I have a converted chest freezer kegerator that (years ago) was building up with condensation. Literally, standing water. At that point, I had not added a collar, so it’s not like it was a major air leak. The seal was factory tight.
I looked for solutions and finally settled on the Eva-dry EDV-500. This uses a renewable desiccant material.
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.
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 Top Find Fast Weigh MS-500-BLK I measured out right at 104 grams. 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.
I’ve had this same unit since October of 2008. This trial took place around August of 2013. As of this edit (March 2015), this unit is about 6 and 1/2 years old. Other than a slightly curling label, this looks like new and it certainly works like new.
The Eva-Dry EDV-500 has kept my kegerator dry for years. It is a Top Find and I’m glad to have it!
