ceramic lessing ring

Item Code: Features:
  • Description
Ceramic Lessing Ring (also named as Ceramic One Ring or Ceramic Partition Ring) is a tower packing in mass transfer application, designed basically from the Raschig Ring with the partitions inside to increase the surface and enhance the transfer efficiency. It is usually used extensively for the supporting packing at the bottom of tower. And Ceramic Lessing Ring also as an important heat transfer media, used in the heat exchage system, Regenerative Thermal Oxidizer system (RTO system),which is instead of ceramic saddle.
Details

鈽匒s tower packing in mass transfer application, Ceramic Lessing Rings are available in variable sizes such as (mm): 50, 80,100,120,150mm.
