Conjugate Ring is an open metal or plastic random packing designed to balance hydraulic capacity, pressure-drop tendency and gas-liquid mass transfer. Selection should consider packing size, process duty, fouling, material compatibility, tower diameter and whether its geometry provides a meaningful advantage over conventional random packing.

Dixon Ring is a small, high-efficiency metal random packing particularly suited to clean laboratory, pilot and small-diameter separation columns. Its selection should balance mass-transfer efficiency against pressure drop, hydraulic capacity, fouling sensitivity, alloy compatibility and column diameter.

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.
