A keg, typically of beer, is stored in a refrigerated container in order to keep the keg chilled. The user is able to maintain a tapped keg in such a device for extended periods of time, usually a couple of months, without losing any quality in the taste of the beer. A kegerator may be purchased in its finished form or built from a re-purposed refrigerator or a freezer with special equipment.'''Parts of a Kegerator* tank* Regulator* Coupler* Beer & Air Line* Tap* Tower* Drip Tray* Faucet* Faucet HandleOne crucial part of a kegerator is a coupler. Beverage dispensing devices, such as the kegerator, have many standards for couplers:* System D (US Sankey) - Standard for American beer* System S (European Sankey) - Common for European beer* System U - Used for stout and ale by a few breweries in UK/Ireland (Guinness)* System G - Used by some breweries in UK/Ireland. (Also used in the US by Anchor Brewing).* System A - Chiefly used by breweries in Germany.* System M - Used by some German breweries (Schneider)* Pin and ball lock home brew keg taps - Designed to work with Cornelius kegs.The D, S, U and G couplers are secured by twisting them in place (like a screw). The A-coupler is often referred to as a "slide coupler", because unlike the other couplers it slides in place and can be secured at any angle. (The M-coupler is also a slide coupler).
