U-R22 akusona isiqandisi semvelo, ngakho-ke i-water chiller esebenzisa u-R22 ayikwazi ukuthunyelwa emazweni aseYurophu. Ngakho-ke, isiqandisi semvelo sithandwa kakhulu ekuthunyelweni kwe-water chiller. Ukuze S&A I-Teyu spindle water chiller, amafriji emvelo afana no-R134A, R410A kanye no-R407C ayatholakala, ukuze ungakhathazeki ngodaba lokuthunyelwa kwempahla kwamanye amazwe.
Mayelana nokukhiqiza, S&A I-Teyu itshale impahla yokukhiqiza ye-RMB engaphezu kwesigidi, 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, wonke ama- S&A ama-Chillers amanzi e-Teyu amboza Umshwalense Wesibopho Somkhiqizo kanye nesikhathi sewaranti yomkhiqizo iminyaka emibili.
