A device which functions similar to a refrigerator, except it's for beer. Beer kegs are installed, and the pump is pressurized with the aid of CO2. The kegerator has a tap at the top for dispensing purposes. Most kegerators accept quarter sized (7.7 gal) or half sized kegs (15.5 gal). An adjustable thermostat is included to control the temprature of your dispensed beer. Some kegerators have wheels, for ease of transportation.
