Hydranautics SanRO HS-4 Heat Sanitizable RO Membrane

The Hydranautics SanRO HS-4 is a premium Heat Sanitizable Reverse Osmosis element designed specifically for pharmaceutical and high-purity water applications. Engineered to meet the rigorous standards of the medical and biotech industries, this 4-inch element is capable of withstanding periodic hot water sanitization at temperatures up to 85°C (185°F). This capability eliminates the need for harsh chemical disinfectants, ensuring compliance with USP (United States Pharmacopeia) water standards for purified water and Water for Injection (WFI).

This membrane features a specialized "Full-Fit" or "Net-Wrap" outer configuration (controlled by the specific ending code, but standard for the HS series) to eliminate dead flow areas where bacteria could colonize. Constructed with a robust composite polyamide material, the SanRO HS-4 maintains exceptional structural integrity and high salt rejection even after repeated thermal cycling. It is the industry standard for systems requiring absolute biological control and high-grade permeate quality.
