component for the gas in and the liquid out. Economics Kegerators are known to have cost benefits that make them a viable choice over the purchase of smaller cases, such as the typical 6-pack or 12-pack. Generally speaking, kegerators save costs because of their connection with business theories on bulk sales, as well as their savings on packaging smaller cases of beer. Since a keg typically stores large amounts of cold beer, many kegerators have been known to save up to 60% on costs when compared to the same amount of volume in cans and bottles. Depending on the brand of beer, cost savings can be even greater. Conversion kits A kegerator conversion kit allows you to convert an existing refrigerator into a beer-dispensing kegerator. This may be a more economical solution if you already have the refrigerator or you can find a cheap used refrigerator (at a yard sale, classifieds, etc). An important thing to consider is whether or not the refrigerator will be able to hold a keg. Many refrigerators have a step inside them that houses the compressor and takes up half the bottom of the fridge, meaning that there is not enough space above or in front of the step for the keg. Pre-configured kegerators are designed with this in mind and install the compressor in a manner that allows plenty of room. Conversion kits are configured to either dispense through the door of the fridge or through the top into a draft beer tower. Door mount kits have a shank that goes through the door, with an attachment for the faucet on the outside and a hose nipple for the beer line on the inside. A draft beer tower would extend above the top of the fridge and already includes the faucet, shank and 5' beer line. Installation requires a few rudimentary tools, such as a socket wrench set, screwdriver and a drill with a hole saw bit to modify the refrigerator. The CO2 tank can be installed inside the fridge if there is enough room, or placed outside the fridge and secured into place. You can also convert a top opening chest freezer into a beer dispenser (sometimes called a keezer) with the use of a thermostat control unit. The advantage of a Keezer is that you are assured it will get cold enough to dispense beer at the proper temperature range (32-38 degrees
