The use of water-saving devices in coffee machines is becoming increasingly popular in order to prevent high costs and damage to the premises. In fact, the presence of vending machines in public premises, companies, shops, gyms and all public use environments is increasing.
Confida, the Italian Association for Automatic Vending and the European Vending & Coffee Service Association (EVA) provide us with data on significant numbers of coffee and beverage vending machines in Italy and Europe. Here only France and Germany follow our country. We are talking about more than 4 million vending machines, 2.5 million hot beverages dispensed per year at an average of 180 users per machine, with an annual turnover of around 16 billion euros.
Of these, coffee and hot drink vending machines are the majority, predominantly coffee ones. According to the latest Covid-19 pre-pandemic estimates, Italians alone consumed 2.7 billion coffees at vending machines.
Such a turnover, which revolves around a product connected to the water network, exposes our society to an increasing risk of unnecessary water consumption, which is not exclusively functional for the operation of the dispensers.
These coffee and hot drink dispensers can be an aggravating leak risk for two reasons:
- limescale build-up compromises their operation and the regular flow of water in the set nominal volumes;
- mechanical failure, e.g. of connection pipes, can lead to leaks.
Coffee vending machines placed in these public and work spaces cannot be constantly monitored. On closing days, for example, the premises are exposed to the risk of coffee machines malfunctioning. In the event of a breakdown and leakage, they remain in operation, risking:
- damage to the premises;
- wasting water;
- increasing costs in the bill.
It should be emphasised that one of the main causes of coffee machine malfunctioning is the accumulation of limescale, which by depositing itself inside the pipes alters the water transit.
For these reasons, coffee vending machines can be equipped with water-saving devices capable of blocking the flow at the first anomaly.
