3.7  Advantages of the Energy recovery system 

Introduction 

Thank you for choosing a Schenker Watermaker.  
As all the equipment, the knowledge of operating and maintenance procedures allows to use the system in the 
best  way,  and  to  guarantee  a  perfect  functioning  throughout the  years. We  invite  you  to read  carefully  this 
manual and to keep it for a quick reference. 
 

Functioning principles 

The  Schenker  watermakers,  as  alternative  to  the  high-pressure  pumps  of  traditional  systems,  utilizes  the 
ENERGY  RECOVERY  SYSTEM  patented  device,  which  amplifies  the  pressure  of  common  low-pressure 
pumps, and recoup all the hydraulic energy back from the membranes, allowing an high energy efficiency. 
The lack of high-pressure  pumps makes the system silent and vibrations free, and enormously simplify the 
use because no adjustment is necessary for its operating.
