I use a converted chest freezer as my kegerator/keezer. With the aid of some modifications like a collar and an overriding thermostat, it works really well. The big downside I’ve experienced is… condensation. Not just beads of water on the sides, I had pooling water in the bottom. Not a good thing. This varies by how often I’m in it, the season and current weather, but the fact is, a chest freezer just isn’t designed to deal with condensation like a refrigerator is.
Enter the Eva-Dry E-500. The Eva Dry contains a desiccant material that absorbs moisture. The beads inside this unit absorb moisture. As they do that they change color. When they have gone from blue to pink, you know it’s time to “renew” the unit. This is done by removing it from the kegerator and plugging it into an outlet. The integrated heating element drives off any built up moisture. When the beads turn blue (overnight), you’re ready to go. I don’t have to do this often, usually every couple months.
Trial: I recharged this unit on June 22. I’ve known that this works, but I wanted to put some numbers to it. Pictures and testing were completed in my collared deep freezer based kegerator.
Here’s what the beads looked like on August 10th. The beads are what I would call and translucent pink-ish. I left the unit in place for another week to see what would happen with moisture content. It predictability… continued to get worse. On the 18th, I recharged the unit and wiped down the inside of my kegerator to test conditions without the Eva-Dry in place.
This picture was taken 8 days later at my first weekly test. This is what I would call a similar level of moisture after only 8 days vs 49 days with the Eva-Dry. I have no doubt that water would end up pooling in the bottom of my kegerator, in relatively short order, without the Eva-Dry in place.
I took the final weight of these on 8-17. My Escali Primo has it coming in at 876 grams.
Using my Fast Weigh MS-500-BLK I measured out right at 104 grams of water. I used the tare feature so this is actually 104 grams of water. It nearly fills a taster glass. This represents what the Eva-Dry absorbed and the water that would have otherwise been sitting in my kegerator.
I’ve had this same unit since October of 2008. This trial took place around August of 2013. As of this update (February of 2018), other than a slightly curling label, this looks like new and it certainly works like new.
The Eva-Dry E-500 has kept my kegerator dry for years. It is a Top Find and I’m glad to have it and can confidently recommend it to you!

Troubleshooting: Still having problems? Many, many HBF Readers use this unit to handle kegerator condensation issues. I’ve recommended it for years and used it in my own kegerator for years. I hear mostly great things back from people. Periodically, I’ll hear that it didn’t fix the problem. I’m convinced most of these cases are capacity related. If you’re still having issues, check out the recommendations below.
Some things to consider:
- Make sure your kegerator is as tight as possible. Put a flashlight on the inside and (in a dark room) look for light. Add weather stripping or insulation to problem areas.
- Add a recirculating fan. A recirculating fan isn’t going to take any moisture out of the air. It is going to blow it around. The thing it should do is make the absorption process more efficient. Consider this fan – via Amazon [Related: Kegerator Beer Line Temperatures & Reducing Foam with a Recirculating Fan] Thanks to HBF Reader John for this tip! John uses this fan – via Amazon
- Consider adding something under your kegs to increase airflow. I use San Jamar Interlocking Bar Mats – via Amazon. See: Upgrade Your Kegerator – 6 Improvements
- Capacity Issues: If you’re still having condensation issues I would suggest adding another unit. There is no doubt the Eva-Dry E-500 absorbs moisture. After that it becomes a question of capacity. An illustration – If I spill a half gallon of water and put a single paper towel on it, it would immediately soak the paper towel and leave water behind. I could say, “paper towels don’t work.” It’s not that paper towels don’t work, they do work. I just didn’t use enough paper towels to address my problem. If everything else is right and you’re still having condensation problems, I am suggesting that you should consider adding more absorption capacity in the form of an additional unit.
