Voltea's CapDI Chosen to Purify Water at CoffeeHouse

VOLTEA’S CAPDI FOR HIGH-QUALITY BEVERAGES Voltea launched their first ever point-of-use CapDI water purification system in late 2017 specifically for the Hotel/Restaurant/Café (HoReCa) industry. Since then, numerous DiUse Systems have been commissioned in the industry, purifying water all over the world to allow for the best cup of coffee, every pour.

Voltea’s DiUse System operates with zero salt required and does so at a higher efficiency with little to no maintenance demands compared to conventional desalination technologies. The technology inside Voltea’s DiUse System, CapDI, is tunable, which is a special feature that no other desal technology provides. With conventional water treatment systems like reverse osmosis (RO), in many cases, most salts and minerals are completely removed only for the beneficial minerals to be added back in via remineralization. The use of Voltea’s CapDI technology eliminates this additional remineralization step, allowing for a more efficient process without the addition of soft salts as with water softeners.

The tunability feature of CapDI allows the customer to decide their mineral and salt removal level based on their application and needs. CapDI then automatically adjusts based on natural variations in incoming feed water salinity to ensure customers get a stable and consistent purified water quality.


According to the Specialty Coffee Association, general and carbonate hardness levels in water can greatly impact the flavor of brewed coffee. The adjacent graph provides a range of mineral levels where coffee is known to have the best flavor, called the “Ideal Brew Zone”. 1 Since over 98% of coffee is actually water, professional baristas and coffee aficionados around the world are familiar with these standards and recognize how important water quality is to produce the very best coffee beverages.
