Isobaric or “positive displacement” energy recovery devices (ERD)s such as PX Pressure Exchanger™ (PX™) devices are the most efficient solution for membrane desalination today. ERI PX devices operate at up to 98 percent efficiency and reduce the energy consumption of seawater reverse osmosis (SWRO) systems by up to 60 percent, making desalination a cost-effective solution for clean water supply.

ERI’s turbine-based devices are designed and built to reduce energy consumption, primarily in seawater and brackish water applications. The ERI TurboCharger energy recovery devices are all custom-designed to reduce energy consumption and increase system efficiency. Much like ERI’s line of PX™ energy recovery devices, these products are simple to operate, durable, require a small installation footprint and are ideal for energy saving applications.

Designed for reliability and optimum efficiency, ERI TurboCharger energy recovery devices offer substantial savings, especially where power costs are lower. Its custom designed hydraulics and 3D geometry allow for optimized performance as compared to competing centrifugal technologies.
