RO Seawater Desalination Systems
for Superyachts and Commercial Vessels 
The ECHO Tec. PRO series is designed for ultimate reliability and easy operation. It supplies small to medium sized commercial vessels and larger yachts with 20 to 60 gallons (75 to 227 liters) per hour - up to 1,500 gal./day (5,600 l./day) of high quality potable water.
The semi modular bulkhead mount system or the self-contained vertical framed system with a footprint of only 27.5 in. x 18 in. are space saving and easy to install.
