Universal
Universal carbonated water machines include soda dispensers intended for fast-food beverage service. The listed Delta-2 and Delta-4 models show this group is organized around dispenser configurations rather than a single drink format. These units belong where carbonated water is served as part of a beverage station, such as quick-service counters and other foodservice points.
When comparing options, review the model designation and dispenser configuration, then match the unit to the number of dispensing positions or service needs indicated in its product details. Also consider how the machine will fit into the planned beverage workflow, including placement at the counter and access for routine operation. Product-specific documentation should guide final selection.
