That's a great resource but raised another question. I have read many people keep the Co2 tank in the kegerator but this guide states that should not be done with no reason listed as to why? So why is this not recommended? Mine is inside, does it really matter?
Because you can fit more kegs in the kegerator if you don't store the co2 bottle in it . At least that's my reason!
Yea, I get that but in my case it would only allow me a 3 gallon keg so not really a big deal, the article though made it seem like it was a bad idea to keep it inside as in detrimental but no reason why was provided so I am curious.
I think there is a bit of science and a bit of experience at work. The ideal gas law, PV=nRT, states that as temperature goes down (T), then the pressure (P) of the system (the CO2 tank) also must go down assuming volume (V) and amount of gas (n) are kept constant. That's the first item.
The second item is experience. I have heard people express concern about tank and regulator seals not working as well at lower temperatures, problems with freezing due to rapid dispensing and keg space being used by the tank.
I keep my tank in the refrigerator and have no complaints. I think you can do whatever works best for you and your system/set-up.
