Conjugate Ring Packing – Conjugate Curved Surfaces to Prevent Nesting

Conjugate Ring Packing features a unique conjugate-curved fin structure that replaces linear contact between packing elements with point-to-point contact. As a result, it promotes uniform liquid distribution, prevents packing overlap, and improves liquid collection and dispersion.

After Conjugate Ring Packing is loaded into a scrubber or absorption tower, the rings form interlaced gas–liquid flow channels that guide the liquid to spread in different directions, reducing packing nesting, channeling, and localized dry zones.

Two plastic conjugate rings placed together

Features

Conjugate curved-surface structure. The interlaced curved surfaces guide the liquid to change direction.
Resists nesting. The asymmetric open structure reduces nesting between packing elements.
More uniform liquid distribution. Helps disperse the liquid throughout the packing bed and reduce channeling.
Rapid liquid-film renewal. The curved surfaces and ribs continuously divide and recombine the liquid flow, continually renewing the wetted surface.
