Coalescer Filter Systems

Tiny droplets of water adhere to strands of fibreglass.  Flow pushes the droplets along the strand until they reach an intersection of strands where they combine with other droplets(coalesce) into large droplets.

These larger droplets are then carried to the outside surface of the cartridge.  Having a higher specific gravity than the hydrocarbon fluid, they release and settle at the bottom of the vessel.  The larger the drops the faster and more efficiently they fall out.  In general, particle removal efficiency increases with coalescing efficiency

This is accomplished by employing a tighter, finer filtration media.  Flow direction is from inside to outside of the cartridge.  This minimizes surface velocity and helps prevent the water drops from breaking up and being carried downstream
