Isikhenkcezisi sidlala indima ebalulekileyo kwinkqubo yefriji yokubuyisela kwakhona i-chiller yamanzi. Ifriji yangoku elungele indalo iquka i-R134A, i-R410A kunye ne-R407C. Ukuba abasebenzisi banemfuno ekhethekileyo malunga nefriji, banokunxibelelana nomthengisi we-chiller ngokufanelekileyo.
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.
