Rex-Royal S300

The Rex-Royal S300 is a countertop super-automatic coffee machine developed and manufactured in Switzerland, purpose-built for professional operational environments. The machine operates on a bean-to-cup principle with a robust metal brew group and is available in numerous variants distinguished by different combinations of milk, hot water and instant modules. The variants (factory designations) are: CT, CTI, CTH, CTIH, CST, CSTI, MCT, MCTI, MCST, MCSTI, MCT-CF, MCTI-CF — they differ in hot water, milk and instant module configurations. From the coffee-only variant to the full configuration with integrated fresh milk cooling system and CompactFoam technology for variable microfoam, the S300 can be tailored precisely to each location's requirements. The mandatory mains water connection and Ethernet-based cloud connectivity underscore the positioning for fixed installations with high throughput. With dimensions of 342 × 620 × 758 mm (width × depth × height), the machine remains compact enough for counter placement, while weight depending on configuration variant ranges between 43 and 57 kg. Rex-Royal positions the S300 in the enterprise segment, targeting operators who prioritize durable Swiss quality and a modular platform concept.

The Rex-Royal S300 presents itself as a compact countertop super-automatic with clear, straightforward design language. All variants share identical external dimensions of 342 × 620 × 758 mm, which considerably simplifies planning for location changes or configuration upgrades. Weight ranges from 43 to 57 kg depending on variant. The metal brew group is the heart of the machine and processes a generous portion of ground coffee per extraction, which positively affects flavor extraction. Two separate bean hoppers with capacity up to 1.2 kg per hopper (2 grinders) permit simultaneous use of different roasts — for instance a robust espresso blend and a mild filter coffee blend. In instant variants, additional powder compartments for cocoa or milk powder are provided, each with 0.8 kg powder capacity. The entire construction originates from Swiss manufacturing at the Dällikon facility in Canton Zurich, which ensures short supply chains and consistent quality control throughout. Optional accessories such as a cup warmer or transport cart supplement the base configuration and enable flexible adaptation to different installation scenarios.

The central operating element of the S300 is a 10.1 inch touchscreen with video capability, enabling operators to display promotional videos or product imagery directly on the machine. Beverage programming allows numerous freely configurable recipes that can be conveniently adjusted via the display or the Rex-Royal Cloud. The cloud platform establishes a bidirectional connection over Ethernet and provides sales statistics, remote support, remote configuration of beverage recipes and upload of promotional content to the screen. For operators managing multiple locations, this substantially reduces administrative workload because parameter changes can be deployed centrally without requiring an on-site technician. The user interface is intuitively designed and guides end users to their desired beverage in just a few touches. For paid operation, an MDB-compatible interface is available through which standard coin, banknote and cashless payment systems can be integrated. This industry standard widespread in the vending sector ensures broad equipment compatibility and simplifies integration into existing billing systems.

Technically, the S300 relies on a proven metal brew group, durably constructed to deliver consistent extraction results even at high daily throughput. The integrated grinder processes whole beans directly before the brewing process — a quality hallmark expected in professional coffee preparation. The milk system merits particular attention: the product line offers both classic fresh milk modules with integrated cooling and CompactFoam technology, which produces variable microfoam and can process multiple milk varieties simultaneously. This enables preparation of Cappuccino, Latte Macchiato and Flat White in different foam consistencies without manual intervention. Electrical connection is available in several configurations: single-phase variants operate at 380–415 V, 50/60 Hz, while higher-performance models require three-phase connection and accordingly deliver higher heating capacity. Power consumption ranges from 1.9 to 6.4 kW depending on variant. The mains water connection uses a standardized fitting, with the manufacturer providing clear specifications for operating pressure and water hardness. For locations without fixed water supply, an optional tank system is available as an accessory, enabling autonomous operation.

According to distributor specifications, the S300 is designed for daily throughput up to 500 cups; typical sizing depending on settings and product mix frequently aligns with approximately 500 cups per day. Hourly output varies by beverage type: Espresso (40 ml) up to 87 cups/h, coffee (125 ml) up to 81 cups/h, Cappuccino (80 ml) up to 83 cups/h, Latte Macchiato (120 ml) up to 49 cups/h. Two separate bean hoppers with capacity up to 1.2 kg per hopper (2 grinders) and in instant variants additional powder compartments with 0.8 kg powder capacity each provide adequate supplies that can bridge half a workday without refilling under moderate consumption. The grounds drawer accommodates spent coffee grounds and can be removed tool-free; alternatively, direct discharge into an under-counter container is available, further extending emptying intervals. A key argument for professional deployment is the automatic, HACCP-compliant cleaning process covering brew group, milk lines and outlet system. It can run on a scheduled basis, ensuring that food service hygiene requirements are met without manual intervention. This reduces training requirements for operational staff and minimizes the risk of hygiene deviations during daily operation. The hot water function suits tea and instant soups and is available depending on boiler option at performance up to 33 liters per hour.

The Rex-Royal S300 is positioned in the enterprise segment, with documented retail price per distributor at approximately 14,024 € net (Roundstone Vending, 08/2024). The machine targets operators seeking a professional, durable solution and willing to invest in Swiss manufacturing quality. The modular variant structure allows investment to be matched precisely to actual requirements: an operator without need for a fresh milk module can select a lower-cost base variant and retrofit higher-specification configurations as demands increase. On the secondary market, S300 models are traded at considerably lower prices, making the machine interesting for cost-conscious newcomers. Operating costs are positively influenced by the automatic cleaning process and cloud-based remote servicing, as on-site technician visits become less necessary. The mains water connection also eliminates the effort of manual tank filling. Total cost depends heavily on the selected variant, daily beverage volume and local service terms and should be calculated as part of an individual cost-benefit analysis.
