Cedar Rapids Brewing Society

At work we are disposing of an old IBM storage device. I pulled a few fans from this to provide some circulation in my keezer. they are prob
ably 5-6" in diameter, brushless pc type fans, w large plastic bracket and pigtail. if you would like one or two of these let me know by Thursday at noon and i can do my best to get some for you. Thurs noon is when its being disposed of. i would guess the fans are 5 yrs old, have no clue to the db level or anything. I'll find out after I rig em up in my keezer.

I'd gladly take a couple.  -Jim

I'll take a couple.

I have enough right now for you two guys. If anyone else wants any let me know. These would work well for a stir plate project too. I'll just do first come first served here, and will try to send em to the meeting on Thurs. I have to work that night so won't be able to make it but may be able to convince Dave to grab them on his way up. Otherwise if people are meeting at 3rd Base on Dec 1, I can take them then too.

The fan is a 5" fan, the metal assembly is 7". You can snip the connector off the pigtail and hook up an old cell phone charger to it and make a nice low voltage fan. They would probably go for $20-25 at a place like Midwest Electronics. I got em for free tho, and am sharing them for free.

Here's what we're looking at. If anyone else wants some, I think there are 10-12 left.

I take a couple as well.

I hooked one up to an 8v dc adapter and it pushes out some nice air with low noise. One should do nicely in my 10 cu ft keezer. As I said before, I think it'll be awesome for a stir plate too.

Hey if you still have some available I could really use two of those bad boys!?

I would take one as well. What are you doing with it in your Keezer? Just distribute the air evenly?

Ok, I should have enough for everyone that's posted here.

Exactly. I consistently get foam out of one of my lines, and I'm positive that its temp related, since its the one in the corner. So going to get this to help out with that, and just to get consistent temps throughout.

Dispensing beer properly can be as scientific as making the beer. I spent quite a bit of time on my fridge last time I replaced the lines figuring out temp, inner diameter, length of lines, pressure and the relation of the tank placement to the taps, etc. I still get inconsistent pours based on the keg.

Do you have a longer draw system where the lines run out of the keezer and to the wall of some sort, I know commercial systems use fans to draw cold air from the cooler over the lines to the taps. That is what I thought you were originally looking to do. Rapids in Marion sells the special lines that allow cool air to run over the beer line and under the insulation.

I just have a typical collar setup with 3 taps. The one tap in the corner always serves a glass about half full of foam. I've switched hardware, lines, kegs, etc. It consistently serves with extra foam in that location only. It seems like its a warm spot or something, that's my only guess at this point. So I'm going to install the fans to see if that helps. If not, no biggie, I rarely have 3 beers on tap at once anyway, so I hardly use that one. Usually just two, tops. Worst case, I should now have even temp distribution throughout my keezer.

You've probably already checked this, but could a pinched or restricted line be causing the foam?

Oh snap, I just remembered this, its been so long since I've used that side, I've just forgotten. But it was always and only the first pour that was half foam. After that (in the same sitting) it was always ok. So that's why I think it was a warm spot.

So here is one of the applications for this fan. I'm going to make a stir plate out of the other. Those of you who asked for one or two, PM me and we can share info. You can swing by and pick them up or maybe arrange something else.

Anyway, i'm getting pretty good air movement out of these. I used a large nut as a stand-off to allow for some air flow. i just screwed it right into the lid. For the size of my keezer (10 cu ft) it works great for equalizing the temps throughout. I used a thermometer and was almost spot on at the top and the bottom.

I'll be bringing these fans to the meeting tonight. Those that spoke up earlier, if you're there you can snag em. If I have any extras I will bring those and share as well. I don't remember off the top of my head how many I have at home.
