Liquid-Liquid Coalescers

CPI “LL” series cartridges are designed to coalesce immiscible non-continuous phase liquids from continuous phase liquids. These liquid-liquid coalescers are available as glass fiber, polyester, polypropylene, and nylon 66 options. 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.

Media choices include glass fiber, polyester, polypropylene, and nylon 66. Micron ratings are available from 0.5 µm to 70 µm.

Threaded Base, Bag Seal, Code 3 O-ring Seal and Code 6 O-ring Seal options for Liquid-Liquid Coalescers.
