TEED OUTLETS
By "teeing" the water and concentrate outlet lines together a standard beverage (non-post mix) valve can
be used. A single line to the valve allows the concentrate and water to mix before being dispensed. Teed
systems are commonly used with "batch mix" application such as visual units, bubblers and frozen
carbonated beverage. Concentrates that do not blend properly in the line can be improved by installing a
static mixing chamber in line prior to the dispenser.
The single line run lengths should be minimal to reduce backpressure. Backpressure within teed outlet
line should not exceed 32 psi.
[2.0 bar]
. Pre-mix valves with minimal full-flow backpressure are commonly
used with this type of configuration. Teed systems should have a one-way check valve plumbed after the
concentrate outlet and before teeing into the water outlet line to prevent possible water back flow.
Whenever the concentrate is in contact with water the possibility of spoilage is increased and sanitizing of
the system may need to be more frequent.
