Xa uthelekisa i-chiller yamanzi, S&A I-Teyu ihlala icela abathengi ukuba babonelele oko kusetyenziselwa ukupholisa, kwaye yintoni amandla kunye nesantya sokuhamba kweso sixhobo, ukwenzela ukuba ifanise uhlobo oluchanekileyo. Nangona kunjalo, abanye abathengi banokukhetha uhlobo ngokwabo ukubhengezwa kolwazi olungathandekiyo. Emva koko le meko ilandelayo inokwenzeka:
UMnu. Chen, umthengi we-laser, obizwa ngokuba S&A Teyu ukuba ulondolozo lwalufuneka kwi-CW-5200 ye-chiller yamanzi ngenxa yokungasebenzi kakuhle. Bekusaziwa ngonxibelelwano ukuba izixhobo zelaser eziza kupholiswa kufuneka zixhaswe yi-chiller yamanzi ene-2700W yokupholisa umthamo kunye nokuphakama kwe-21m, ngoko ke i-CW-5200 ene-1400W yokupholisa yayingafanelekanga. Kamva, waqinisekisa ukuba i-100W RF ityhubhu yensimbi yayisetyenziswa. Ngoko ke, sicebise i-CW-6000 ye-chiller yamanzi kunye ne-3000W umthamo wokupholisa, kwaye wabeka umyalelo ngokukhawuleza. Ukongeza, wancoma kakhulu ubungcali be S&A Teyu ekukhetheni uhlobo lwe-chiller yamanzi.
