Lapho umshini wokusika izinkuni we-CO2 laser usebenza, ukugeleza kwamanzi okubushelelezi kwe-chiller yamanzi yezimboni kufanele kuqinisekiswe, ngoba amanzi okupholisa ukususa ukushisa eshubhu le-laser. Lapho izinga lokushisa lamanzi liphakeme le-chiller yamanzi yezimboni, amandla aphansi okukhipha ishubhu ye-laser ye-CO2 azoba. Uma kungekho ukugeleza kwamanzi, ukuqhuma kweshubhu le-laser kungenzeka ngenxa yokushisa ngokweqile noma amandla kagesi e-laser azolimala. Kulokhu, singabona ukuthi i-chiller yamanzi yezimboni idlala indima ebalulekile ekupholiseni i-CO2 laser ukuze ukusebenza kahle komshini wokusika izinkuni we-CO2 laser kuqinisekiswe.
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.
