Gemini Reverse Osmosis Systems represent a leap forward in both RO miniaturization and membrane technology. The Gemini RO System is a low pressure, fast production, three or four stage RO system, designed specifically for small business, water coolers, and homes. Gemini is capable of producing one gallon of RO product water every twelve minutes (140 GPD). Yet it is compact enough to sit inside a standard water cooler, and smaller than most residential RO systems. The simple mix and match design allows for a variety of system designs to fit your market place and local water characteristics. In areas where bacteria is a concern, SWT offers an optional stainless steel ultraviolet purifier.
