Still and sparkling water for restaurants: how it is sized on covers at peak service, how long a CO2 cylinder lasts, and what rental includes.
With WAHU! you bring still and sparkling microfiltered water to the table, bottled directly in your restaurant. An elegant service with customisable glass bottles, more predictable water costs and no more crates of water to order, store and dispose of.

A weekly average is of no use. What decides the machine is the busiest service: Saturday night, a bank-holiday lunch, a large party. If it copes with that, it copes with everything else.
| What we look at | Why it changes the machine |
|---|---|
| Covers at peak service | Our on-counter solutions are sized for up to 200 covers at around 150 litres an hour of cooling capacity. Below that you can go down a size; above it, you plan for more than one point. |
| Filling speed | In service you do not wait: on the automatic versions two litres come out in about a dozen seconds, with a settable dose, so whoever is filling does not have to watch the bottle. |
| Continuous chilling | At the height of service chilled water has to be there: a machine that chills in batches stops exactly when you need it. |
| Where the unit sits | On the counter or the pass, or under the counter with only the tower in sight: in that case the unit can sit up to twenty metres from the dispensing point, and the counter stays clear. |
| Service bottles | With tap filling you prepare the bottles for the dining room, still and sparkling, with no empties to store and return. |
Everyone asks the same question: how often the cylinder is changed. It depends on how much sparkling water you serve, and the yields are these:
| Cylinder | Sparkling water dispensed |
|---|---|
| 1.3 kg | about 260 litres |
| 2 kg | about 400 litres |
| 4 kg | about 800 litres |
| 10 kg | about 2,000 litres |
An example to get a feel for it, with the assumptions stated: 60 covers a day and half a litre of sparkling water per cover make 30 litres a day; with a 10 kg cylinder you are looking at about two months. Your numbers will differ: we redo the calculation on yours.
CO₂ refills are not included in the rental fee and are supplied separately. What rental includes · The solutions for restaurants compared →
Professional high-capacity WAHU! systems, available for sale or rental, to serve always-fresh water even during the busiest moments. Filtration at 0.5 micron (microfiltration) or 0.15 micron (ultrafiltration) depending on your needs. Design, installation and maintenance handled by Gruppo IM Maioli Impianti, supporting local businesses for over 50 years.
The machine stays ours. The fee includes installation, scheduled maintenance at the agreed frequency, sanitization of the system at every visit and restoring operation if it stops.
CO₂ refills and spare parts other than the filtration system are separate; adaptations to the plumbing beyond the basic connection are excluded. For seasonal businesses there is a shorter-term option.
The system is yours, with a 24-month warranty on components. Glass parts and removable accessories are excluded, and for warranty work at your premises labour and travel are charged to the customer.
Scheduled maintenance — visit, sanitization and filter change — is agreed with a dedicated contract.
