SP Series 2.5 x 8

Summary

Product identification

3M™ Liqui-Cel™ SP-2.5x8 Series Membrane Contactor

Membrane Characteristics

• Cartridge Configuration: Extra-Flow with Center Baffle
• Membrane/Potting Material: Polyolefin / Polyethylene
• Priming Volume:
  • Shellside: 0.23 liters (0.06 gal)
  • Lumenside: 0.09 liters (0.02 gal)

Operating limits

• Liquid Flow Guidelines (Shellside): 0.1 – 0.7 m³/hr (0.5 – 3 gpm)
  • Liquid must flow on the shellside.
• Maximum Shellside LIQUID Working Temperature/Pressure:
  • 5-25°C, 4.1 barg (41-77°F, 60 psig)
  • 50°C, 1.0 barg (122°F, 15 psig)
  • Note: If no vacuum is used, 1.0 barg (15 psig) can be added to pressures above.
• Maximum Applied Gas Pressure: 4.1 barg at 25°C (60 psig at 77°F)
  • Max applied gas pressure is for integrity testing at ambient temperatures. Normal operating pressures are typically lower.
• General Note: Liquid pressure should always exceed gas pressure.
• Operating Guide: See Operating Guide for complete listing of temp/pressure limits for housings and membrane.

Housing Characteristics

• Material: Polypropylene
• Flange Connections:
  • Shellside (Liquid Inlet/Outlet):
    • ¼ inch NPT female
    • 3/8 inch Flaretek® (nut included)
    • ½ inch Flaretek® (nut included)
  • Lumenside:
    • ¼ inch NPT female
• Seal Options:
  • Fluoroelastomer: General Purpose
  • Perfluoroelastomer: Ultra Pure Water
• Weight (approximate):
  • Dry: 0.5 kg (1.1 lbs)
  • Water-Filled (shellside): 0.7 kg (1.6 lbs)

Mechanical / hydraulic

• Dimensions (nominal values for contactors with NPT connections):
  • Diameter: 77 mm (3.1 in), 67 mm (2.6 in)
  • Length: 277 mm (10.9 in), 255 mm (10.0 in)
  • Note: Overall length with Flaretek connections increases. Refer to 3M.com/Liqui-Cel for detailed housing drawings.

Regulatory

• Complies with the limits as set by RoHS Directive 2011/65/EU Annex II; recasting 2002/95/EC.
• Constructed of FDA CFR title 21 compliant materials for wetted parts only at ambient temperatures.

Performance Graphs

The datasheet includes graphs illustrating performance characteristics:

• Pressure Drop vs. Water Flow Rate: Shows how pressure drop (in bard and psid) changes with increasing water flow rate (in m³/hr and gpm).
• Oxygen Removal % vs. Water Flow Rate: Shows the percentage of oxygen removal relative to water flow rate (in m³/hr and gpm) at different vacuum levels (50 torr, 75 torr).
• Test condition for O₂ Removal: Vacuum mode with water at 20°C. Characteristics may change under different operating conditions.
