Kuvamile ukuthi umshini wokumaka we-laser we-PCB ophinda ujikeleze iyunithi yokupholisa amanzi wenze umsindo omncane lapho usebenza futhi lowo msindo ngokuvamile wenziwa ifeni yokupholisa noma ezinye izingxenye. Kodwa-ke, uma umsindo umkhulu kakhulu, abasebenzisi kudingeka bahlole ukuthi i-recirculating water chiller ifakwe kahle yini noma uma kukhona okungalungile ngezingxenye.
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.
