A kegerator turns a fridge into a draught beer system. Whether you want fresh pours at home or a compact setup for a small venue, the right unit keeps the keg cold, the gas connected and the beer flowing properly. This guide explains how a kegerator works, how to choose between a keg fridge and a miniature kegerator, and what to check before you buy online in Australia.
How a kegerator works
A kegerator has four main parts: a refrigerated cabinet, a keg inside it, a CO2 cylinder with a regulator, and a beer line that runs to a tap. The gas pushes beer out of the keg, the cabinet keeps it cold, and the tap controls the pour. If any part is poorly matched, you get foam, flat beer or slow pours.
Keg fridge or kegerator: which term matters?
A kegerator fridge and a keg fridge are often the same thing under two names, and the words are used loosely, and shops use them differently. What matters is the specification. A keg fridge is usually a cabinet big enough for a keg, and a kegerator adds the tap, tower and gas fittings. Browse our kegerators and dispensers to see complete units and compare what is included.
Size and keg compatibility
Common keg sizes include 50 L, 30 L and the smaller 19 L Cornelius-style kegs used by home brewers. Not every unit takes every size, so confirm the internal height, width and depth against the keg you plan to use. If you are buying for a venue, think about how many different beers you want on tap at once, because each tap normally needs its own keg and line.
Miniature kegerator for small spaces
A miniature kegerator suits an apartment, a small home bar or a staff area. It takes smaller kegs and has a smaller footprint, so it is easier to place and cheaper to run. The trade-off is fewer pours between changes and less flexibility on keg size. If you drink a lot of draught, a bigger unit may suit better.
Choosing a refrigerator for kegerator conversions
Some buyers pair a standard fridge with a conversion kit. If you take that route, choose a refrigerator for kegerator use that has enough internal space, a stable thermostat and a solid door. Make sure the shelves can be removed and the compressor is not blocked by the keg. Purpose-built kegerators avoid these compromises and usually include drip trays and proper tap towers.
Taps, towers and lines
A beer tap and tower sit on top or on the front. More taps allow more beers but need more kegs and gas lines. Keep lines short and clean, because long or dirty lines cause foam and off flavours. Cleaning kits and replacement parts are listed in our accessories and parts range.
Cooling and temperature
Draught beer is best served cold and steady. A thermostat that holds temperature, good insulation and an unobstructed condenser all help. Avoid putting the unit in direct sun or a closed cupboard, and check the climate class if it sits in a garage or outdoor area. Our beer and beverage fridges also suit bottled and canned stock.
Gas, regulators and safety
CO2 cylinders are heavy and must be secured upright. Use a regulator set to the pressure recommended for your beer, and check for leaks with soapy water rather than a flame. Store spare cylinders safely and keep them out of direct heat. If you are unsure about gas fittings, ask a qualified supplier.
Home use or venue use
A home kegerator pours a few glasses at a time and sits in a games room or garage. A venue unit pours all night, so it needs stronger cooling, a robust tower and easy cleaning. If you plan to serve guests regularly at home, think of it as a small venue and choose accordingly. Our venue guides show typical home bar setups.
Cleaning and maintenance
Beer lines should be cleaned on a regular schedule with a line cleaner, and the tap and coupler rinsed. Clean the cabinet interior, check the door seals and keep the condenser free of dust. A kegerator that is looked after pours cleaner beer and lasts longer. Cleaning supplies are listed in our covers and cleaning category.
What affects the price
The cost of a kegerator depends on size, cooling capacity, the number of taps and the build quality. Commercial units cost more than compact domestic ones. Compare what is included, because a lower price can leave out the regulator or the cylinder. Look at the total cost of the full setup rather than the cabinet alone, and ask for a delivered price through the quote form if you are buying more than one.
Buying a kegerator online
Before you order:
- confirm the keg sizes the unit accepts
- check what is included: tap, tower, regulator, coupler and drip tray
- read the warranty and delivery terms
- measure the doorway and the final spot
If you are buying more than one unit for a venue, send the details through the quote form. For a fridge to hold bottled drinks alongside the keg, see our best bar fridge guide or our beer fridge guide.
Frequently asked questions
What is the difference between a kegerator and a keg fridge?
The terms are often used interchangeably. A kegerator is a fridge set up to store and dispense draught beer, while a keg fridge may simply be a fridge large enough to hold a keg.
What size keg will a kegerator hold?
It depends on the model. Compact units take small kegs, while larger commercial cabinets take full-size kegs. Always check the internal dimensions and the keg sizes listed on the product page.
Do I need a CO2 cylinder?
Yes. Most draught systems use CO2 to push beer through the line. You also need a regulator and the right coupler for your keg type.
Can I convert a normal fridge into a kegerator?
It is possible, but a purpose-built unit is designed for the job, including drip trays, tap placement and the cooling needed to keep beer at serving temperature.
