RO Seawater Desalination Systems for Yachts and Superyachts

Designed to reliably endure extreme marine conditions, far from factory-trained service centers, the ECHOTec PRO-Series provides small to medium sized commercial vessels and larger yachts with a dependable source of high quality potable water.
Simple self-installation, if requiredand minimal maintenance effort and operators’ input are the key features of these field proven watermakers.

Because only track records count, ECHOTec PRO-Series desalination systems are built without finicky electronics or touch screens.
Despite the multitude of standard and optional system features such as real time salinity monitor, hour meter, low/high pressure safety shut off, fresh water flush and failsafe product diverter, all functions are controlled by rugged mechanical components and low voltage electrical circuitry – more reliable and field repairable wherever you go. For freshwater capacities of more than 7,000 GPD / 26,495 Liters, the installation of any number of redundant operative BHL desalination modules provides unlimited output. More economical than a single large system, multiple desalination modules provide back up, ease transport as well as installation and reduce the electrical start up load by more than 40%. In times of low water demand, only the modules needed are operated for lowest maintenance effort and ultimate cost efficiency. Upgrades are easy, fast and available in 1,800 GPD and 7,000 GPD increments.
The newly engineered marine aluminum frame provides tidy appearance while allowing easy access to the system components for maintenance. The semi-modular bulkhead mount systems or the self-contained vertical framed systems are space saving and almost turnkey, so that people without engineering background can install them.
