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. Food & Beverage Grade PES Cartridges are designed to meet the needs of the Food & Beverage industry. Polyethersulfone membrane cartridges are resistant to most acids & bases and are capable of handling strong sanitization agents. High flow rates make polyethersulfone a good choice for Food & Beverage applications. This membrane will also handle elevated process temperatures in compatible fluids. To minimize extractables, each cartridge module is rinsed with a high purity flush system. Each cartridge module is also individually tested for integrity using the diffusional flow method.
