LWM Series

Description

The Little Wonder Modular Series Watermaker is ideal for the experienced sailor. Reverse osmosis desalination systems are the preferred choice for boaters who require small low-power watermakers. The systems are simple to install and easy to operate. Perfect for applications where space and power are limited. The quality components that go into these units ensure safety and years of reliable service. Featuring a modular configuration that is also compact, this desalinator is the most reliable, field serviceable, quiet, efficient, and economical source of freshwater available.

Able to produce between 550 – 681 LPD, the Little Wonder is designed for cruising sailboats where space and power are limited and reliability is required

Technology:
• Adjustable 316 SS Pressure Regulating Valve provides constant pressure. No fluctuating pressure and low noise
• Easy to operate High-Pressure Bypass Valve controls the operating mode from cleaning/rinse to reverse osmosis
• High saltwater rejection rate
• Product Sample Valve included
• CIP system allows membrane cleaning/pickling by simple to use cartridges
• Optional remote instrument panel configuration for LWM units

Meters/Monitors:
