The OceanXTM combines the main high pressure pump and energy recovery pressure exchanger in a single unit and does not require any additional pumps or controls (flow diagram and power model).  In fact, the unit precisely regulates the product flow and recovery of your system and thereby eliminates the need for many of the instruments and controls typically required in reverse osmosis applications. The OceanX was specifically designed for reverse osmosis applications and is the most efficient and simplest pump and energy recovery solution that exists today.
