Ceramic Pall Ring
– Advanced Products of Raschig Ring
Ceramic Pall ring is the advanced products of ceramic Raschig ring. Compared with ceramic Raschig ring, there are two layers of window on the cylinder wall. And each layer has five ligules bending inward.
This design makes the surface area and voidage be improved and the porosity be evenly distributed. Additional, it has greater capacity and lower pressure drop than ceramic raschig ring.
Features & Benefits
- Excellent heat and acid resistance.
- Higher capacity.
- Lower pressure drop.
- Evenly distributed porosity and fluid.
Applications
- Ceramic pall ring can be used in high or low temperature conditions.
- It can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industries, etc.
