Njengoko sonke sisazi, yonke into ethunyelwa kumazwe aseYurophu kufuneka ihlangabezane neemfuno ezininzi. Enye yeemfuno kukusebenza kokusingqongileyo. Emoyeni opholileyo kumatshini wokupholisa amanzi, oko kuthetha ifriji iyayisebenzisa kufuneka ihambelane nokusingqongileyo. I-R407C yeyefriji ehambelana nokusingqongileyo. Ihlawuliswe nge-R407C ifriji ehambelana nokusingqongileyo kunye ne-CE, ROHS, imvume yokuFINYELELA, S.&A Teyu umoya opholileyo chiller oomatshini bayakwazi ukuthunyelwa kumazwe aseYurophu
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.
