Last year I attended the Micromatic Draft Beer Dispense program and was told that keeping your CO2 tank inside the chiller box would yield 30% less product due to the tank & gas being cold. Keep the tank outside the box was the message. I don't see how this is possible as the CO2 is a liquid that boils off gas as the pressure is lowered--temperature having very little to do with it. Lower temperatures just means that there is more (very little more, BTW) CO2 left in the tank when it's "finished" than there would be at a higher temperature. Bring that same "empty" tank out of the box and warm it up and you'll push another 10 beers. No big deal, and certainly not anything like 30% less. Can someone explain to me their logic?
On a related topic, and one I'm less sure about: We fill our small CO2 cylinders from large ones. The large 50 pounders have a "syphon tube" that extends to the liquid in the bottom of the tank. Past practice (don't know where this came from) has been to chill the small receiver tanks before filling from the larger one. Something about getting more CO2 into the tank. Does this make sense? Thanks for any help!
