Ceramic Intalox Saddles for dry tower

Ceramic saddle is improved from the arc saddle, it is widely used in suphuric acid plants.

Ceramic saddle is improved from the arc saddle, it changes the both arched surface to rectangular surface and makes the interior and exterior radius of curvature different, this construction overcomes the problem of nesting basically, and it makes porosity distributed even and improves the distribution of the fluid, and greater capacity and lower pressure drop than Raschig ring.

They are available in variable sizes such as (mm): 12, 16, 19, 25, 38, 50, 76.
