IntegraPac IPD 77

Summary

Product identification

The DOW IntegraPac™ Ultrafiltration Skid for Potable Use with IPD-77 modules is a pre-engineered, standardized skid design. It consists of DOW IntegraPac™ Ultrafiltration modules, auxiliary parts, and piping, designed to streamline design, assembly, and installation.

Key features include:

• Skid tested and certified by NSF International under NSF/ANSI Standard 61 ensuring safe use in drinking water applications.
• NSF Public Drinking Water Equipment (PDWE) Certification on module IPD-77.
• No ancillary piping, manifolds and connections due to direct coupling of modules, saving cost and reducing footprint.
• Modular and scalable for design across a wide range of flow rates.
• Materials of construction selected for corrosion resistance and chemical compatibility.
• Shipped unassembled to lower transportation cost for the customer and help prevent damage in transit.
• Standardized and pre-fabricated components and parts eliminate measuring, cutting, gluing and welding.
• Easily accessible for physical inspection or replacement at end of life.
• Operator-friendly transparent filtrate elbow designed and located for easy visual integrity inspection.
• High pressure rating to enable direct feed to reverse osmosis feed pumps.
