Njengesisetshenziswa sokupholisa se-water chiller esipholisa umshini wokushisela imvamisa ephezulu, amanzi ajikelezayo iyisici esibalulekile. Ngakho-ke, kuphakanyiswa ukuthi kusetshenziswe amanzi ahlanzekile noma amanzi ahlanzekile acwengekile njengamanzi ajikelezayo futhi esikhundleni sawo ngezikhathi ezithile (njalo ezinyangeni ezi-3 kuyaphakanyiswa) ukuze kugwenywe ukuvaleka emgwaqeni wamanzi ojikelezayo ngenxa yokungcola nokugcina ukusebenza okuzinzile kokupholisa kwesibandisi samanzi.
Mayelana nokukhiqizwa, i- 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-Chillers amanzi e-Teyu amboza Umshwalense Wesibopho Somkhiqizo futhi isikhathi sewaranti iminyaka emibili.
