Proware™ silica-alumina ceramic formulation is virtually iron-free and has a finely-grained microstructure resistant to alkalis, solvents, and acids with the exception of hydrofluoric acid.

Proware™ body is the standard material for all Saint-Gobain NorPro mass transfer products. The Proware™ body results in high strength, low porosity, and chemically resistant tower packings.

Maximum Operating Temperature	1100ºC
Leachable Iron	≤ 0.01%
Acid Resistance (≤50mm saddle sizes)	≤ 4.0%
Acid Resistance (75mm saddle sizes)	≤ 6.8%
Porosity (as measured by water absorption)	≤ 0.4%
Crush Strength (for ≥25mm saddle sizes)	120 lbs. min. (54 kg)

For superior mass transfer performance, the unique scalloped edge and strategically placed holes of the Proware™ Super Saddle results in maximum usable area for liquid/gas contact and minimum resistance to flow through the column. Thus, the Proware Super Saddle provides 5 - 30% greater mass transfer efficiency and 25% lower pressure drop than the corresponding size standard saddle.
