Understanding CO2 Tanks for Kegerators

Before we dive into the various sizes of CO2 tanks available for kegerators, let’s first gain a basic understanding of what a CO2 tank is and how it functions within a kegerator setup.

A CO2 tank is a cylindrical container that holds pressurized carbon dioxide gas. In a kegerator, the CO2 tank serves as the power source for dispensing beer from the keg. The carbon dioxide gas exerts pressure on the keg, pushing the beer through the keg system and out of the tap.

CO2 tanks typically have a valve and a regulator. The valve controls the flow of gas into the system, while the regulator allows you to adjust the pressure of the gas. This is important because different styles of beer require different carbonation levels, which can be achieved by adjusting the pressure from the regulator.

CO2 tanks come in various sizes, and the size you choose for your kegerator will depend on factors such as the frequency of use, the number of kegs you plan to dispense, and the available space in your kegerator setup.

It’s important to note that CO2 tanks are refillable, so you don’t need to worry about constantly purchasing new tanks. Most local homebrew supply stores or gas suppliers offer CO2 tank refills or exchanges, making it a convenient and cost-effective solution for your kegerator.

Now that we have a basic understanding of CO2 tanks and their role in a kegerator, let’s move on to discussing the factors to consider when selecting the right CO2 tank size for your specific needs.

Factors to Consider for CO2 Tank Size

When choosing the appropriate CO2 tank size for your kegerator, there are several factors that you should take into consideration. These factors will help ensure that you have a sufficient supply of CO2 for your beer dispensing needs.

1. Frequency of Use: Consider how often you plan to use your kegerator. If you’re a casual beer drinker and only plan to dispense a few beers on special occasions, a smaller CO2 tank size may be sufficient. However, if you frequently host gatherings or have a constant demand for draught beer, a larger CO2 tank may be more suitable.

2. Number of Kegs: Determine the number of kegs you’ll be dispensing simultaneously. Each keg requires a certain amount of CO2 to maintain the desired carbonation level. If you have multiple kegs hooked up at once, you’ll need a larger CO2 tank to supply enough gas pressure for all the kegs.

3. Available Space: Consider the dimensions of your kegerator setup and the space available for a CO2 tank. Different tank sizes have varying heights and diameters, so you’ll need to ensure that the tank you choose fits properly inside your kegerator without obstructing other components.
