Back 21

system designed to separate nitrogen from compressed air typically by membrane; nitrogen used for beer dispense in a mixed gas application must be >99% pure

Front 22

Front 25

PSI

Back 25

pounds per square inch

Front 26

Regulator

Back 26

gas control valve that delivers set pressure to keg; primary regulator is used for gas to keg (CO2 & N2) while secondary is used to push gas through keg to the faucet

Front 27

Resistance

Back 27

a measure of the pressure drop across a component or over a length of tubing at the optimum beer flow rate

Front 28

Sankey

Back 28

refers to the modern style of keg coupler

Front 29

Series Keg

Back 29

hooking multiple kegs together so the beer flow from the first flow through the second and then into the next so that the kegs can be changes less frequently

Front 30

Shank

Back 30

connection piece that foes through the cold box wall or tower and connects tubing/tailpiece to tap

Front 31

Short Draw

Back 31

draft system under 50ft long; can be run on straight CO2 or mixed gas (later preferred) with air-cooled or refrigerated lines

Front 32

Tail Pieces

Back 32

connectors that allow a piece of tubing to be attached to a piece of equipment

Front 33

Tap

Back 33

connector from the draft system to the keg

Front 34

Tower

Back 34

the mount on the bar that holds the faucets and is cooled to maintain beer temperature up to point of dispense

Front 38

Clear Vinyl

Back 38

used for beer lines in direct draw systems; easily replaceable

Front 39

Colored/Branded Vinyl

Back 39

used for CO2 gas

Front 40

Stainless Steel

Back 40

tubing in jockey boxes

Front 41

Barrier Tubing

Back 41

low resistance beer lines in long draw systems

Front 42

Polyethylene

Back 42

used to carry glycol coolant

Front 43

Temporary

Picnic pump, jockey box or cold plate

Back 43

used for one-day events to dispense beer that’s been iced down to prevent from heating up; pump pushes air into keg which oxidizes beer; both jockey box & cold plate have difficulty maintaining constant temp

Front 44

Direct Draw

Kegerator or walk-in cooler w/ dispensing unit directly connected

Back 44

short jumper connection from keg to faucet; direct C02 contact which will oxidize beer quicker; beer is kept at constant temperature unlike temporary systems

Performing Proper Draught Maintenance
Perform Line Cleaning Every Two Weeks

Back 46

1) Push Beer from lines w/ cold water
2) Clean lines w/ caustic solution @ 2% or greater concentration for newer, well maintained lines or 3% for older or problematic lines; maintain solution of 80-125 F
3) Caustic solution should be circulated through the lines for 15 mins at the velocity of 2 gal/min for electric pump cleaning or left to stand in the lines for no less than 20 mins for static cleaning
4) Disassemble and hand clean faucets; hand clean couplers
5) After cleaning, flush lines with cold water until pH matches that of tap water and no visible debris is being carried from line

Front 47

Performing Proper Draught Maintenance
Perform Line Cleaning Every Quarter

Back 47

1) Disassemble and hand clean all FOB-stop devices (aka beer-savers, foam detectors)
2) Disassemble and hand clean all couplers
3) Perform acid cleaning of draught lines as follows:
- Push beer or caustic cleaner from lines with cold water
- Clean lines with an acid line cleaner mixed to manufacturer's guidelines; maintain a solution temp of 80-125 F
- Circulate the acid solution through the lines for 15 mins at a velocity of 2 gal/min for electric pump cleaning or let stand in the lines for no less than 20 mins for static cleaning
- After acid cleaning, flush lines with cold water until pH matches that of tap water and no visible debris is being carried from the lines

Serving Proper Draught Beer

Back 49

1) Stored between 34-38 F
2) Served between 38-44 F
3) Glycol cooling used in long draw system set between 27-32 F
4) Balanced draught settings
5) Normal flow rate of 2oz per second

Front 50

Pressure v. Temperature

Back 50

1) beer carbonation responds to changes in storage & serving conditions
2) beer temperature and the CO2 pressure applied through the coupler:
- influence the amount of CO2 dissolved in any keg of beer
3) at any temperature, a specific pressure must be applied to keg to maintain the carbonation established by the brewery
4) if temperature or pressure varies, carbonation levels will change
5) temperature goes up, increase pressure; temperature goes down, decrease pressure
