Ceramic Mini Lessing Ring is a partitioned ceramic random packing that provides additional gas-liquid contacting surface compared with a simple Raschig Ring. Its suitability depends on process chemistry, temperature, hydraulic requirements, fouling risk, packing size, bed weight and whether the additional internal structure provides a meaningful process advantage.

Ceramic Berl Saddle is a saddle-shaped ceramic random packing used in compatible corrosive and high-temperature packed-tower services. Selection should consider chemistry, temperature, hydraulic requirements, packing size, bed weight, brittleness and whether a traditional Berl Saddle or a later packing geometry better fits the process.

Tri-Pack-type random packing is a highly open plastic packing used primarily where hydraulic capacity, corrosion resistance, low bed weight and fouling tolerance are important. Its suitability should be determined from actual gas and liquid loads, required mass transfer, polymer compatibility, packing size and tower conditions.

Teller Rosette is a lightweight, highly open plastic random packing commonly considered for gas scrubbing and absorption applications. Its selection should balance hydraulic openness, mass-transfer requirements, polymer compatibility, fouling conditions, packing size and tower geometry.

Super Raschig Ring-type packing is an advanced random packing geometry designed to combine high hydraulic openness with effective gas-liquid contacting. It is especially relevant to capacity- and pressure-drop-sensitive towers and retrofit projects, but selection should still consider packing size, fouling, material compatibility and existing tower internals.
