Njengoba sonke sazi, konke okuthunyelwa emazweni aseYurophu kumele kuhlangabezane nezidingo eziningi. Esinye sezimfuneko ukuba nobungane nemvelo emvelweni. Emshinini wokupholisha amanzi opholile emoyeni, lokho kusho ukuthi isiqandisi esisetshenziswayo kumele sibe nobungane nemvelo. I-R407C ingeyesiqandisi esinobungane nemvelo. Ikhokhiswa nge-R407C yesiqandisi esinobungane nemvelo futhi ngokuvunyelwa yi-CE, ROHS, REACHE, imishini yokupholisha amanzi epholile emoyeni ye-S&A Teyu iyakwazi ukuthunyelwa emazweni aseYurophu.
Ngokuphathelene nokukhiqiza, i-S&A Teyu itshale imishini yokukhiqiza engaphezu kwesigidi sama-yuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-industrial chiller kuya ekushiseni insimbi; ngokuphathelene nokuthutha, i-S&A Teyu isungule izindawo zokugcina impahla emadolobheni amakhulu aseShayina, njengoba inciphise kakhulu umonakalo obangelwa ukuthutha impahla ibanga elide, futhi ithuthukise ukusebenza kahle kwezokuthutha; ngokuphathelene nensizakalo yangemva kokuthengisa, isikhathi sewaranti siyiminyaka emibili.
