Multiplex Company, Inc. Complete System Overview Ingredients Required to Manufacture Quality Carbonated Water Good Quality CO2 Multiplex Refrigeration Units are designed to operate properly on 90 psi (6.4 bar) of CO2 pressure. Clean Water Carbonated drinks are made up of over 83% water. Clean water is required for good taste and to protect the equipment. Cold Temperature Multiplex Refrigeration Units use a cold carbonation system, water is carbonated in an ice cold water bath.
Multiplex Company, Inc. Complete System Overview Multiplex Post-mix Beverage System Multiplex Post-mix beverage systems use filtered water from a filtered water supply system and chill it as it passes through stainless steel cooling coils located in an ice cold water bath. The water bath is maintained at 32°F (0°C) by a mechanical refrigeration system which produces a large ice bank reserve to provide sufficient cooling for peak draw periods.
Multiplex Company, Inc. Complete System Overview Water Filter System Incoming water pressure is to be maintained at 55 psig (3.9 bar) to ensure proper flow throughout the system. An in-line water regulator and gauge controls high water pressure and allows for pressure monitoring. Water enters the pre-filter(s) that remove the coarse particles that are contained in the supply water, protecting the fine filter.
Multiplex Company, Inc. Complete System Overview Carbonation System Carbonator Pump off Carbon dioxide (CO2) regulated to 90 psi (6.3 bar) passes through a single check valve, which prevents water from backing up into the CO2 supply, and fills the carbonator tank with CO2. The incoming filtered water at 55 psig (3.9 bar) feeds the brass carbonator pump, then proceeds through a stainless steel cooling coil located in the 32°F (0°C) water bath.
Multiplex Company, Inc. Complete System Overview Carbonation System (continued) Carbonator Pump on When the carbonated water level in the carbonator tank falls below both the electrodes, the liquid level control will send electricity to the carbonator motor. The motor turns the carbonator pump, which increases the water pressure from 55 psig (3.8 bar) to approximately 140 to 170 psig (10 to 12 bar).
Multiplex Company, Inc.
Multiplex Company, Inc. Complete System Overview Liquid Level Control (Electrode Circuit) (continued) When the carbonator tank is full, carbonated water is touching both the low and high electrodes and the liquid level control will not supply power to the carbonator motor. When carbonated water is drawn out of the tank, it will first fall below the high electrode. This opens the circuit between the G and H terminals of the liquid level control.
Multiplex Company, Inc. Complete System Overview Circulating Carbonated Water Supply System Cold, carbonated water is pushed from the carbonator tank by 90 psig (6.3 bar) of CO2, up through the pick up tube and out of the carbonator tank. It is then chilled as it flows through the stainless steel cooling coil located in the 32°F (0°C) water bath. Feeding a stainless steel circulating pump, the chilled and carbonated water is then forced up to the dispensing station.
