The S121L Gravity combines two flavour sides with a mixed-flavour dispense option. Its intuitive controller includes intelligent fault detection, while the cylinder-heating function is designed to prevent lumpy or icy product. Each side has a separate cooling system. The solid discharge door uses heavy-duty lock nuts, and smooth start-up is intended to reduce noise and energy use.

The machine reaches ready state in approximately 6-8 minutes. Air cooling is standard, with a water-cooled configuration available on request. The controller can optionally be relocated for a self-service bar arrangement. The catalogue mentions a pasteuriser cycle only for the air-pump model, so that feature is not claimed for this Gravity model.

The catalogue lists two 9.5 L capacities and production of two 35 L batches per cycle. It lists the machine weight as 260 kg. Those paired capacity, paired production and unqualified weight values are retained here because the structured registry cannot represent them without changing meaning.
