BALANCING THE SYSTEM
To keep the proper amount of carbon dioxide gas in
solution in the beer to maintain the proper taste
throughout the life of the keg, the system must have
the proper balance of temperature, applied pressure to
the keg and rate of flow at the faucet.
The installer must calculate, taking into consideration
the static resistance in the conduit (amount of vertical
rise and fall) as well as frictional resistance (the length
of the conduit itself), the internal pressure of the keg
according to the Brewmaster, the altitude at the
location as well as the temperature of the beer in the
cooler. The object is to dispense the beer as fast as
possible (2 oz per second) with the proper gas
pressure (CO
2
or mixed gas) applied to the keg and
adjusted so it will not change the carbonation or taste
of the beer. The installer must determine the proper
pressure applied to the keg as well as the length of the
restrictor attached to the dispensing faucet giving a
consistent properly dispensed beer.
