Help cooling my custom kegerator tower

[arnobg]

So I purchased a custom kegerator because the deal was way too wicked to pass up. This thing was built with great attention to detail however, the tap tower isn't insulated or cooled to the extent the lid is.

Here is what I am working with, looking for any suggestions for the best way to handle this. Basically all that is done is 1/2" holes are drilled going down into the insulated lid extension so the tower is completely closed off. This is creating a pour 10-12 degrees above fridge temps since the lines are 10' on the first pour. To me out isn't acceptable especially since the foam is up to 1 1/2-2 inches on the first pour every time.

fwiw, the jargon around here makes the larger addition a "collar" and the small faucet box on top a "coffin".

I would insulate the interior of the coffin with pink rigid foam, bore one hole through the bottom for a small 12vdc fan (80mm ought to be enough) and another hole at least as big to allow air to circulate between coffin and cabinet. I'd add some kind of down tube to the fan side to pull air from nearer the bottom of the keezer and to prevent air from just circulating between the in and out...

Cheers!

+1 what day trippr said. I made a blower like this one, http://www.draft-beer-made-easy.com/towercoolingfan.html
I mounted it near the bottom and used spa vacuum hose for the duct that runs up into the coffin, http://www.lowes.com/pd_652438-7192...Id=50315947&Ns=p_product_price|0&pl=1&Ntt=spa

Im do not use fans in any of the keezers I have built. I rely on passive cooling to keep the liquid lines cool.

But in your case I do recommend fans because of the size of your collar. Even though the collar is insulated you also need to insulate your coffin. Use plenty of caulk to keep that cold air from leaking out.
