The ECHOTec ECO-Series provides the most advanced and cost-efficient RO solution in this output range. With their field-proven, ultra-reliable, rotary piston energy recovery pump, the ECO system produces 2400 gallons / 9060 Liters of potable freshwater per day from brackish or seawater at an incredibly low cost.

Ultimate energy efficiency for
off-the-grid seawater desalination.

The ECO-Series has been especially designed for self-installation and operation by people without an engineering background. This desalination system comes with a comprehensive installation manual and dedicated support directly from the manufacturer. All systems are also available as a turnkey-ready solution, from the layout to the commissioning of your desalination system. Ideally suited for use with high-cost power supply and for off-grid hotels, farms, waterfront homes, small communities or disaster areas where supplying energy and clean water can be logistically complex and expensive.
The newly engineered open frame design provides a tidy appearance while allowing for easy transport and access to the system’s components for maintenance.
For freshwater capacities of 4800 GPD or 18,140 Liters/day or more, the installation
of multiple redundant operative 2400-ECO-3 modules is the preferred choice. More economical than a single large system, it provides backup, eases transport and installation. During times of low water demand, only the module needed is operated.
