Ngokuthuthukiswa kobuchwepheshe be-laser, isisekeli sayo esibalulekile- isikhilimu samanzi sezimboni- siyachuma futhi baningi impela abakhiqizi bezimboni zokupholisa amanzi eChina. Kubandakanya i-S&A Teyu, Doluyo, Tongfei kanye ne-Hanli. Abakhiqizi abahlukene banezinzuzo ezahlukene. Thatha i-S&A Teyu njengesibonelo. S&A Imishini ye-Teyu yokupholisa amanzi inikeza amamodeli amaningi okukhethwayo kanye nesevisi esheshayo yangemva kokuthengisa kanye newaranti yeminyaka emi-2. Abasebenzisi bangenza isinqumo sokuthenga ngokusekelwe ezidingweni zabo.
Mayelana nokukhiqiza, S&A I-Teyu itshale impahla yokukhiqiza ye-RMB engaphezu kwesigidi, 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, wonke ama- S&A ama-water chiller e-Teyu angaphansi kwenkampani yomshwalense futhi isikhathi sewaranti iminyaka emibili.
