1. INTRODUCTION
 HYDAC’spatentpendingdewateringunit(MAFH-A)istherstofitskindonthemarket.TheMAFH-Aoffers
 fullyautomateddewateringofhydraulicuidsandavarietyofotherpetroleumbaseduids.
 TheoperatingprincipleoftheMAFH-Adiffersfromexistingdewateringmethods.TheMAFH-Aisapositivepressuresystem
 thatuses100%masstransfertoremovewaterfromtheoperatinguid.Roomairisheatedusingaproprietarymethodto
 improvetheabilityoftheairtoabsorbwatervapor.Thisheatedairisthendistributedupwardsinthereactionchamber 
 throughcascadingdropletsofoperatinguid.Theheatedairstreamremovesfree,emulsied,&dissolvedwaterandsome
dissolved gases.
 Inmosttraditionalindustrialvacuumdehydrators,masstransferisalsothemeanstodewater.Amild/mediumvacuum 
 expandstheroomairandproportionatelyreducestherelativehumidityoftheair.Theairowislimitedtothedisplacement
 ofthevacuumpump.Higherefciencyvacuumunitsuseaclosedcycletosealoperatinguidwithhighheatandhigh 
 vacuumtoboiloffwater.Theseunitshavehighefciencybuthavelowowratesandcanpotentiallydamagetheoperating
 uidovertime.
 SincetheairowrateoftheHYDAC’sMAFH-Aisnotlimitedbyvacuumpumpdisplacement,itismoreeffectivein 
 dewateringoperatinguidsundersimilarconditionsandowratesthantheabovetechnologies.Inaddition,theMAFH-A
 doesnothavetheinitialandmaintenanceeconomicdisadvantagesofavacuumpumpbasedsystem.
 TheMAFH-Ausesaregenerativeairinjectionsystemtoheatanddistributeroomairintothereactionchamber.Theoptional
 compressedairsystemusesanavailabledried,cleanairsource.Anyresidualuidmistismechanicallyseparatedfromthe
 moistairstreambeforeitisventedfromthechamber.Thesystemuidiscycledthroughthereactionchamberviaasystem
 includingavanepump,twovalves,andthreelters.Duringtherstcycle,uidispumpedandgentlysprayedontopof
 theloose,reticulatedmediauntiltheuidlevelinthesumptriggersthehighoatswitch.Theuidisthenpumpedfromthe
pump and returned to the customer’s reservoir.
 TheMAFH-Aiscontrolledbyacontrolsystemwhichmonitorssystemfunctionandcontrolsthecycleoperation.
 Anon-boardwatersensor(AS1000)monitorstherelativehumidityoftheoperatinguidanddisplaystheactualhumidity
value at the control panel.
