Ngezantsi ngamanqaku ekufuneka akhunjulwe xa ukhetha iyunithi ye-industrial chiller kumatshini wokuhlamba:
1.Umthamo wokupholisa weyunithi ye-industrial chiller kufuneka ihlangabezane nemfuneko yokupholisa yomatshini wokulambisa;2.Ukuhamba kwempompo kunye nokuphakanyiswa kwempompo kufuneka kwakhona kuhlangabezane nemfuneko;
3.Khetha umenzi we-chiller onemveliso ekumgangatho ophezulu kunye nenkonzo ekhawulezayo emva kokuthengisa.
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.
