4 FEATURES: • Cost effective particle and emulsified water removal from hydrocarbon fluids • Easy installation and replacement with one-piece design • Choice of Threaded Base or Open End cartridges • Choice of All-Fiberglass Media or Combination Fiberglass and Pleated Media • Field proven performance • Ongoing qualification testing to meet changing commercial and military requirements • Used as a first-stage cartridge in Filter/Separatos • Remove particulates and coalesce water into large water drops • Also available in screw base design HOW COALESCERS WORK: Coalescer cartridges are employed as the first stage in filter/separator vessels for hydrocarbon fluids. They perform two functions: (1) coalesce (combine) highly dispersed, emulsified water particles into larger water drops and (2) filter-out particulate contaminants. The left photo below shows a highly magnified viewof the coalescing process. Tiny droplets of water contact and adhere to strands of fiberglass. Flowpushes the droplets along the strand until they reach an intersection of strands where they combinewith other droplets (coalesce) into large drops. These large drops are then carried to the outside surface of the cartridge. Having a higher specific gravity than the hydrocarbon fluid, they release and gravity pulls the droplet to the bottom of the vessel. The larger the drops, the faster and more efficiently they fall out. (See top right photo.) In general, particle removal efficiency increases with coalescing efficiency.
