Ceramic Packings

Brief Introduction Ceramic tower packings have great advantage of acid-& heat resistance. It can withstand almost all kinds of acid up to 1000 °C, except HF acid, and be widely used in the tower of dry,absorbing,cooling, washing and recovery etc.in chemical, petrochemical and metallurgical industry.

Ceramic random packings include Rasching ring, Cross partition ring, Pall ring, Intalox saddles, Super Intalox, Cascade ring, Conjugate ring.
