Reverso Osmosis
Water quality is so varied from location to locations, especially when comparing the west coast to Australia to the east coast that although not necessary for all espresso machine setups, there are some locations that Reverse Osmosis is the only viable solution to provide the best water quality to both protect the espresso equipment and allow for the best possible espresso extraction.
The tailored blending process of the Overture Reverse Osmosis units removes just the right amount of dissolved solids from the incoming tap water to achieve the desired final water quality, and as such system operation is tailored to the water quality at each location. Reverse Osmosis reduces limescale build-up that can cause excessive machine downtime and increased maintenance costs, as well as reducing chlorine taste and odor and other contaminants that can adversely affect the taste of water and resulting espresso.
It is important to note there are horror stories of reverse osmosis systems causing issues to espresso machines, this is due to cheap systems being used without blending capabilities and subpar filters. Everpure are the industry leaders in Reverse Osmosis technology and were the system of choice for the World Barista Championships.
