PX PAN 400kDa

Summary

Product Identification

This is a Sanitary Ultrafiltration (UF) Spiral-Wound Element, model PX (PAN 400kDa) from Synder Filtration. These elements offer an optimal combination of flux and rejection over a comprehensive range of molecular weight cut-offs (MWCOs).

Operating Limits

• Maximum Temperature: 55°C (131°F)
• pH Range @ Max Temperature: 3-10.5
• pH Range @ Ambient Temperature: 3-10
• Maximum Inlet Pressure: 120 PSI (8.3 Bar)
• Minimum Outlet Pressure: 10 PSI (0.7 Bar)
• Maximum Differential Pressure per Element: 18 PSI (1.2 Bar)
• Maximum Permeate Backpressure: 5 PSI (0.3 Bar)

Note: Soft start on boost pumps is required to minimize pressure/flow shocks to elements.

Cleaning Parameters

• Maximum Temperature (Short term <30 min): 50°C (122°F)
• pH Range @ Max Temperature: 3-10.5
• pH Range @ Ambient Temperature: 3-10
• Free Chlorine During Operation:
  • Norm ppm: 0
  • Max ppm: <0.1
• Chlorine During CIP (Clean-in-Place) at pH 10.8-11.0 and 50°C:
  • Norm ppm: 150
  • Max ppm: 180

Note: Maximum chlorine exposure for all elements is 30 minutes per day at pH and temperature conditions listed above.

Feed Water

The datasheet provides a table for Dairy Product Total Solids Limits based on different feed spacer (mils) for Sweet Whey, Acid Whey, Skim Milk, and Whole Milk. See the official PDF for exact tabulated values. Note: Trials should be made to determine temperature and viscosity effects.

Mechanical / Hydraulic

The elements are available in various dimensions (Diameter, Length) and Permeate Water Tube (P.W.T.) Inner Diameters (ID). Weights are also provided per model. Examples include:

• 1812F: 1.8 in OD, 12 in Length, 0.63 in PWT ID, 1.0 lb (0.5 kg)
• 2540F: 2.5 in OD, 40 in Length, 0.63 in PWT ID, 4 lb (1.8 kg)
• 3838: 3.8 in OD, 38 in Length, 0.83 in PWT ID, 10 lb (4.5 kg)
• 6438: 6.4 in OD, 38 in Length, 1.14 in PWT ID, 29 lb (13.2 kg)
• 10338: 10.3 in OD, 38 in Length, 1.14 in PWT ID, 50 lb (22.7 kg)

Some models, like 2540M, feature 1” permeate tube extensions (0.75” OD). See the official PDF for a complete list of element dimensions and weights. Different diameters are available, and custom dimensions can be designed.

The datasheet also provides tables for Membrane Area (Sq. Ft.) and Recommended Element Cross Flow Rate (in m³/hr and gpm) for various models and feed spacer sizes. See the official PDF for exact tabulated values for Membrane Area and Recommended Element Cross Flow Rate. Note: The recommended cross flow rate will be subject to differential pressure limitations and specific applications.
