Ceramic Raschig Ring – 25 mm to 76 mm options

Ceramic raschig ring is the earliest generation of random packing. The height and diameter of ceramic raschig ring is same and the common specifications are 25 mm to 76 mm.

Ceramic raschig ring has excellent acid resistance and heat resistance performance. It can resist to any inorganic acids, organic acids and organic solvents except for hydrofluoric acid.

The wall thickness of ceramic raschig ring should be thinner under acceptable strength. Though the mass transfer of ceramic raschig ring is low, but it is much cheaper than other random packing, so it is still widely accepted than some industries.
