Nokho, amamodeli ahlukene amayunithi okushisa amanzi abandayo e-S&A Teyu anezidingo ezahlukene ekushiseni okuzungezile.
Kwiyunithi yokupholisa amanzi abandayo ye-S&A Teyu CW-3000, i-alamu yokushisa okuphezulu kwegumbi izovulwa lapho izinga lokushisa elizungezile lingaphezu kwama-degree Celsius angu-60. Kwiyunithi yokupholisa amanzi abandayo ye-S&A Teyu CW-5000 nangaphezulu, i-alamu izovulwa lapho izinga lokushisa elizungezile lingaphezu kwama-degree Celsius angu-50. Kunconywa ukuthi amayunithi okupholisa amanzi abandayo afakwe endaweni enomoya omuhle.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.
