Ngaphambi kokuba umshini wokucwenga amanzi we-aluminium laser uphume efektri, amanzi ajikelezayo ayakhishwa ukuze kube lula ukuthutha. Lapho abasebenzisi bethola umshini wokucwenga amanzi futhi bewufake, kudingeka bagcwalise iyunithi yokucwenga amanzi ngamanzi ahlanzekile. Qaphela: akuvunyelwe ukusebenzisa iyunithi yokucwenga amanzi ngaphandle kwamanzi futhi sicela ungeze amanzi enkombeni eluhlaza yegeyiji yezinga lamanzi.
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.
