PATENTS

One of the Polti’s keys to success is the development of exclusive technologies which make Polti products reliable and enable them to meet the required laws on safety and consumers’ needs.


THE SAFETY CAP
In 1988 Polti invented the “safety cap” applied to both Vaporella and Vaporetto, patented world-wide. The cap will not open if there is even the tiniest bit of steam pressure in the boiler, preventing accidental opening and injury.		   SANI SYSTEM
The nozzle of Polti Sani System has a patented system consisting of a controlled-expansion heat-exchanging device that heats the steam further, bringing it to a temperature of 180°C.

  CREMA EXPRESS
Patent present on all Polti espresso machines. This device forces the water to stay in the capsule for a few seconds, thoroughly impregnating the coffee. This ensures a natural pre-infusion allowing complete use of all the coffee’s aroma. Sufficient pressure and a micro-injection of air while coffee is being dispensed creates thick, long-lasting cream.
