Cold does not rise. When you have a beer tower atop a refrigerator, even if you have a 3" hole connecting the two, the beer in the tower lines will warm between pours. This simple hose/fan assembly features a low voltage fan for safety, that pumps low velocity cold air up from a refrigerator into the base of a tower through a 30" long ¾" diameter flexible hose. The included low voltage transformer has a 54" long cord, so you can plug it in outside your kegerator when it is time to dispense.
Keeps your beer cold between pours, and uses less than 15 watts. Note that this model is not silent, and makes a fan whirring noise when on, which can be heard close by in quiet environments.

Q: Does this have an on/off switch? My available outlet is behind my kegerator so plugging it in and out is not convenient. Thx
A: There is no on/off switch.

Q: Does the power cord disconnect from the unit so I can thread it through a small hole in the kegerator? I can't tell from the pictures.
A: Yes, the power cord is an AC adapter which plugs into the cooling unit.

Williams Brewing is the best
My first fan didn't last long, the power supply showed the proper voltage, but just couldn't run the fan. They sent me a replacement and everything is working perfectly now. Thanks for standing behind your products!
Tower cooler
The first pour is perfect every time now! Product is a bit larger than anticipated, but well made, simple and extremely effective. Beers have never been happier!
