Ceramic Random Packing
Inert, high-temperature ceramic random packing for hot gas, strong-acid service, thermal oxidisers and catalyst-bed support.
Why choose Ceramic Random Packing
Ceramic random packing is inert and stable at high temperature, handling hot gas and strong acids (except HF) where metal and plastic cannot. It is the standard choice for drying and absorption towers, tail-gas scrubbers, thermal oxidisers and catalyst-bed support. PCX supplies ceramic packing sourced from qualified international partners and supplied to your specification across Thailand.
Ceramic Intalox Saddle
A saddle shape intermediate between a ring and a classic saddle, keeping the advantages of both and aiding liquid–gas distribution. The smooth ceramic surface gives high chemical resistance and stability, produced economically by continuous extrusion. Acid resistance >99.6%, max operating temperature 1,100 °C, water absorption <0.3%, Mohs hardness >6.5.
- Ceramic — SiO₂ >73%, Al₂O₃ 17–23%
Applications: scrubbers, drying towers, tail-gas scrubbers, absorption, cooling and regeneration towers; heat-transfer media in Regenerative Thermal Oxidisers (RTO)

Ceramic Raschig Ring
The earliest random-packing geometry — a simple cylinder of equal height and diameter, with a surface ratio about 30% higher than ceramic cylinders or balls and high mechanical stability. Excellent acid resistance to inorganic and organic acids and solvents (except hydrofluoric acid) and high-temperature tolerance. Large sizes (≥100 mm) are stacked; smaller sizes are dumped.
- Ceramic — acid- and heat-resistant
Applications: chemical, metallurgy, gas and environmental industries: drying, absorption, cooling and regeneration towers and scrubbers

Inert Ceramic Ball
Chemically stable ceramic ball with low water absorption, resisting high temperature and pressure, acids, alkalis and many solvents, and withstanding thermal shock. It increases gas/liquid distribution points at the top of reactor beds and supports and protects low-strength catalyst beds from the mechanical stress of flow.
- Inert ceramic (alumina)
Applications: catalyst-bed supports and top plugs in petrochemical, chemical, fertiliser, natural-gas and environmental units: ammonia plants, hydrotreaters, isomerisation, chloride absorbers, Claus units, molecular sieves, hydrocrackers, hydrogen plants, reformers

Frequently Asked Questions
When should I use ceramic random packing?
Ceramic random packing is chosen for hot gas streams (above roughly 200 °C, up to 1,100 °C), strong acid service (except hydrofluoric acid), heat-transfer media in Regenerative Thermal Oxidisers (RTO), and inert catalyst-bed support and protection.
What acids and temperatures does ceramic packing resist?
Ceramic packing has an acid resistance above 99.6% and a maximum operating temperature up to 1,100 °C. It resists inorganic and organic acids and many solvents — the main exception is hydrofluoric acid (HF).
What is the difference between the saddle, ring and inert ball?
The Intalox saddle gives the best liquid–gas distribution and low pressure drop; the Raschig ring is a simple, mechanically robust cylinder for absorption and drying towers; and the inert ceramic ball is used mainly to support and protect catalyst beds and to spread flow at the top of reactor beds.
Ceramic, metal or plastic random packing — what is the difference?
Ceramic is inert and handles hot gas and strong acids (except HF) but is heavier and more brittle. Metal offers the highest strength and lowest pressure drop for high-temperature, deep-bed service. Plastic gives corrosion resistance at low weight and cost but is temperature-limited. We supply all three families.
Do you supply ceramic random packing in Thailand, and how do I get a quotation?
Yes. PCX supplies ceramic random packing and inert ceramic ball across Thailand, sourced from qualified international partners and supplied to your specification. Send us the service, geometry, size and volume — or your reactor/column data — and we will return a quotation.
