Ngokuvamile akunanto yakwenza nesiqandisi samanzi sezimboni uma sine-voltage engazinzile. Kungenzeka ukuthi ibangelwa yi-voltage enikeziwe. Ngakho-ke, kunconywa ukufaka isiqinisi se-voltage futhi ugweme ukuthi isiqandisi sisebenze isikhathi eside ngaphansi kwe-voltage engazinzile, ngoba lokhu kungabangela ukungasebenzi kahle ngaphakathi kwesiqandisi samanzi sezimboni noma kushise iphampu yamanzi ngaphakathi.
Ngokuphathelene nokukhiqiza, i-S&A Teyu itshale imishini yokukhiqiza engaphezu kwesigidi sama-yuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-industrial chiller kuya ekushiseni insimbi; ngokuphathelene nokuthutha, i-S&A Teyu isungule izindawo zokugcina impahla emadolobheni amakhulu aseShayina, njengoba inciphise kakhulu umonakalo obangelwa ukuthutha impahla ibanga elide, futhi ithuthukise ukusebenza kahle kwezokuthutha; ngokuphathelene nensizakalo yangemva kokuthengisa, isikhathi sewaranti siyiminyaka emibili.
