The main component of the barreled beer distribution system is a device that quickly cools the beer flowing through the beer tube through the built-in compressor refrigeration system. It belongs to the beer beverage equipment. A complete set of beer and beverage equipment includes wine barrel, wine spear, distributor, pressure gauge, hose, mini kegerator, wine tower (wine column), wine label and beer tap. Beer or beverage is first drawn out of the barrel or other containers through the spear, distributor, pressure gauge and hose, then cooled by the mini kegerator, passed through the wine tower (wine column), and then came out from the beer tap. In this way, the beer or beverage liquor is more fresh and delicious, and is popular with customers. The mini kegerator is also called the beer seller. It is composed of a refrigerator, a draft beer barrel, and a carbon dioxide cylinder. Its working principle is to use the high-pressure carbon dioxide gas in the carbon dioxide cylinder to press the beer out of the draft beer barrel, so that the beer enters the refrigerator, and then flows out from the outlet nozzle. The beer through the mini kegerator is cool and tastes good. website:http://www.perabrew.com/kegerator/
