How the Multiplex Works

The Model 11M is a 1/2 HP refrigeration unit that will provide premix carbonated beverages and chilled carbonated water for up to 12 gal (45 L) of syrup/day or 560 drinks/day (4,000 gal/year) with a 100 ft (30 m) maximum conduit length. This is a remote refrigeration unit that derives its peak draw capacity from the reserve ice bank produced from a capillary tube refrigeration system. This system is controlled to cycle ON and OFF by the operation of the ice bank control. The sensing bulb that controls the ice bank is located on an adjustable bracket in the water bath.

WATER BATH ACCESS

Has a round hole in the front and back panels with no edge trim to protect lines.

End panel has two ovals in the rear of the panel with edge trim to help protect conduit lines.

SERVICE ACCESS

Front panel was solid and did not allow easy access for service.

Switch panel was mounted flush to end panel.

Sequence of Operation

PRE-MIX REFRIGERATION UNIT

Ice Bank Is Required

1.Check water bath for full ice bank.

2.The stabilized water bath operating temperature must be maintained at 33°F (0.6°C) to 35°F (1.7°C).

The following is a sequence of operations for the Multiplex Pre-mix Beverage equipment.

1.Once a drink is dispensed, the following will occur:

A.For a Syrup Tank System, the Pre-mix syrup is manually mixed at the store. Pre-mix beverage is then transferred to a holding tank for supply to the Multiplex system.

B.For a Bag-In-Box System, pre-mix syrup is drawn from a Bag-In-Box by means of a gas driven syrup pump.

2.The brix pump mixes a 5:1 ratio pre-mixer syrup and water into a 3 gallon holding tank located in the pump box (the 3 gallon tank is vented to atmosphere).

3.The carbonator pump (stainless) pulls the 5:1 pre-mix out of the 3 gallon holding tank and injects it into the pre-mix carbonator tank where the CO2 pressure is 35 psi (2.4 bar) on the tank.

4.The circulator pump runs continuously and circulates water bath water through the conduit to provide cooling for all drinks.
