What is a Kegerator?

A kegerator is a device used to dispense beer from a keg. It is essentially a refrigerator that has been modified to hold kegs and dispense beer through a tap.

Kegerators come in various sizes and designs, but they all have the same basic components: a refrigeration unit, a tap, and a CO2 system.

Advantages of Using a Freezer as a Kegerator

One advantage of using a freezer as a kegerator is that freezers are typically less expensive than kegerators.

Another advantage is that freezers have more insulation than kegerators, which means they can hold temperatures more consistently.

Additionally, converting a freezer into a kegerator can be a fun DIY project for beer enthusiasts.

Steps to Convert a Freezer into a Kegerator

Choosing the Right Freezer

The first step in converting a freezer into a kegerator is choosing the right freezer. You’ll need a chest freezer that is large enough to hold your kegs.

Make sure to measure the inside of the freezer and compare it to the size of your kegs to ensure that they will fit.

Installing a Temperature Controller

The next step is to install a temperature controller.

A temperature controller will allow you to set and maintain the temperature inside the freezer at the desired level. You can purchase a temperature controller online or at a homebrew supply store.

Building the Collar

The collar is the part of the kegerator that holds the faucet and shank. You’ll need to build a collar that is the same size as the freezer’s opening. The collar should be made of wood and insulated with foam board.

Installing the Faucet

Once the collar is in place, you’ll need to install the faucet. This involves drilling a hole through the collar and attaching the shank and faucet. You’ll also need to attach the beer and gas lines to the keg.

Important Considerations

While using a freezer as a kegerator can be a great way to save money and have fun, there are some important considerations to keep in mind.


Make sure you have enough space for the kegerator. The freezer will take up a lot of room, so you’ll need to make sure you have enough space for it and for the kegs.


While freezers are well-insulated, you’ll need to add extra insulation to ensure that the kegs stay at the right temperature. You can


Make sure the kegerator is properly ventilated. Freezers are not designed to be used as kegerators, so they may not have enough ventilation. You’ll need to make sure that there is enough space around the kegerator for air to circulate.


Condensation can be a problem with kegerators. Make sure to insulate the collar to prevent condensation from forming. You may also need to use a dehumidifier to keep the air inside the kegerator dry.


It’s important to keep the kegerator clean to prevent bacteria and mold from growing. Make sure to clean the lines and faucets regularly and sanitize them with a beer line cleaning solution.


Using a freezer as a kegerator is a great way to save money and have fun.
