When it comes to the placement of your CO2 tank in your kegerator, there isn’t a significant difference between having it inside or outside. However, it is more common to mount the CO2 tank outside of the refrigeration compartment, and there are a few reasons why.
Firstly, having the CO2 tank outside allows for better use of space inside the kegerator. The inside of the kegerator is already limited in space due to the presence of kegs, beer lines, and other components. By placing the CO2 tank outside, you can maximize the available space inside for kegs, making it easier to fit more of them.
Additionally, mounting the CO2 tank outside can also make it more accessible and convenient to refill or replace. If the tank is located inside the kegerator, you would need to open the door and possibly rearrange kegs or other items to access the tank. On the other hand, having the tank mounted outside allows for easy access without having to disturb the contents of the kegerator.
Another advantage of having the CO2 tank outside is that it can help minimize temperature fluctuations inside the kegerator. When the CO2 tank is inside, it can be exposed to the cold air circulating inside the refrigerator, which may cause the pressure to fluctuate. By keeping the tank outside, you can maintain a more consistent pressure level, ensuring a steady flow of carbonation to your kegs.
That being said, there are situations where it may be more practical or necessary to have the CO2 tank inside the kegerator. For example, if you have limited space or if the kegerator is specifically designed to have the tank inside, it can still work perfectly fine. Ultimately, the decision of where to place the CO2 tank depends on your specific needs and preferences.
In my personal experience, I have always preferred to mount the CO2 tank outside of the kegerator. It allows for better organization inside the kegerator and makes it easier to access and refill the tank. However, I have also used kegerators where the tank was inside, and it still worked well. So, it really comes down to personal preference and the specific setup of your kegerator.
