Recent Events
ERI’s pressure exchangers are market leaders in energy efficiency and durability. These are rotary isobaric devices that transfer pressure energy from the high-pressure reject stream to the low-pressure feed stream, with minimal energy loss.
Models
- PX Q Series: Designed for large-scale SWRO systems, offering the highest efficiency and lowest lifecycle cost.
- PX G Series: Compact and robust, suitable for small to mid-size systems or retrofit installations.
- PX U Series: Built for industrial and wastewater applications with high fouling resistance.
Turbochargers integrate a hydraulic turbine and a centrifugal pump on a common shaft. They use the reject brine energy to boost the feed pressure, reducing energy consumption.
Models
- Turbocharger AT Series: Ideal for medium- to large-sized desalination systems. Available in both cast and fabricated designs.
- Turbocharger LPT Series: Specifically designed for low-pressure brine systems or ZLD applications.
Engineered for performance and longevity, ERI’s pumps are used in tandem with their energy recovery devices to provide consistent flow and pressure for RO systems.
Models
- AquaBold™: High-efficiency axial piston pump with low noise and long service life. Built to work seamlessly with PX devices.
- FlowBooster™: Booster pump optimized for partial-feed and low-pressure systems.
