Refrigerant imatchedwanso Freon ndipo imatha kugawidwa m'magulu awiri: yosamalira zachilengedwe ndi yosasamalira zachilengedwe. Ndi malo ofunikira kwambiri oziziritsira makina oziziritsira a mafakitale omwe amaziziritsa makina olembera a laser a UV. Pofuna kuteteza bwino chilengedwe, mayunitsi onse a S&A Teyu amadzazidwa ndi refrigerant yosamalira zachilengedwe.
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.
