the condensation in your keg freezers?  Mine is getting a bit damp inside. 
Thanks

I use a four pound tub of Damprid in mine.

Yup.  DampRid.

Of course.  Can’t find it in Canada. Did a google search and searched at Home Depot’s and Wal-Mart’s websites and neither listed it.  Tried the DampRid website store locator.  Nothing within 100 miles of my postal code (nothing came up at all to be honest).  Guess that’s something I’ll have to try to find next time I’m in the US.  I did see that they will ship but most of the time, when I get something shipped from the US, it costs me 5X in brokerage and shipping fees so it’s never worth it.
Thanks for the suggestion though.

Damp rid works but gets expensive after a while these you just keep on using by just plugging them in to recharge them.

If the link no longer works, just search for Eva Dry dehumidifiers. I haven’t bought mine yet, but I will soon. I just set up my keezer. Some guys in my club swear by these.

If he can get those easily then I say go for it, but I would need two and I haven’t spent $44 on damprid over the last several years combined, more like $15.  But how fast you go through it probably depends a lot on the humidity of your area, the seal on your freezer, and how often you’re opening the lid.

I’ve also heard and seen some some folks using fans to help dry out the condensation.

I don’t see a fan changing the relative humidity in a closed space. You need something to absorb the moisture so you can remove it. There’s a lot of moisture that gets thrown off from the fermentation buckets I have in my fermenteezers… May try damp rid, although just mopping it up once in a while works too. The older one is starting to show some rust though…

I actually have the Eva Dry product in my keezer…it am not totally impressed by its performance, but I never used damprid so I don’t have a good comparison.  It would work better if I had a small fan moving air in the unit.

It does absorb moisture and lasts about a month (the weight difference when you take it out to recharge is noticeable).

Yes. I think it’s done in conjunction with the use of a desiccant like damp rid. I have no personal experience with the use of a fan but there are reports of it’s abiltity to mitigate condensation.

No firsthand experience, but I would think that in hot and humid climates (like Florida) the vapor pressure would defeat anything accomplished by a measly computer fan and the hole made to accomodate it…  I would think that one would be better off keeping the keezer airtight and using a dessicant (like DampRid).

I remember an architect who designed surgery centers in Florida (where condensation is a common problem given 99 F and 99% humidity outside, and code-mandated climate of 68-73 F and <50% humidity inside the surgery center) telling me that 8 gallons of water a day can pass through a hole the size of a quarter.

Keep it sealed and airtight.  Dry out the keezer from within.

Haven’t tried it but I ran across this last year. It suggests using a Sham-Wow to soak up condendation.  Might work?

I don’t think the object is to cut a hole for the fan, just to circulate the air inside like Ron mentioned.  I know that my kegs are packed in pretty tight in both of my keezers, so circulating the air will help move any moisture around to where the damprid is, plus level out the temperatures.  I might have to add one, but it’s not a problem really so …

I see what you mean by using a fan to improve air circulation within the keezer and direct the condensation to the damprid. 
Still important to keep it airtight, so “no hole” in the keezer is still the best way to go.

I agree, airtight it really important.  But it’s not going to keep out all of the moisture you let in every time you open it, or when you ferment in it.

In all the reading I have done the main purpose of the fan was to balance the temp from bottom to top.

It would probably make the moisture removal product of your choice work a little better but the big win would be the freezer running a little less.

You took the words right out of my mouth.  :slight_smile:

I agree that temp regulation is important and a fan with help maintain a more uniform temp within the freezer cavity.

Agreed…keeping the freezer airtight will also help reduce even more condensation from the outside air as well.
