ROShell Cube RSC.80 (Inside Port)

OVERVIEW

The ROShell Cube RSC.80 series is a high-performance membrane housing engineered for 8-inch reverse osmosis membranes, featuring proprietary InsidePort internal connection technology.

Unlike conventional systems, InsidePort enables direct internal connection between pressure vessels, eliminating the need for external piping manifolds. This results in a cleaner system layout, reduced leak points, and improved hydraulic efficiency.

The integrated saddle system provides structural support without requiring an external steel frame, significantly simplifying installation and reducing overall system footprint.

Manufactured using filament-wound fiberglass reinforced epoxy composite, the RSC.80 delivers high strength, corrosion resistance, and long-term operational reliability in demanding industrial environments.

APPLICATIONS

• Desalination plants
• Industrial reverse osmosis systems
• Modular RO systems
• EPC and OEM water treatment projects

INNOVATION NOTE

InsidePort Technology

InsidePort transforms reverse osmosis system design by moving connections inside the pressure vessels:

• Eliminates external piping manifolds
• Reduces installation complexity
• Improves system reliability
• Enables compact, modular configurations

This approach redefines how RO systems are engineered — from external complexity to internal precision.
