SanRO HS-8 Hydranautics Nitto 8,800 GPD at 225 PSI 8 x 40 inch 99.7% Rejection Heat Sanitizable Full Fit Membranes

Hydranautics SanRO HS-8 Heat Sanitizable RO Membrane

The Hydranautics (Nitto) SanRO HS-8 is a high-performance, specialty reverse osmosis (RO) membrane engineered specifically for high-purity water systems requiring frequent thermal sanitization. Manufactured utilizing a robust composite polyamide polymer, this 8-inch by 40-inch spiral-wound element is a high-rejection, heat-sanitizable membrane designed to deliver exceptional water purity while maintaining strict sanitary conditions. It is fully USP (United States Pharmacopeia) compliant and conforms to FDA Regulation CFR Title 21, making it an industry-standard component for producing purified water in pharmaceutical, medical, biotechnology, food and beverage, and semiconductor manufacturing processes.

Designed to eliminate microbial growth and simplify maintenance, the SanRO HS-8 features a sanitary, full-fit net-type outer wrapping that prevents the "dead flow" areas commonly associated with traditional fiberglass-wrapped elements. This design allows for highly effective cleaning-in-place (CIP) and heat sanitization at temperatures up to 185°F (85°C) without relying on harsh chemical agents. Operating at a standard test pressure of 225 PSI, this membrane produces a highly reliable nominal permeate flow of 8,800 gallons per day (GPD) with a nominal salt rejection of 99.7%. By combining factory heat-setting for predictable startup performance with superior dissolved solids rejection, this RO element delivers the reliable, continuous-duty operation required for critical ultrapure liquid handling.
