Ukuze kukhuselwe okusingqongileyo, uS&Iyunithi yokupholisa amanzi yaseTeyu ihlawuliswa iifriji ezinobuhlobo bokusingqongileyo, kuquka i-R-410a, i-R-407C kunye ne-R-134a. Nangona kunjalo, ekuthuthweni kwemoya, ifriji kufuneka ikhutshwe, kuba ifriji iyaqhuma kwaye iyatsha kwaye iyanqatshelwa ekuthuthweni komoya. Ngoko ke, xa abasebenzisi befumana iyunithi yokupholisa amanzi, kufuneka ukuba i-chiller iphinde ifakwe kwifriji echazwe kwindawo yenkonzo ye-air conditioner yendawo.
Ngokubhekiselele kwimveliso, uS&I-Teyu ityale imali kwizixhobo zemveliso ezingaphezulu kwesigidi seeyuan, iqinisekisa umgangatho woluhlu lweenkqubo ukusuka kumacandelo angundoqo (i-condenser) ye-industrial chiller ukuya kwiwelding ye sheet metal; ngokumalunga nolungiselelo, S&I-Teyu imise iindawo zokugcina iimpahla kwiidolophu eziphambili zaseChina, zinciphise kakhulu umonakalo ngenxa yokuhanjiswa kwexesha elide lempahla, kunye nokuphucula ukusebenza kakuhle kwezothutho; ngokumalunga nenkonzo emva kokuthengisa, ixesha lewaranti yiminyaka emibini.
