Ceramic Raschig Ring – 25 mm to 76 mm options

Five different sizes of ceramic raschig rings on blue background.

Ceramic raschig ring has simplest structure.

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.

Features & Benefits

  • Economical and low price.
  • Simple structure.
  • Acid and alkali resistance.
  • High or low temperature resistance.

Applications

  • It is widely used in high or low temperature conditions.
  • Ceramic raschig ring is widely used in the drying tower, absorption tower, cooling tower and washing towers in chemical, metallurgy, coal gas, industrial oxygen production industries.
