Description Spec Sheet / Manual
 
HP-HEMI Turbocharger
The HEMI is a motor assisted HPB. The HEMI provides control of feed and brine flows in SWRO while the primary feed pump runs at constant speed and pressure.

What the HEMI does:
  • Provides exceptional energy recovery efficiency
  • Eliminates the VFD on the High-Pressure Pump
  • Computational Fluid Dynamics analysis optimizes every HP-HEMI for peak efficiency at your duty point conditions
  • Industry-leading three (3) year limited warranty
  • Super Duplex SS 2507 standard MOC
  • Complete ERD package – user provides just standard control signals, power, and process piping

Why the HEMI?
  • Lowest CAPEX of any ERD
  • Lowest Specific Energy Consumption
  • Highest Reliability
  • No compromises on membrane operating

How FEDCO Turbochargers Work
FEDCO’s Hydraulic Pressure Boosters or HPB energy recovery turbocharger leads the industry in efficiency and reliability. The HPB™ turbocharger reduces the energy consumed in a seawater RO system by up to 50%. With the HPB™, you can recover more than 80% of the wasted high pressure brine energy to reduce the size of the high pressure feed pump, lowering the motor electrical consumption. In the turbocharger, the high pressure concentrate or brine stream from the membranes enters the turbine side of the unit. This high pressure flow spins the turbine impeller of the rotor. The rotor converts the hydraulic energy into mechanical energy used by the pump side impeller. This mechanical energy provides a pressure boost to the feed stream. This boost reduces the pressure requirement of the RO system high pressure feed pump. The one piece custom engineered rotor feature the patented RotorFlo™ technology that eliminates external lubrication lines ensuring maximum reliability and minimal maintenance.

HP-HEMI
The HP-HEMI models cover the largest current and anticipated SWRO trains. Standard MOC is Super Duplex SS 2507. Brine nozzle valve actuators, flanged connections and other options available. FEDCO provides the complete HEMI package including motor, VFD and valve actuator.

  1. Brine aux nozzle actuator
  2. HEMI motor
  3. Brine discharge module
  4. Common baseplate
