CPVC Intalox Saddle is a material-specific plastic random packing represented in DAIER’s engineering database in 25, 38 and 50 mm sizes. It is most relevant where CPVC compatibility is required and saddle-type geometry suits the tower; final selection should confirm actual chemistry, temperature, mass-transfer duty, fouling, hydraulics, tower diameter and supplier-specific physical data.

CPVC Raschig Ring is a material-specific cylindrical random packing represented in DAIER’s engineering database in 25, 38 and 50 mm sizes. It is most relevant where CPVC compatibility is required and simple Raschig Ring geometry suits the tower; final selection should confirm chemistry, temperature, fouling, hydraulic conditions, tower diameter and manufacturer-specific physical data.

Plastic Q-Pack is a large open-grid random packing with a catalog-confirmed 82.5 × 95 mm geometry, 96.3% free volume, 33.7 kg/m³ bulk density, 1,165 pieces/m³ and a low 23 m⁻¹ dry packing factor. Its strongest engineering position is in towers where hydraulic openness, low bed weight and liquid redistribution are important, while tower diameter, mass-transfer demand, fouling and polymer compatibility still define the final application boundary.

CPVC Pall Ring is a chlorinated-polyvinyl-chloride random packing that combines open Pall Ring geometry with a material position distinct from PVC, PVDF and PTFE. DAIER’s engineering database contains 25, 38 and 50 mm CPVC Pall Ring nodes; final selection should verify actual chemistry, temperature, fouling, hydraulics and manufacturer-specific physical data.

Plastic Raschig Ring is a simple cylindrical plastic random packing available in DAIER’s verified 16–80 mm series. Smaller models provide much greater specific surface area and element count, while the 80 mm model provides a substantially more open bed; final selection should balance polymer compatibility, mass-transfer requirements, hydraulics, fouling, tower diameter and support-grid compatibility.
