Plastic Ralu Ring is a refined version of the pall ring, distinguished by its expanded end flanges and thicker walls. This design’s open configuration optimizes flow dynamics and mitigates pressure drop. As a set of two open-ended cylindrical shapes, the Plastic Ralu Ring features a low mass transfer unit, reduced pressure loss, decreased specific weight, an elevated flood point, substantial void fraction, and superior mass transfer capabilities.

This Plastic Ralu Ring is characterized by its substantial free volume, minimal pressure, compact mass transfer unit height, elevated flooding point, consistent gas-liquid interfacing, reduced specific gravity, and superior mass transfer efficiency. It is designed to operate effectively within a medium temperature range of 60°C to 280°C.

The Plastic Ralu Ring is ideal for a variety of separation, absorption, and desorption apparatus, as well as atmospheric and vacuum systems, synthetic amine decarburization, desulfurization processes, and separation tasks involving ethylbenzene, isooctane, and toluene.

Ralu Ring Features:

Elevated void fraction.
Minimal pressure drop.
Reduced mass transfer unit height.
High flooding point.
Uniform gas-liquid contact.
Low specific gravity.
Enhanced mass transfer efficiency.

Key Advantages:

Its unique structure facilitates a significant flow rate, low pressure drop, and robust resistance to impact.
Exhibits strong chemical corrosion resistance, ample void volume, energy efficiency, reduced operational costs, and ease of installation and removal.


Extensively used in a range of separation, absorption, and desorption equipment.
Employed in atmospheric and vacuum distillation setups.
Utilized in decarburization and desulfurization systems.
Applied in the separation processes of ethylbenzene, isooctane, and toluene.
