Hilco® Selexsorb GT Filter Cartridges and Systems - 1

Hilco® Selexsorb GT Filter Cartridges and Systems Fewer fluid changeouts, increased equipment life Cartridges fit most standard Hilco filter housings Lifting handle - for convenience in handling. Ambient - Perforated steel or expanded metal ambient provides added strength. Lifting tab - for convenience in handling. Polyester media retainer - under the ambient for superior chemical resistance and media retention. Selexsorb GT is a patented adsorbent specifically designed for use with Fyrquel gas turbine lube and hydraulic control fluids. Another application is steam turbine EHC control industrial hydraulic systems. The unique composition of this adsorbent maintains the original, superior properties of these fluids for prolonged periods. This media, in cartridge form, is available through your authorized Hilco distributor. Benefits When Hilliard systems are used in conjunction with a fluid maintenance program designed by your Fyrquel supplier, you can expect the following benefits: • Longer fluid life - Fluid changeout intervals are greatly lengthened, and the fluid is maintained in near-original condition. • Increased equipment life - A result of continual removal of acid phosphates and moisture. • Standard sizings - Designs fit most standard Hilco filter housings (e.g., 718, 119). Superior efficiency - Maintains total acid number (TAN) much more effectively than fuller’s earth. Advantages versus other filter types The key features of Selexsorb GT cartridges and systems over conventional fuller’s earth and activated alumina are as follows: • Fuller’s earth - Low comparative removal of acid phosphates; acid removal relies upon neutralization with media surface. Major disadvantage is presence of metal impurities. • Activated alumina - Acid capacity is 2-3 times that of fuller’s earth; relies on neutralization of media surface with acid phosphates. Again, basic metal impurities can create similar problems as with fuller’s earth through extended use. • Selexsorb GT - Similar acid capacity to activated alumina types. However, acid phosphates are adsorbed or chemically bonded to the surface of the filter media as they are formed. A neutralization reaction is not involved nor are free ionic metals liberated in the hydraulic system. Also can remove moisture but preferentially bonds acid phosphates in lieu of moisture. Cartridge life can be extended 2-3 times versus fuller’s earth. Flow rate in auxiliary filter system must be slowed to allow chemical exchange to occur. Normal rate is 1/2 GPM maximum per 7” x 18” Selexsorb GT cartridge. NOTE: Ideally, acid number should be maintained below a level of 0.1 TAN. Similarly, a moisture level of less than 0.1% (by weight) is desirable. ® Hilco is a registered trademark of the Hilliard Corporation.
