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.
