PVDF Intalox Saddle is a fluoropolymer random packing that combines chemically resistant PVDF construction with open saddle-type geometry. DAIER’s engineering database currently contains 25, 38 and 50 mm PVDF Intalox Saddle nodes; final selection should confirm chemistry, temperature, fouling, hydraulics, tower diameter and manufacturer-specific product data rather than treating PVDF as an automatic performance upgrade.

PTFE Intalox Saddle is a fluoropolymer random packing that combines chemically demanding PTFE construction with open saddle-type gas-liquid contacting geometry. DAIER’s engineering database currently contains 25, 38 and 50 mm nodes; final selection should confirm chemistry, temperature, fouling, hydraulics, tower diameter and manufacturer-specific product data rather than assuming PTFE itself guarantees better tower performance.

Plastic Igel Ball is a distinctive 40 mm plastic random packing with numerous radial projections and a verified specific surface area of approximately 300 m²/m³. Its selection should balance contacting-area requirements against 87% void fraction, hydraulic limits, fouling, tower diameter and polymer compatibility rather than treating the spiked geometry as an automatic efficiency or anti-fouling advantage.

PVDF Pall Ring is a fluoropolymer random packing that combines open Pall Ring geometry with PVDF material for chemically demanding packed-tower service. DAIER’s engineering database currently contains 25, 38 and 50 mm PVDF Pall Ring nodes; final application should confirm process chemistry, temperature, fouling, hydraulic conditions and manufacturer-specific product data rather than treating PVDF as an automatic performance upgrade.

PVDF Raschig Ring is a fluoropolymer random packing represented in DAIER's engineering database in 25, 38 and 50 mm sizes. Selection should first establish whether PVDF is truly required by the chemistry and temperature, then balance packing size against mass transfer, hydraulic openness, fouling, tower diameter and retrofit compatibility.
