The “Punto Acqua” water distribution point is a two-metre tall hexagonal kiosk equipped with three taps: one for still water, one for chilled still water and one for chilled sparkling water.
Cleanliness and hygiene of the water distributed by “Punto Acqua” is guaranteed by UV sterilizer installed at the taps. Food-grade liquid carbon dioxide is used and is stored in a separate tank. Sparkling water is carbonated by a saturator immersed in the water. The carbon dioxide quantity varies from 5 to 10 grams per litre.
A refrigerating circuit chills the water. The average deliverable chilled water is 180 litres per hour. Units from 0.2 litres to 1.5 litres are obtainable. The delivered volume is set by a microprocessor.
Still water - at room temperature or chilled - is free. 1.5 litres of sparkling, refrigerated water costs 5 cents. The distributor is provided with a token machine which accepts various coins. Timetable operation of the “Punto Acqua” water distribution point is programmable.
