Hydranautics SanRO HS2-8 Membrane

Product Description

SanRO membranes from Hydranautics provide reliable, sanitary membrane performance in USP Classified water systems. SanRO’s unique design eliminates “dead flow” areas - potential breeding grounds for bacterial growth - and ensures maximum ion removal with minimal fouling. SanRO-HS, and the new SanRO-HS2, provide all the benefits of SanRO in a heatsanitizable membrane, designed for sanitizing at 85˚ C. Users enjoy enhanced convenience by eliminating chemical handling and disposal concerns.
