The number one complaint about any direct draw kegerator is that the beer faucet & shank get warm and your first 1/2 glass of beer is always foamy. But the solution is easy - just build and install a beer tower cooler. This tower cooler works by continuously blowing a small volume of cold air into your beer tower and the cold air keeps your beer shanks and faucets ice cold. A side benefit is that the continuous cold keeps faucet mold and bacteria growth at an absolute minimum.

It's easy to tell if you need a beer tower cooler. If your first glass of beer is always foamy but the next glass is not then you need a beer tower cooler. And here is what's going on:

Between servings your beer tower shank and faucet are warming up to room temperature.
Then when you serve your first glass of beer the cold beer hits the warm beer shank and creates beer foam.
Because your beer shank and faucet were cooled by your first glass the next glass and any glass after the second glass have less foam.
Then when you stop serving for a while your beer shank and faucet warm back up, starting the cycle all over again.

Step 1: Bill of Materials

Here's what you need to build your own beer tower cooler.

$53.11 - Total plus your local sales tax rate - any parts you might already have laying around

If you plan to substitute the most important part is to stick with a 40mm micro fan. Larger fans push too much air into your beer tower and they cool too well, causing your beer faucet to constantly sweat. You want to cool your tower enough so that the outside of your faucet is about 10 degrees F lower than your room temperature. Your beer shank and inside of your beer faucet will be quite a bit colder and will be cold enough to greatly reduce beer foam.

<p>I like your design, I will be making one in the next couple of weeks, just waiting on the delivery of my keg fridge. I believe you could use a larger fan but maintain the same air volume transfer by keeping the intake hole at the design's 1 3/8&quot; diameter.</p>
