I was curious as to how well my EvaDry 500 was working in my keezer. I still get small puddles of condensation and my DampRid container still seems to be collecting moisture as well (I had a refill so figured I'd use it) Currently it just sits in the bottom, but at some point I plan on configuring the airflow to blow across it. But that isn't really the point of this post.

Yesterday I pulled it and the crystals were pink indicating that it is time to recharge. I decided to weigh the unit to see about how much moisture it really captures. Full weight = 841g, recharged weight = 767g, difference 74g. This comes out to about 2.5 fl oz of moisture. That's not really enough for my setup considering the humidity in North Texas and I will be relocating to an area that has just as much humidity soon.

From here I don't know what I am going to do, add more EvaDry units and maybe stagger them so only one needs a recharge every other week? I've thought about the "bake to recharge" style units, but I don't like the idea of running the oven for 3 hours. I'm using picnic taps, so the lid is getting opened fairly often. Maybe the performance will be better when I get proper faucets.

Have others been happy with their EvaDry units?

Maybe you could set your freezer a little colder so the condensation just freezes and you could just chip the ice off every now and then. This is what I do. I've been meaning to rig a fan setup just to regulate the temp between the top and bottom of the freezer, but haven't made the effort to do that yet.

I have two of the Evadry units. They aren't that effective for me.

I just keep the freezer cold enough to freeze the condensation and then brake it out when it gets too big. Speaking of... it's about time for that and a swiffer wet cloth wipe down.

How cold are you pouring your beer if you get ice build up?

I tried chemical based dehumidifiers years ago and gave up on them for use in my freezers that house my barrel collection.  Have been using several of the Eva-Dry 1100 Petite dehumidifiers.  These are very small electric units I put in my 20 cubic feet plus freezers. I set them with timers to come on/off during the day.  I have been most pleased with their performance and durability for an inexpensive little unit.

Looked at those JJ, I'd likely need to give up keg space if I went that route. Right now I have a space in the back corner about half a keg wide due to needing to offset the kegs. I do like the pint capacity. Any danger in spilling if I had to reach in for it behind kegs to empty? Does it auto shutoff if full?

Might be worth a shot.

That's what I did in the Midwest, recharging one per week with two units. Even that might have been overkill. I think opening the freezer is your main problem.

Cold enough that I don't get foaming in the remote tap box, never measured it. A finicky system, mine is. If I had to guess the 32F at the bottom corner of the freezer equates ti 36-38F beer out of the taps - but that's just a SWAG.

With so little space left, it could partially be related to airflow. Maybe you have some corners that aren't getting air flow and are relatively stagnant? Then again, that's not a lot of moisture it's picking up.

If you took 4 tablespoons of water and dropped them on the bottom how does that look compared to what you end up with naturally today? If it's seems like the same or less water pooled up, another unit in an opposite corner could make the difference.

Just ran to Home Depot to rig up my airflow. I already had the dual USB fan. I picked up a 3" elbow with a 2" side inlet and added a 2 foot 2" downpipe. I might cut the pipe down as it is only 2 inches off the bottom, but the coldest air is at the bottom.

The USB fans supposedly push as much air as a 12v model, but I am unsure about that. I might opt to switch out to two 12v fans wired to a 12v switching wall wort.

One thing I am concerned about is the fans fighting each other, so I may install some sort of baffle in the middle of the elbow.

Neat idea.

My temp controller is set at 38F, the probe is set in the middle of the kegerator on the freezer hump. The beer comes out around 38F, give or take (I think, haven't measured in a while). But it freezes down at the bottom and I'll just chip it off when a keg is emptied and pulled out. I would like to rig up a fan system someday though.

I tested it last night using a match and it pulled the smoke from about 6" away.

I just placed an order for two new fans. I went with 92mm 12v which should fill out the opening just about perfectly. They are also crazy high flow at 3500rpm pushing 60+ cf/min. The reviews all complain about the noise, but I figure they will be inside, so how loud could the be.

The new fans operate at .25A and the power supply I have can handle 2A, so I might add two fans at the bottom with a second elbow. Adding additional fans to the bottom blowing in will increase the pressure and in turn might increase the flow a bit.

I'll report back Wednesday when the fans arrive.
