Coalescers

We offer a full range of liquid-liquid and gas-liquid coalescers and coalescing systems for use in various industrial applications to remove particulate matter, water, and other liquids.  The CC Series Liquid-Liquid Coalescers are designed to separate two liquid phases with different characteristics of density, viscosity and interfacial tension (IFT).  They efficiently separate liquid-liquid emulsions in oil, gas, and chemical applications extending equipment life.  The GLP Series Gas-Liquid Coalescers are designed to remove water, carried over amine aerosols and fine particulate from process gas, fuel gas, natural gas, methane, hydrogen and other technical gases.  Coalescers, pre-filters, and full systems are available.

ASCO CC-T Series Liquid-Liquid Coalescers

3.75" and 6"OD Cartridges in Fluoropolymer, Nylon or Polyester Media. The CC-T series coalescing cartridges have been designed to provide high separation efficiencies in those applications where traditional fiberglass cartridges are inefficient.

ASCO CC-M Series Liquid-Liquid Coalescers

2.5" OD Cartridges in Polyester, Polyolefin, or Polyamide Media. The CC-M series coalescing cartridges have been designed to provide high separation efficiencies in those applications where traditional fiberglass cartridges are inefficient.

ASCO LL Systems Liquid-Liquid Coalescers

Liquid-Liquid Coalescers with Cartridge systems - available in vertical and horizontal designs.

ASCO GLP Series Gas-Liquid Coalescers

The GLP series gas-liquid coalescer elements are manufactured with a series of high performance micro fiberglass, polypropylene, polyester or nylon coalescing media in a pleated configuration optimized for liquid separation.

ASCO LG Systems Liquid-Gas Coalescers

Gas-Liquid Coalescers with Cartridge systems - available in vertical and horizontal designs.
