Nokho, amamodeli ahlukene S&A amayunithi okupholisa amanzi abandayo e-Teyu anezidingo ezihlukene kuzinga lokushisa elizungezile.
Ku-S&A Iyunithi yokupholisa amanzi abandayo ye-Teyu CW-3000, i-alamu yezinga lokushisa eliphezulu izocushwa uma izinga lokushisa le-ambient lingaphezu kuka-60 degrees Celsius. Ku-S&A Iyunithi yokupholisa amanzi abandayo ye-Teyu CW-5000 nangaphezulu, i-alamu izocushwa uma izinga lokushisa le-ambient lingaphezu kuka-50 degrees Celsius. Kunconywa ukubeka amayunithi okupholisa amanzi abandayo endaweni enomoya omuhle.Mayelana nokukhiqizwa, i- S&A I-Teyu itshale izimali zokukhiqiza ezingaphezu kwesigidi samayuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-chiller yezimboni kuya ekushiseleni kweshidi lensimbi; ngokuphathelene nempahla, S&A I-Teyu imise izindawo zokugcina izimpahla emadolobheni amakhulu aseShayina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwezimpahla ezikude, kanye nokusebenza kahle kwezokuthutha; mayelana nesevisi yangemuva kokuthengisa, isikhathi sewaranti iminyaka emibili.
