UNIT WITH INTEGRAL CARBONATOR

NOTE: The unit is factory set to dispense non-carbonated water and carbonated

water as per customer’s requirement. It is available to dispense at most 2

non-carbonated waters ( 6 Flavours ) or 3 non-carbonated waters ( 8 Flavors )

with carbonated water dispensing from the remaining valve(s). Non-carbonated

water dispensing valve(s) may be converted to also dispense carbonated drink(s).

A CO2 cylinder delivers carbon dioxide (CO2) gas through adjustable CO2 regulators

to the applicable syrup tanks or bag-in-box syrup pumps and also the integral (built-in)

carbonator. Plain water enters the integral carbonator carbonated water tank and is

carbonated by CO2 gas pressure also entering the water tank. When dispensing valve is

opened, CO2 gas pressure exerted upon the applicable syrup tank contents or

bag-in-box syrup pump pushes syrup from the syrup supply, through the Unit syrup

cooling coil, and on to the dispensing valve.

Carbonated water is pushed from the integral carbonator carbonated water tank by

CO2 gas head pressure and is pushed through the carbonated water manifold to the

dispensing valve. Syrup and carbonated water meet simultaneously at the

dispensing valve resulting in a carbonated drink being dispensed.

Still (non-carbonated) drink is dispensed in the same manner as the carbonated drink

except plain water is substituted for carbonated water.
