Contactless handwashing station Roller-grill AQUA35

A refrigerated water fountain delivers a continuous flow of chilled drinking water without relying on bottles or tanks. The unit draws water from the mains supply, passes it through a refrigeration cycle, and dispenses it at a steady low temperature. A sealed circuit keeps the water isolated from the surrounding air, preventing airborne contaminants and bacterial growth while maintaining consistent chill levels throughout the day.

The AQUA35 connects directly to the building's cold-water line. Once the supply is turned on, the internal compressor circulates refrigerant through a copper evaporator coil. Water flows across the coil, transferring heat to the refrigerant and emerging at the tap at a temperature suitable for immediate drinking. A small reservoir inside the unit ensures that the next glass is always ready without waiting for the refrigeration cycle to restart.

To use the fountain, the operator simply places a glass beneath the sanitary tap and presses the lever. The tap is designed to project a smooth, controlled jet that minimises splashing and keeps the dispensing area hygienic. A triple-action filter removes sediment, limescale and chlorine before the water reaches the evaporator, protecting both the appliance and the water quality.

The freestanding cabinet is sized to fit against a wall or partition without occupying excessive floor space. The top section houses the refrigeration components, while the lower cabinet provides access for filter changes and routine maintenance. A single power lead plugs into a standard 230 V socket, drawing a modest load that suits most commercial circuits.

The copper evaporator is manufactured to hospital-grade standards, ensuring long-term resistance to corrosion and bacterial colonisation. The refrigeration system uses R290 gas, a refrigerant with low environmental impact. The entire water path remains hermetically sealed, so no air enters the system once it is installed and commissioned.

The 35 L/h output rate matches the demand of busy communal areas, allowing a steady queue of users to fill glasses without delay. The 34 kg weight keeps the unit stable on the floor while still permitting two people to reposition it when necessary. The footprint of 400 mm by 400 mm leaves enough room for the tap and a small drip tray without encroaching on adjacent work surfaces.

Cleaning is limited to the external surfaces and the drip tray. The internal water circuit requires no manual intervention; the triple-action filter is replaced at scheduled intervals following the manufacturer's instructions. The tap lever and surrounding area can be wiped with a sanitising cloth to maintain hygiene between filter changes.

The AQUA35 is supplied with the triple-action filter pre-installed, ready for immediate connection to the mains water supply.
