Balancing draft beer systems
So far I have been very satisfied with the kegerator I built at the end of last year. It has been performing really well.
I am happy about the fact that the line balancing worked that well. There has been no problems balancing the CO2 pressure in the draft system. It seemed to me like rocket science when I started out, but in the end it was actually quite straightforward as long as I kept track of the various parameters involved. Most of the insights I got from this article. If you are planning on building your own draft beer system I highly recommend the article as it helped me a lot when designing the draft lines in the kegerator.
The fact that the beer line is only 3/16" ID, and relatively long, makes it possible to have quite a bit of pressure in the keg without excessive foaming. There is also about 60 cm of height difference between the center of the kegs and the faucets and this increases the friction in the beer lines and reduces the foaming.
I keep my CO2 regulator at a pressure of 1 bar and there does not seem to be much of a problem adjusting the pressure so that the whole system with four kegs is balanced.

Thats good stuff. I am going to be extending my current keg/tap system to 2 faucets in the near future. I had not thoguht about the load balancing, but that's good stuff to know.
I wonder if I could stick on those faucets, I think I would drink all night and then I will go home to make some tricks on my bed with my wife.
