Our reverse osmosis pressure vessels are designed to accommodate all standard seawater RO membrane formats, including 2.5″ × 21″ (2521), 2.5″ × 40″ (2540) and the new, more compact 3.0″ × 21″ (3021) membranes.
They are available in configurations from single-element to multi-element systems, allowing flexible watermaker layouts for a wide range of onboard installations.

This design philosophy results in a cleaner, more compact, and more service-friendly installation, with improved accessibility and a professional layout inside the engine room or technical space.
Especially when combined with 3021 membranes, the shorter vessel length and optimized port sizing allow modern watermakers to achieve high performance while making far better use of available space onboard.

Our RO membrane housings are engineered for reliable marine use, offering an elegant and practical solution for building efficient, compact, and visually clean desalination systems—whether for new installations or upgrades of existing watermakers.
