Njengoba sonke sazi, yonke into ethunyelwa emazweni aseYurophu kumele ihlangabezane nezidingo eziningi. Enye yezidingo wukuba ne-eco-friendly emvelweni. Emshinini wokupholisa amanzi opholile, lokho kusho ukuthi isiqandisi esisisebenzisayo kufanele sihambisane nemvelo. I-R407C ingeyefriji ehambisana nemvelo. Ishajwa ngesiqandisi esivumelana nemvelo esingu-R407C kanye nemvume ye-CE, ROHS, REACHE, S&A Imishini ye-Teyu air cooled water chiller iyakwazi ukuthunyelwa emazweni aseYurophu.
Mayelana nokukhiqizwa, i- S&A I-Teyu itshale izimali zokukhiqiza ezingaphezu kwesigidi samayuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-chiller yezimboni kuya ekushiseleni kweshidi lensimbi; ngokuphathelene nempahla, S&A I-Teyu imise izindawo zokugcina izimpahla emadolobheni amakhulu aseShayina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwezimpahla ezikude, kanye nokusebenza kahle kwezokuthutha; mayelana nesevisi yangemuva kokuthengisa, isikhathi sewaranti iminyaka emibili.
