EXF Series 14 x 40

Summary

Product identification

The 3M™ Liqui-Cel™ EXF-14x40 Series is a membrane contactor designed for O₂ removal from liquid and other gas transfer applications.

Operating limits

• Liquid Flow Guidelines: 16 – 125 m³/hr (70 – 550 gpm)
• Maximum Shellside LIQUID Working Temperature/Pressure:
  • 5-25°C, 7.2 barg (41-77°F, 105 psig)
  • 50°C, 2.1 barg (122°F, 30 psig)
  • 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)
  • Note: Maximum applied gas pressure is for integrity testing at ambient temperatures; normal operating pressures are typically lower.
• Liquid pressure should always exceed gas pressure.
• Pressures are based on fluid group 2 (other) liquids and gases per the European Union Pressure Equipment Directive 2014/68/EU. See Operating Guide for pressure limits in the European Union with fluid group 1 (hazardous) liquids and gases. Also, see Operating Guide for complete temperature/pressure limits for housings and membrane.

Performance Characteristics

Performance curves for O₂ removal and pressure drop are available, generated using water at 20°C. O₂ removal test conditions involved X40 membrane in N₂-vacuum combo mode, with vacuum at 50 torr and N₂ at 0.8 scfm. Characteristics may change under different operating conditions. See the official PDF for exact tabulated values and performance curves.
