Kuyendetsa komwe kungachepetse liwiro la mpope ndi 20 peresenti kumabweretsa kupulumutsa mphamvu mpaka 50 peresenti.
Mu 2011, Sechler adayamba Gawo Lachiwiri la ntchito yobwezeretsanso. Apanso, Magalimoto a VLT® adagwiritsidwa ntchito popopera ma motors - koma nthawi ino kwa madzi ozizira komanso malupu amadzi asanayambe kutentha.
"Ma injini apampopewa ndi ang'ono kwambiri kuposa omwe amagwiritsidwa ntchito popanga madzi apanyumba," akutero Sechler. "Koma pali enanso aiwo." Pantchitoyi, Magalimoto a VLT® adagwiritsidwa ntchito pamapampu 40 kuyambira 50 HP mpaka 200 HP. Ndipo kachiwiri, ndalamazo zinali zodabwitsa: ndalama zamagetsi zapachaka zidachepetsedwanso $ 138,000.
Mu 2012, pulojekiti ya Gawo Lachitatu idawonjezera ma drive 16 a ma motors 250-HP. Kutsatira kukulitsa kwa zaka zitatu kwa PA ACT 129, Gawo Lachinayi la polojekitiyi mu 2013 idagwiritsa ntchito ma Drives pafupifupi 40 a VLT® kumapampu ang'onoang'ono a 7.5- mpaka 60-HP ndi ma fan motors. Pambuyo pa gawo lililonse, ndalama zosungira magetsi zidakwana $317,000 ndi $152,000 pachaka, motsatana.
Zotsatira zomwe zimakhudza gawo lotsika komanso mbiri
"Mu 2009, timagwiritsa ntchito magetsi okwana ma kilowatts 65 miliyoni," akutero Sechler. "Tsopano atsika mpaka 43 miliyoni kilowatts. Kufuna kwathu kwakukulu kunali ma megawati 16 mpaka 17; tsopano ndi 10 megawatts. Izi ndizosunga zazikulu zomwe zimapita mpaka kumapeto. Zonsezi, pafupifupi 150 Danfoss VLT® Drives ikupanga ndalama zoposa $ 1.1 miliyoni muzolembedwa zosungira mphamvu zamagetsi pachaka. Kuphatikiza apo, kukhathamiritsa kwamphamvu kwamagetsi kumapangitsa kuti nyumbayo ikhale yowoneka bwino kwa obwereketsa. Takhala anthu ofika pa 98 peresenti, zomwe ndi zabwino kwambiri pamsika wamakono wamalonda.
Kuwongolera kuyikako, drive iliyonse imaphatikiza Apogee® FLN ngati pulogalamu yosankha yolumikizana ndi pulogalamu yomwe imalumikizana ndi building automation system (BAS). Mayendetsedwe a pampu amawongoleredwa kudzera pa Direct Digital Control yamkati, yomwe imayesa kusiyanasiyana kwapampu kuti iwongolere kuthamanga kwagalimoto. Zolemba za BAS zimayendetsa magwiridwe antchito komanso kugwiritsa ntchito mphamvu, kuphatikiza mawonekedwe agalimoto. Gulu la mainjiniya a Sechler limathanso kutsata momwe amagwirira ntchito - ndipo ali okondwa kuti sipanakhalepo nthawi yopumira kuyambira pomwe yoyamba idakhazikitsidwa zaka 15 zapitazo.
Malinga ndi a Danfoss Sales Manager a Stanley Aranowski, kupitilizabe bwino kwa zobwezeredwazi ndi mwayi kwa SSI, Inc., Danfoss yemwe amagwira nawo ntchito ku Cranberry Township, Pa.
