Ndi ambiri chubu laser kudula makina zopangidwa mu msika, ndi kovuta kwambiri kusankha yoyenera pakati pa opanga zonsezi, koma pali malangizo angapo chilengedwe kuti owerenga akhoza kukumbukira. Mulingo wopangira, mtundu wazinthu komanso ntchito yogulitsa pambuyo pogulitsa ya wopanga zonse ziyenera kuganiziridwa. Ponena za chowonjezera chake chofunikira kwambiri -- recirculating water chiller , tikuyenera kusankha S&A Teyu yomwe ili ndi zaka 17 zakuchita firiji ndi mitundu ingapo yamakina oziziritsa madzi omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana.
Pankhani yopanga, S&A Teyu adayika zida zopangira yuan yopitilira miliyoni imodzi, kuwonetsetsa kuti njira zingapo zimachokera kuzinthu zazikuluzikulu (condenser) za mafakitale oziziritsa kukhosi mpaka kuwotcherera kwachitsulo; ponena za mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, atachepetsa kwambiri kuwonongeka chifukwa cha mayendedwe akutali a katunduyo, komanso kuwongolera magwiridwe antchito; pankhani ya pambuyo-malonda utumiki, nthawi chitsimikizo ndi zaka ziwiri.
