Njengoko sonke sisazi, yonke into ethunyelwa kumazwe aseYurophu kufuneka ihlangabezane neemfuno ezininzi. Enye yeemfuno kukusebenza kokusingqongileyo. Kumatshini wokupholisa amanzi opholileyo, oko kuthetha ukuba ifriji eyisebenzisayo kufuneka ikhuseleke ngokusingqongileyo. I-R407C yeyefriji ehambelana nokusingqongileyo. Ihlawuliswe nge-R407C yesibandisi esivumelana nokusingqongileyo kunye ne-CE, ROHS, imvume yokuFINYELELA, S&A Oomatshini baseTeyu abapholisa umoya bayakwazi ukuthunyelwa kumazwe aseYurophu.
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.
