Summary
Product identification
Sanitary Stainless-Steel Membrane Housings designed for Reverse Osmosis (RO), Nanofiltration (NF), and Ultrafiltration (UF) applications. These are 3A approved 8-inch side entry housings, combining a rugged design with over 30 years of application history. The design and fabrication of the membrane housing and endcap have been reviewed and approved by the USDA.
Features and Benefits
- Design:
- Largest port available in any membrane housing design, allowing for superior flow and reduced pressure drop.
- All ports are tri-clamp connections with 180 grit polished ID.
- Welds and edges are polished to be smooth and tapered, eliminating potential for product hold-up.
- No seals involved in side port connections.
- 3A approved design (for 802P – 3A option).
- Material (Stainless Steel):
- Unlike fiberglass, it doesn't warp or weep.
- Is not affected by UV rays or sunlight.
- Preferred and universally accepted material for water systems and sanitary process applications.
- Capable of supporting process piping.
- Lighter and easier to handle than PVC and FRP housings with equivalent pressure ratings during assembly.
- Finish:
- Superior finish options include electro polishing, mechanical polishing, or metallic two-coat epoxy paint.
Operating limits
- Design Pressure: 600 psi
- Tested Pressure: 3 times design pressure
- Tested Cycles: 100,000 cycles at design pressure
