Ukuze kuvikelwe imvelo, iyunithi yokupholisa amanzi ye-S&A Teyu ineziqandisi ezinobungani nemvelo, okuhlanganisa i-R-410a, i-R-407C kanye ne-R-134a. Kodwa-ke, ekuthuthweni emoyeni, isiqandisi sidinga ukukhishelwa ngaphandle, ngoba isiqandisi siyaqhuma futhi siyasha futhi asivunyelwe ekuthuthweni emoyeni. Ngakho-ke, lapho abasebenzisi bethola iyunithi yokupholisa amanzi, badinga ukuthi isiqandisi sigcwaliswe ngesiqandisi esichazwe endaweni yesevisi yendawo yokupholisa umoya.
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.
