The S121T Gravity uses two separate cooling systems so each flavour side is cooled independently while the centre dispense provides the mixed-flavour option. An intuitive controller includes intelligent fault detection, and the cylinder-heating function is designed to prevent lumpy or icy product. A pasteuriser cycle supports the operating workflow, while the solid discharge door is secured with heavy-duty lock nuts.

Smooth start-up is intended to reduce noise and energy use, and the machine reaches ready state in approximately 6-8 minutes. Air cooling is standard; a water-cooled configuration is available on request.

The catalogue lists two 9.5 L capacities and production of two 35 L batches per cycle. It lists the machine weight as 250 kg. These catalogue values are retained here because the current structured field registry does not represent paired capacity, paired per-cycle production or an unqualified machine-weight value without changing their meaning.
