Ka 1970, US Steel Corporation e ile ea haha ntlo-kholo e ikhethang e ntseng e e-na le lipale tse 64 ka holimo ho Pittsburgh, Pa., skyline. E hahiloe ho nka lilemo tse 100, skyscraper eo hona joale e tsejoang e le US Steel Tower e ikhethile ka meralo. E na le sebaka se ikhethileng sa khutlo-tharo se sebelisang tšepe ea COR-TEN® e ntlafalitsoeng ea US Steel ho theha sistimi ea kantle e lumellang pale e 'ngoe le e' ngoe hore e be le acre ea sebaka sa fatše. Ha e ntse e le pele ho nako ea eona lilemong tsa bo-1970, mohaho o ile oa oela ka morao ka thepa ea mechine e kentsoeng ha li-kilowatt li bitsa lipeni le oli e le $ 3 ka barrel. Ke ka lebaka leo Winthrop Management, molaoli oa thepa ea moaho, a ileng a qala letoto la lipeeletso ka ho sebelisa li-Danfoss variable frequency drives (VFDs) ho fokotsa litšenyehelo tsa matla - e leng se ileng sa fella ka ho boloka matla a fetang $1 milione le botumo bo botala bo hohelang bahiri.
"Re 'nile ra sebelisa Danfoss VLT® Drives mererong e fapaneng ea ho khutlisetsa chelete ka lilemo tse ka bang 15," ho bolela Gary Sechler, mookameli oa boenjiniere oa Winthrop Management. "Kamora karolo e 'ngoe le e 'ngoe ea morero oa ho khutlisetsa chelete, re fumane hore chelete ea ho baballa lienjene tsa pompo le balateli e bile ntle haholo. Kahoo re ne re tla kena mohatong o mong.

Sechler o re: “Re tsamaisa metsi a mangata le moea holimo, tlase le ho potoloha moaho ona. “Metsi a fanoa ka liphaephe tse peli tsa metsi tse sa hlokeng letho. Ho feta moo, ho na le lipompo tse 'ne tse sa sebetseng, tse 100-HP tsa metsi moahong. E mong le e mong a ka sebeletsa mohaho oohle, haeba ho hlokahala.

Morero oa pele oa ntlafatso ea VFD e ne e le ka selemo sa 2000 ha VLT® Drives e sebelisoa ho li-motor tse 'ne tsa 100-HP tse ikarabellang bakeng sa phepelo ea metsi ea lehae.
Jim Rice, mong'a M&R Affiliates, moemeli oa thekiso ea Danfoss ea ntseng a sebetsa le Sechler o re: "Likoloi tsa khale e ne e le li-drive tse peli joalo ka ha li ne li sebelisoa litsing tsa tšepe mehleng ea khale." "E ne e se li-drive tsa 'nete tse feto-fetohang. Re ile ra li nkela sebaka ka li-Drives tse 'ne tsa Danfoss VLT® HVAC tse tsamaisitseng 100 HP ho 460 volts mme tsa fana ka qalo e bonolo ea nnete.
Ho ea ka Gary Sechler, ho qala ha bonolo ho ile ha felisa ho senyeha ho hoholo ha likoloi - hape ho boloka matla. “Re buisana le lienjene tse kholo ho pompa metsi ka tankeng ea cushion ea lilithara tse 300 mokatong oa mashome a tšeletseng a metso e mene.

Empa kea tseba ka qalo e bonolo ho VLT® Drives, ho aha lipompo tsa motlakase e bile zero. ”
Monyetla o latelang oa retrofit o ile oa itlhahisa ka mor'a hore naha ea Pennsylvania e fetise molao (PA ACT 129) ka November 2008 o hlokang Likhamphani tsa Kabo ea Motlakase ho fokotsa tšebeliso ea motlakase le tlhokeho e phahameng. Ho arabela, Duquesne Light e fane ka lenaneo la phokotso bakeng sa likhoebo tse kenyang li-drive frequency drive ho nka sebaka sa theknoloji ea khale ea lebelo la koloi.
Sechler o re: “Re ile ra potlakela lenaneong lena. Re ne re tseba seo VLT® Drives e se entseng bakeng sa lipompo tsa rona tsa metsi tsa ka tlung. Kahoo ka 2010, re ile ra sheba hore na ba ka etsa eng bakeng sa li-motor tsa rona tse kholo tsa 200- ho isa ho 250-HP.

Sechler o re: "Ka 2009, tšebeliso ea rona ea motlakase e ne e le lihora tse limilione tse 65 tsa kilowatts." “Hona joale e theohetse ho li-kilowatt tse limilione tse 43.
