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.

How Does an Energy Recovery Device Work?
At ECHOTec Watermakers, our 2400-gallon per day (GPD) desalination device operates on the remarkable principle of reverse osmosis. This process involves pushing seawater through a semi-permeable membrane, effectively removing salts and impurities and leaving behind crystal-clear, potable water. Think of it as nature’s filtration system being mimicked and enhanced by cutting-edge technology.
Our 2400 GPD device is equipped with state-of-the-art energy recovery devices (ERDs), which play a pivotal role in maximizing the system’s efficiency. ERDs capture and reuse the energy expelled during the desalination process, significantly reducing the overall energy input required for freshwater production. This innovative approach ensures that every drop of water is produced with minimal environmental impact.
Imagine the efficiency boost provided by recycling the energy that would otherwise go to waste. The ERD essentially acts as a virtuous cycle, making the desalination process not only more sustainable but also more cost-effective in the long run.
How Much Energy Does Reverse Osmosis Desalination Use?
The answer to this question depends on what kind of machine you choose to purchase. The 2400 GPD device stands as a testament to this advancement, utilizing energy in a manner that sets it apart from its traditional counterparts. By employing cutting-edge design and technology, our system achieves a substantial reduction in energy consumption, making it a more environmentally friendly and cost-effective solution. The specifics of this device can be seen above in the graphic.
Why Is Reverse Osmosis Better Than Thermal Desalination?
In the realm of desalination, two primary methodologies dominate the landscape – reverse osmosis (RO) and thermal desalination. Reverse osmosis, the method employed by ECHOTec Watermakers, involves pushing seawater through a semi-permeable membrane, separating salts and impurities to produce fresh water. On the other hand, thermal desalination relies on the evaporation of seawater, followed by condensation to collect purified water.
While both methods share the goal of converting seawater into potable water, they diverge significantly in terms of efficiency, cost-effectiveness, and environmental impact. Reverse osmosis is hailed for its superior efficiency compared to thermal desalination. The 2400 GPD device by ECHOTec exemplifies this efficiency, utilizing energy recovery devices and advanced membrane technology to minimize energy input. In contrast, thermal desalination methods, such as multi-effect distillation or multi-stage flash, often require higher energy inputs due to the need for extensive heating and cooling processes. A sailboat desalination system/home desalination system that uses a reverse osmosis system, like the 2400 GDP system, is the best option for people interested in living off the grid.
How Do You Purify Water Off the Grid?
Off-grid locations, whether remote communities, expeditionary settings, or maritime environments, face significant challenges in obtaining clean and reliable water sources. Traditional water infrastructure is often absent, leaving residents, explorers, and sailors reliant on natural sources that may be contaminated or insufficient for their needs. Common challenges include microbial contamination, high salinity in water sources, and the lack of access to municipal water treatment facilities. These factors contribute to a critical need for innovative, off-grid water purification solutions.
ECHOTec Watermakers understands the unique challenges of off-grid water purification and has developed cutting-edge solutions to address these concerns. Our off-grid water purification systems, exemplified by the 2400 GPD device, are designed to provide the best off-the-grid desalination systems.
Off-grid locations often lack access to a stable power grid. ECHOTec Watermakers has addressed this challenge by designing systems that can operate using a variety of power sources. This is seen in our solar panel desalination systems.
