Ceramic Pall Ring Product advantages

Excellent Acid & High Temperature Resistance

Strong chemical stability against most inorganic acids, organic acids and solvents; works stably under high temperature corrosive working conditions, far better than plastic and metal packing

Low Pressure Drop & Energy Saving

Unique open window structure brings high void fraction, smaller gas flow resistance and lower tower pressure drop, effectively cutting power consumption of fans and compressors during long-term operation。

High Mass Transfer & Separation Efficiency

Inner flanges split liquid flow evenly to avoid channeling inside the tower, enlarge gas-liquid contact area, greatly improve absorption, distillation and desulfurization efficiency compared with Raschig ring。

Anti-clogging & Long Service Life

Smooth ceramic surface and hollow structure are not easy to accumulate dirt and blockage; high mechanical hardness and wear resistance reduce replacement frequency and maintenance cost

Wide Application Compatibility

50mm standard size fits most industrial packed towers, widely applicable to waste gas purification, chemical separation, drying tower, scrubber tower and metallurgy gas treatment projects。

Ceramic Pall Ring Product Introduction

50mm ceramic pall ring is a widely used random tower packing made of high-alumina ceramic material. It is upgraded on the basis of Raschig ring with open window and inner tongue structure, which effectively overcomes the defects of easy liquid channeling and poor gas-liquid contact of traditional ring packing.50mm ceramic pall ring is a widely used random tower packing made of high-alumina ceramic material.

special structural design greatly increases the specific surface area for gas-liquid contact, enhances mass transfer and separation efficiency, and the smooth ceramic surface is not easy to adhere impurities, with strong anti-clogging ability and long service life, greatly reducing later maintenance and replacement costs.

1.Superior High Temperature Resistance

It can continuously work under working temperature up to 1050℃, stable structure without deformation or cracking under high thermal environment.

2.Outstanding Corrosion Resistance

Able to resist erosion of most inorganic acids, organic acids and organic solvents; only ineffective against hydrofluoric acid and strong alkali under extreme conditions.

3.Low Pressure Drop & High Void Rate

High void fraction reduces gas flow resistance inside the tower, lowers system pressure drop and cuts energy consumption of fans and compressors.

4.Efficient Gas-liquid Mass Transfer Performance

Unique punched window structure enlarges contact area between gas and liquid, avoids liquid channeling, and greatly improves separation and absorption efficiency.

5.Good Anti-blocking & Mechanical Properties

High hardness and wear resistance, smooth surface not easy to stick dirt, not prone to blockage, with long service cycle and low maintenance cost.
