PREMIX
Premix fountain dispensing consists of a container of
beverage ready for dispensing, beverage delivery
system, carbon dioxide (CO
2
) propellant, beverage
cooling system, and dispenser. We shall discuss each
component of this type of system within the context of
this manual.
The major advantage of a premix system over most
other types is its flexibility. This flexibility is the ability to
go anywhere. Many premix systems will operate
without electric power or separate water supply.
POSTMIX
Postmix fountain dispensing consists of either a tank
(called a Figal) or a box (called a Bag-in-Box) of
beverage syrup. The postmix system will also include
the carbonator, fresh water supply, carbon dioxide
(CO
2
) supply, syrup delivery system, beverage cooling
system, and dispenser. We shall discuss each
component of this type of system within the context of
this manual.
The major advantage of the postmix system over most
other systems is the very low cost of delivering a high
quality, fresh beverage to the consumer utilizing less
floor and storage space for the quantity of beverages
served.
PIPING
The fountain system is connected together by a series
of tubing or hoses. This tubing is called beverage tube
and is commonly available in 1/4" (0.64 cm), 3/8" (0.95
cm), and 1/2" (1.27 cm) inside diameters. Beverage
tubing is a flexible, high-pressure tubing. This tubing is
capable of withstanding system pressures in excess of
100 PSI (6.9 bar). The beverage tubing may be an
individual line or assembled with many lines of tubing
bundled together.
The beverage tubing is attached to the various
components of the system with barbed stems, nuts,
tees, etc. The tubing is held onto the fittings with small
tube clamps called stepless (Oetiker
®
) clamps. When
attaching the tubing and fitting to a “flared” fitting, the
use of a flare washer is required.
