SanRO HS-4

Summary

Product Identification

SanRO-HS Heat Sanitizable, High Rejection Reverse Osmosis Composite Membrane Elements are designed for high performance in USP and other high-purity water systems. These elements feature sanitary, full-fit outer-wraps to eliminate "dead flow" areas for maximum bacteria control. SanRO-HS components conform to FDA regulation CFR Title 21.

• Configuration: Sanitary (Full-Fit) Spiral Wound
• Membrane Polymer: Composite Polyamide
