Ukuze kukhuselwe indalo esingqongileyo, S&A Iyunithi yokupholisa amanzi yaseTeyu ihlawuliswa izikhenkcezisi ezilungele ukusingqongileyo, kuquka i-R-410a, i-R-407C kunye ne-R-134a. Nangona kunjalo, ekuthuthweni kwemoya, ifriji kufuneka ikhutshwe, kuba ifriji iyaqhuma kwaye iyatsha kwaye inqatshelwe 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, S&A iTeyu ityale imali kwizixhobo zemveliso ezingaphezulu kwesigidi seeyuan, iqinisekisa umgangatho woluhlu lweenkqubo ukusuka kumacandelo angundoqo (condenser) we-industrial chiller ukuya kwiwelding ye sheet metal; ngokubhekiselele kumalungiselelo, S&A I-Teyu imise iindawo zokugcina iimpahla kwiidolophu eziphambili zaseChina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwempahla ekude, kunye nokuphucula ukusebenza kakuhle kwezothutho; ngokumalunga nenkonzo emva kokuthengisa, ixesha lewaranti yiminyaka emibini.
