INTERNORMEN Cartridge Filters

PES Pleated Membrane Cartridges, ensure an extended service life, cost-effective & suitable for a variety of aqueous based fluids, e.g. for chemical filtration, deionized water systems, for general use water filtration & liquid clarification. Special designs for food & beverage applications & the electronic industry are also available. Electronics Grade PES Cartridges are designed to meet the special needs of the electronics industry and high purity chemical industries. Polyethersulfone membrane cartridges are resistant to most acids and bases and capable of handling strong sanitization agents. High flow rates make polyethersulfone a good choice for central DI water systems. This membrane will also handle elevated process temperatures in compatible fluids. To minimize extractables, each cartridge module is pulse power flushed until the rinse effluent reaches 18 megohm*cm and less than 3ppb TOC. Each cartridge module is also individually tested.
