This product is designed to cool a beer tower on a direct draw type draft beer system. 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 less than 5 minutes away - just install this tower cooler. It 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. Installs in minutes with no tools!
