Balancing the System
DETERMINING RESTRICTOR LINE LENGTH AND
APPLIED KEG PRESSURE
In order to ensure a proper, foam-free, beer flow from
each faucet, the following instructions and calculations
must be completed. Use the formulas found in this
section to determine the required restrictor line length
and applied keg pressure needed for each beer line. In
order to complete these calculations the following
information will be needed:
•
Brands of beer to be dispensed (if blended gas is
used to push the beer, this is not required).
•
Temperature of the Walk-In Cooler (default 38°F
[3.3°C]).
•
Altitude (Distance above sea level).
•
Total line length for each beer line.
•
Overall lift or drop for each beer line.
To determine the appropriate Applied Keg pressures
and Restrictor Line Lengths see attached work sheets
and refer to examples A and B.
To properly determine the required restrictor line
lengths and applied keg pressure to be used for each
beer follow the instructions below.
1. First determine which brands of beer will be
dispensed at which faucet. Use the “System
Calculators” to record data (see the Charts
section).
2. Determine keg temperature at cooler.
3. Once the brand and keg temperature are known
the Internal Keg Pressure can be found by
referring to the “Natural Keg Pressures Chart” in
the Charts section.
4. Determine the number of feet above sea level to
adjust natural keg pressure for particular location.
5. If required adjust for “Lite” or “Light” beer by
adding 1 psi to natural keg pressure. Check with
local beer wholesaler for additional information.
