Dupla RO 200 : a compact reverse osmosis system for pure water every day
The reverse osmosis system Dupla RO 200 produces ultra-pure water for the freshwater aquarium, reef and aquaponics. Delivered ready to use, it combines a sediment filter, an activated carbon filter and a reverse osmosis membrane to retain most of the salts, nitrates, phosphates and pollutants from the mains supply.
Made by Dupla (Germany), this compact model produces 120 to 200 litres of RO water per day, without electricity, using only the mains pressure.
💧 Pure water without electricity
Tap water passes through the three filtration stages : the sediment filter traps particles, the activated carbon removes chlorine and organic pollutants, then the reverse osmosis membrane blocks almost all of the dissolved salts. You get RO water ideal for preparing stable seawater, recreating precise parameters in freshwater or feeding an aquaponic system.
✅ Ready to use and easy to install
The RO 200 is delivered fully assembled, with its membrane, its sediment filter (5 microns) and its carbon filter. It connects simply to a cold water tap : no complex installation or electrical connection is required.
