How big of a CO2 tank do I need for a soda machine?

Answered by Matthew Yawn

When it comes to determining the size of a CO2 tank for a machine, there are a few factors to consider. The size of the tank you need will depend on the volume of soda you plan to dispense, the frequency of use, and the space available for the tank.

If you have a lower volume soda machine in a small establishment or even at home, a small 10 lb CO2 tank should be sufficient. These tanks are compact and can easily fit in tight spaces. They are commonly used in personal kegerators, fish tanks, reef tanks, and even blowout kits. The 10 lb tank can provide enough CO2 to operate the soda machine for an extended period of time without the need for frequent refills.

For slightly larger setups, such as in restaurants, bars, or concession stands with moderate soda consumption, a 20 lb CO2 tank would be more appropriate. This size tank is still manageable in terms of space but holds twice the amount of CO2 compared to the 10 lb tank. It can handle the demands of a higher volume soda machine and may require refilling less frequently.

It's important to note that the size of the CO2 tank doesn't necessarily affect the quality of the soda. The CO2 is responsible for carbonating the and providing that refreshing fizz, regardless of the tank size. However, having a larger tank can save you the hassle of frequent refills and ensure a continuous supply of CO2 for your soda machine.

In terms of personal experience, I have worked in a small pub where we had a 20 lb CO2 tank for our soda machine. This size tank was perfect for our needs as we had a moderate soda consumption. It provided enough CO2 to keep our soda machine running smoothly without frequent refills. The tank was also easy to handle and didn't take up too much space behind the bar.

The size of the CO2 tank you need for a soda machine depends on the volume of soda you plan to dispense, the frequency of use, and the available space. For lower volume setups, a 10 lb tank is ideal, while a 20 lb tank is suitable for moderate consumption. Ultimately, choosing the right size tank ensures a continuous supply of CO2 for carbonating your soda and minimizes the need for frequent refills.
