Ngati S&A Teyu mpweya wozizira wozizira wozizira CW-6000 utaphimbidwa ndi fumbi wandiweyani, kutentha kwake sikungathe kutayidwa bwino, kotero kuti zotsatira za firiji za mpweya woziziritsidwa wa firiji zidzakhudzidwa. Choncho, akulangizidwa kuchotsa fumbi panthawi yake. Bwanji? Chophweka njira ndi ntchito mpweya mfuti kuyeretsa condenser ndi fyuluta yopyapyala, amene angathe kusintha firiji zotsatira ndi kuwonjezera moyo ntchito firiji mpweya utakhazikika chiller.
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.
