Product Description
Marine Watermaker – Reliable Freshwater Production for Marine Applications
The SHARK CAPTAIN Marine Watermaker is designed to provide an efficient and reliable freshwater supply for yachts, fishing vessels, commercial boats, and other marine applications. Using reverse osmosis (RO) membrane technology, this system converts seawater and brackish water into freshwater, reducing dependence on onboard freshwater storage and shore-based water supplies.
Available in 80 L/h (WM2000A) and 140 L/h (WM3000A) models, the Marine Watermaker features a compact, split-system design for flexible installation in limited onboard spaces. Equipped with a 316L stainless steel high-pressure pump and high-performance RO membranes, it delivers a salt rejection rate of 99.5% and product water quality of less than 500 ppm under specified operating conditions.
Designed for demanding marine environments, the system offers reliable operation, efficient desalination, and convenient access to freshwater during extended voyages.
