Njengoba kunezinhlobo eziningi kangaka zemishini yokusika i-laser yamashubhu emakethe, kunzima kakhulu ukukhetha efanele phakathi kwabo bonke laba bakhiqizi, kodwa kuneziqondiso ezimbalwa ezijwayelekile abasebenzisi abangazikhumbula. Isikali sokukhiqiza, ikhwalithi yomkhiqizo kanye nensizakalo yangemva kokuthengisa yomkhiqizi kufanele kucatshangelwe. Ngokuphathelene nesesekeli sayo esibalulekile -- ukujikeleza kabusha i-water chiller, kuphakanyiswa ukukhetha i-S&A Teyu enolwazi lweminyaka engu-17 lokuqandisa kanye namamodeli amaningi emishini yokushisa amanzi esebenza ezimbonini ezahlukene.
Ngokuphathelene nokukhiqiza, i-S&A Teyu itshale imishini yokukhiqiza engaphezu kwesigidi sama-yuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-industrial chiller kuya ekushiseni insimbi; ngokuphathelene nokuthutha, i-S&A Teyu isungule izindawo zokugcina impahla emadolobheni amakhulu aseShayina, njengoba inciphise kakhulu umonakalo obangelwa ukuthutha impahla ibanga elide, futhi ithuthukise ukusebenza kahle kwezokuthutha; ngokuphathelene nensizakalo yangemva kokuthengisa, isikhathi sewaranti siyiminyaka emibili.
