Liquid-Liquid Coalescers

Threaded Base, Bag Seal, Code 3 O-ring Seal and Code 6 O-ring Seal options for Liquid-Liquid Coalescers.Champion Process, Inc's “LL” series cartridges are designed to coalesce immiscible non-continuous phase liquids from continuous phase liquids. As fluid passes through these LL coalescers and across the media the tiny suspended droplets of the non-continuous phase are brought together into larger droplets. These larger droplets respond faster to gravity and the two phases separate.

Liquid-Liquid Coalescers Materials

These liquid-liquid coalescers and liquid-liquid separators media choices are available as glass fiber, polyester, polypropylene, and nylon 66. Micron ratings are available from 0.5 µm to 70 µm.
