Plastic Cascade Mini Rings – Maximizing Efficiency in Compact Spaces

When tower space is limited but performance can’t be compromised, plastic cascade mini rings offer a smart solution. Their unique low-profile design—where diameter is about three times the height—creates a stable, evenly distributed bed that enhances gas-liquid interaction without taking up excess volume. We often recommend these rings for applications where fouling is a concern or where a smaller tower footprint is desired, without sacrificing mass transfer efficiency.

What makes these mini rings so effective? Their compact cylindrical shape with internal braces encourages uniform flow distribution, reduces channeling, and minimizes pressure drop. This makes them ideal for continuous-duty systems in gas treatment, chemical processing, and environmental scrubbing where reliability matters.

Clear Specifications – Easy Selection

Model	Dimensions (mm)	Surface Area (m²/m³)	Void Fraction (%)
Dg76	76×38×2.6	90	92.9
Dg50	50×25×1.5	114.2	92.7
Dg38	38×19×1.4	132.5	91
Dg25	25×12.5×1.2	228	90

Where They Perform Best

Methanol and organic acid separation
Desulfurization & decarbonization systems
CO₂ and methane removal
Vacuum distillation and gas dehydration

Why Choose Plastic Cascade Mini Rings?

Even Flow Distribution: Low aspect ratio minimizes channeling and improves contact
Fouling Resistance: Open structure allows solids to pass through more easily
Space-Saving: Ideal for compact or retrofitted tower designs
Mechanical Strength: Suitable for deep beds without deformation

If you’re looking for a packing that balances efficiency, fouling resistance, and space constraints, plastic cascade mini rings deliver consistent performance in a compact, durable form.
