Ngokubanzi, ifeni yesikhenkcisi samanzi iyayeka ukusebenza (oko kukuthi ifeni ayijiki) inokubangelwa zezi zizathu zilandelayo:
1. Isekethe yefeni inxibelelana kakubi okanye iyakhululeka. Isisombululo: Jonga isekethe ngokufanelekileyo.2. I-capacitance iyancipha. Isisombululo: Guqula esinye isakhono.
3. Ikhoyili iyatsha. Isisombululo: Yonke ifeni kufuneka itshintshwe.
Ukuba izixhobo zokupholisa amanzi ozithenge kwa- S&A kwa-Teyu banale ngxaki, ungaqhagamshelana neziko lenkonzo yokuthengisa emva kokuthengisa.
Ngokubhekiselele kwimveliso, S&A iTeyu ityale imali kwizixhobo zemveliso ezingaphezulu kwesigidi seeyuan, iqinisekisa umgangatho woluhlu lweenkqubo ukusuka kumacandelo angundoqo (condenser) we-industrial chiller ukuya kwiwelding ye sheet metal; ngokubhekiselele kumalungiselelo, S&A I-Teyu imise iindawo zokugcina iimpahla kwiidolophu eziphambili zaseChina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwempahla ekude, kunye nokuphucula ukusebenza kakuhle kwezothutho; ngokumalunga nenkonzo emva kokuthengisa, ixesha lewaranti yiminyaka emibini.
