Plastic Pall Rings – Reliable Performance for Everyday Processes

When you need a packing that balances performance, cost, and durability, plastic pall rings are a proven choice. Their unique design—featuring large side windows and internal crossbars—creates an open structure that promotes excellent vapor-liquid contact without high pressure drop. We often recommend them as a go-to solution for standard absorption, stripping, and treatment tasks where corrosion resistance and economical operation matter.

What makes these rings work so well? The windows allow fluids to pass through freely, while the crossbars help break up liquid flow into thin films. This means better distribution and higher efficiency compared to old-style solid rings. Plus, plastic construction gives you solid chemical resistance at a fraction of the metal or ceramic cost.

Clear Specifications – Easy Sizing

Model	Dimensions (mm)	Surface Area (m²/m³)	Void Fraction (%)
Dg16	16×16×1.0	188	91.1
Dg25	25×25×1.2	175	90
Dg38	38×38×1.4	155	89
Dg50	50×50×1.5	93	90
Dg76	76×76×2.6	73.2	92

Where They Excel

Water and wastewater treatment
CO₂, SO₂, HCl, and HF gas absorption/stripping
Drinking water purification
Odor control and chlorine scrubbing

Why Choose Plastic Pall Rings?

Good Distribution: Uniform flow leads to consistent performance
Corrosion Resistant: Handles many chemicals without degradation
Cost-Effective: Lower price point than metal, with solid performance
Fouling Resistant: Open design reduces clogging risk

If you’re looking for a dependable, all-around packing for standard chemical or environmental applications, plastic pall rings deliver proven value day after day.
