Ceramic Mini Lessing Ring – Large Voidage & Low Pressure Drop

Ceramic mini lessing ring is an advanced products based on ceramic raschig ring. It added the Minus partition on the ceramic raschig ring.

The larger size ceramic mini lessing ring (ranging from 80 mm to 200 mm) is commonly be used as supporting packing on the bottom of packed column.

Two ceramic mini lessing rings shows different views.

Ceramic mini lessing ring is used as supporting materials in packed towers.

Features & Benefits

  • Acid and alkali resistance.
  • Large flux.
  • Low pressure drop.
  • High mass transfer efficiency.
