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.
