Contactless handwashing station Roller-grill AQUA30

A refrigerated water fountain supplies chilled drinking water continuously by drawing from the mains supply and cooling it through a sealed refrigeration circuit. The system removes heat from the water as it passes over a cold evaporator, lowering its temperature without exposing it to air, which prevents bacterial growth and keeps the water fresh. The cooled water is then dispensed through a protected tap, ready for immediate consumption without the need for bottles or manual refilling.

The AQUA30 from Roller-grill is a freestanding unit that connects directly to the building's water supply. Once installed, the operator turns on the power and the fountain begins cooling the incoming water to a consistent low temperature. Users press the tap to fill glasses or bottles with chilled water, and the unit maintains the set temperature automatically, requiring no further adjustment during service.

Built as a floor-standing model, the AQUA30 has a compact footprint that fits against a wall or in a corner. The outer casing is designed for public environments, with a sturdy construction that resists knocks and spills. Inside, the refrigeration circuit uses R290 gas, a refrigerant chosen for its low environmental impact and efficient cooling properties. The evaporator is made of copper, a material selected for its natural antimicrobial properties and compliance with hospital-grade hygiene standards. The water circuit remains completely sealed, ensuring no contact with airborne contaminants.

Controls are minimal: a single power switch starts the cooling cycle. The tap itself is designed with a protective guard to prevent accidental contact, meeting sanitary requirements for direct consumption. An optional triple-action filter can be added to remove sediment, limescale and chlorine, though this is not included as standard.

With a power rating of 0.28 kW, the unit draws a modest load suitable for standard 230 V circuits found in offices, canteens and public buildings. Its weight of 34 kg allows it to be moved by two people and positioned without specialist equipment. The dimensions of 300 mm wide, 340 mm deep and 1010 mm high create a slim profile that occupies minimal floor space while still providing a 30-litre-per-hour output, sufficient for steady demand in busy environments.

Cleaning is straightforward: the tap and surrounding surfaces can be wiped down with a disinfectant, and the sealed water circuit requires no internal maintenance beyond occasional checks of the optional filter if fitted. The unit is designed for continuous use in public spaces, with materials and construction that withstand frequent operation and easy access for routine upkeep.

The AQUA30 is categorised as a refrigerated water fountain for public and communal settings, offering a mains-fed alternative to bottled water dispensers.
