- APRO 100 Pro - Reverse Osmosis€1,263.00 €1,010.40
An APRO 100 PRO is a reverse osmosis system that has been specially developed to be connected to a professional coffee setup.
APRO 100 PRO carefully removes all the impurities that affect the taste of a coffee or espresso. At the same time, the system leaves the necessary minerals that are essential to achieve a rich coffee taste, refreshing tea or just clean water.
The mineralization is easy to adjust and runs completely stably. This is easily done on the knob on the front of the system.
Advantages of APRO 100 PRO:

- Adjustable mineralization via bypass
- Stable taste
- Compact design
- Easy maintenance

-
No scale buildup in your machine
-
No off-tastes from chlorine or contamination
-
Consistent water quality regardless of local source

Maximum flavor and aroma in every cup
