Summary

Product identification

• Model: 80E45 Fiberglass RO Pressure Vessel
• Intended Use: Housing for reverse osmosis membrane elements to desalt typical brackish waters. Accommodates any make of eight-inch nominal diameter spiral-wound element.

Operating limits

• Design Pressure: 450 PSI at 120°F (3.1 MPa @ 49°C)
• Minimum Operating Temperature: 20°F (-7°C)
• Factory Test Pressure:
  • CE: 675 PSI (4.65 MPa)
  • ASME: 585 PSI (4 MPa)
• Burst Pressure: 2700 PSI (18.6 MPa)
• Maximum Permeate Pressure: 125 psi at 120°F (0.9 MPa @ 49°C)
• Operating pH Range: 3 to 10

Feed water

• Suitable for typical brackish waters.
• Operating pH Range: 3 to 10

Mechanical / hydraulic

• Accommodates any make of eight-inch nominal diameter spiral-wound element.
• Fiberglass shell expansion under pressure:
  • ΔDIA = 0.02 in. (0.5 mm)
  • ΔL = 0.2 in. (5 mm) for a length code –6 vessel
• Maximum weight of branch piping supported by ports:
  • Feed/Concentrate: 16 lbs (7 kg)
  • Permeate: 8 lbs (4 kg)

Precautions

• Read, understand, and follow all instructions; failure to take every precaution will void warranty and may result in vessel failure.
• Mount the shell on horizontal members at span "S" using compliant vessel supports furnished; tighten hold-down straps just snug.
• Provide overpressure protection for the vessel set at not more than 105% of design pressure.
• Inspect end closures regularly; replace components that have deteriorated and correct causes of corrosion.
• Do not make rigid piping connections to ports or clamp the vessel in any way that resists growth of the fiberglass shell under pressure.
• Do not hang piping manifolds from ports or use the vessel in any way to support other components.
• Do not operate the vessel at pressures and temperatures in excess of its rating.
• Do not operate the vessel without permeate ports internally connected with a complete set of elements and interconnecting hardware.
• Do not operate the vessel with permeate pressure in excess of 125 psi at 120°F (0.9 MPa @ 49°C).
• Do not overtighten the connection to the permeate port (hand-tighten plus one-quarter turn, check for leaks).
• Do not tolerate leaks or allow end closures to be routinely wetted in any way.
• Do not pressurize the vessel until double-checking to verify that the retaining ring is completely inside the groove.
• Do not work on any component until first verifying that pressure is relieved from the vessel.
• Do not operate at pH levels below 3 or above 10.

Ordering Information

When ordering, specify:
