Bag in box soda connects directly to your soda fountain lines to dispense carbonated beverages. It can easily be swapped out with a new box to refresh your soda supply or to add a different flavor. They use carbon dioxide to push syrup out of the bag to mix with carbonated water. This mixture of carbonated water and syrup flows through the dispenser into a cup, ready for customers to enjoy. Bag in box systems portion out and mix ingredients, making it an easy method for employees to rely on.
