Mayiko aku Europe ali ndi malamulo okhwima okhudza mafiriji oziziritsa madzi oziziritsa mpweya. Chimodzi mwa zofunikira ndikugwiritsa ntchito firiji yosawononga chilengedwe. R407C ndi ya firiji yosawononga chilengedwe. Yokhala ndi R407C refrigerant yosawononga chilengedwe ndipo yokhala ndi chilolezo cha CE, ROHS, REACHE, mafiriji oziziritsa madzi oziziritsa mpweya a S&A Teyu amatha kutumizidwa kumayiko aku Europe.
Ponena za kupanga, S&A Teyu yayika zida zopangira zopitilira yuan miliyoni imodzi, kuonetsetsa kuti njira zosiyanasiyana zikuyenda bwino kuyambira pazigawo zazikulu (condenser) za chiller cha mafakitale mpaka kulumikiza zitsulo; pankhani ya mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, zomwe zachepetsa kwambiri kuwonongeka komwe kumachitika chifukwa cha mayendedwe ataliatali a katundu, komanso kukonza bwino mayendedwe; pankhani ya ntchito yogulitsa pambuyo pogulitsa, nthawi ya chitsimikizo ndi zaka ziwiri.
