Kegerator is a term derived from the combination of two words, keg and refrigerator, to refer to a draft beer dispensing system to allow you to enjoy a fresh, cold glass of your favorite beer right in your own home. A ready-to-go unit is basically a mini fridge with the capacity to house and refrigerate different types and sizes of kegs depending on the kegerator model and features. By using a kegerator conversion kit you could also convert an old or unused fridge into a kegerator with a bit of research and the right tools.
The sizes of standard kegs available are 1/2 keg (full size), 1/4 (slim and short), 1/6 keg (slim) and mini kegs and the size you require will deem the type and size of kegerator you will want to purchase. For the most versatile results a unit such as the Danby DKC645BLS or EdgeStar KC2000 kegerators that support all standard sizes of kegerators and are designed with flexibility in mind are an excellent choice.
By using a home kegerator you are able to keep a keg of beer chilled to perfection for extended periods, usually up to a couple of months, so you can have delicious draft beer at your fingertips.
