Kwenzeka kakhulu ukuthi amanzi ajikelezayo ku-chiller yamanzi aba yiqhwa ngenxa yezinga lokushisa eliphansi ebusika, okuvimbela isibandisi samanzi singasebenzi ngendlela evamile. Ngokuxazulula le nkinga, abasebenzisi bangakwazi ukwengeza isiqandisi kwisiqandisi samanzi ngokulandela izinyathelo ezingezansi:
1. Faka amanzi afudumele ukuze uncibilikise iqhwa emgwaqeni wamanzi ojikelezayo;
2. Ngemva kokuba iqhwa liyancibilika, engeza i-anti-freezer ngokulingana.
Kodwa-ke, sicela uqaphele ukuthi i-anti-freezer ayikwazi’ingasetshenziswa isikhathi eside, njengoba ingalimaza isiqandisi samanzi ngaphakathi ngenxa yokugqwala kwayo. Ngakho-ke, lapho isimo sezulu siqala ukufudumala futhi namanzi ’t, kuphakanyiswa ukuthi kukhishwe amanzi ajikelezayo nge-anti-freezer futhi uphinde ugcwalise amanzi ahlanzekile noma amanzi acwecwe.
Mayelana nokukhiqizwa, u-S&I-Teyu itshale amathuluzi okukhiqiza amayuan angaphezu kwesigidi, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-chiller yezimboni kuya ekushiseleni kweshidi lensimbi; mayelana ne-logistics, S&I-Teyu imise izindawo zokugcina izimpahla emadolobheni amakhulu aseShayina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwezimpahla ezikude, kanye nokwenza ngcono ukusebenza kahle kwezokuthutha; mayelana nesevisi yangemuva kokuthengisa, isikhathi sewaranti iminyaka emibili.
