Njengoba kunemikhiqizo eminingi yomshini wokusika we-laser emakethe, kunzima kakhulu ukukhetha okulungile phakathi kwabo bonke laba bakhiqizi, kodwa kuneziqondiso ezimbalwa zendawo yonke abasebenzisi abangazikhumbula. Isilinganiso sokukhiqiza, ikhwalithi yomkhiqizo kanye nesevisi yangemuva kokuthengisa yomkhiqizi konke kufanele kucatshangelwe. Ngokuqondene nesesekeli sayo esibalulekile -- recirculating water chiller , kuphakanyiswa ukuthi ukhethe i-S&A Teyu enolwazi lwesiqandisi seminyaka engu-17 kanye namamodeli emishini eminingi yokuthobisa amanzi asebenza ezimbonini ezihlukahlukene.
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.
