Protegra OF 750 reverse osmosis system

The Protegra reverse osmosis systems as open frame version (OF), cost effectively produce larger volumes of desalinated water.
The deionization rate is at least 98 %. Additional equipment, such as different tank sizes and pressure pumps, can be added to the plant according to customers’ individual needs. The system can, for instance, be set up as a central water treatment plant with in a building and supplemented with accessories to form a closed circuit pipeline. All systems are equipped with an RS 232 interface.
