BWT PERMAQ® Pro Duo 250 - 1000 Product data sheet 09/2014 Double-pass reverse osmosis system Bacteria-free and clean water for demanding requirements Benefits:  Ultra-clean water in accordance with DS/EN 285  Water quality <5 µS/cm w/NaOH dosage  Retains microorganisms such as bacteria and pyrogens  Flow meter for direct reading of permeate and concentrate capacity  If there is no water supply (low inlet pressure) the system switches off automatically  High capacity per membrane  Conductivity meter fitted with the option of an alarm  Dosage of lye (NaOH) between 1 and 2 pass to bind the released CO2, whereby the water quality nd after the 2 pass improves st nd Bacteria-free and safe water quality Features: Letting the water pass through a single membrane already creates good water quality. Unlike a conventional reverse osmosis system, the DUO series takes the filtered water through another membrane nd filtration (2 pass) to remove even more of the few remaining salts in the water.  Ultra clean water using double-pass reverse osmosis  Automatic stop of the system, if the inlet pressure is too low This process creates extraordinarily clean water, which meets the specifications for water in DS/EN 282 – water for sterilisation, steam autoclaves, large autoclaves, etc.  Hospitals, laboratories and sterilisation centres Typical application areas:  Autoclaves  Evaporators  Chemical industry  Laboratories  Humidifiers  Process water BWT HOH A/S Geminivej 24 • DK-2670 Greve Tel.: +45 43 600 500 bwt@bwt.dk • www.bwt.dk Der tages forbehold for trykfejl og tekniske ændringer.
