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, uS&I-Teyu ityale imali kwizixhobo zemveliso ezingaphezulu kwesigidi seeyuan, iqinisekisa umgangatho woluhlu lweenkqubo ukusuka kumacandelo angundoqo (i-condenser) ye-industrial chiller ukuya kwiwelding ye sheet metal; ngokumalunga nolungiselelo, S&I-Teyu imise iindawo zokugcina iimpahla kwiidolophu eziphambili zaseChina, zinciphise kakhulu umonakalo ngenxa yokuhanjiswa kwexesha elide lempahla, kunye nokuphucula ukusebenza kakuhle kwezothutho; ngokumalunga nenkonzo emva kokuthengisa, ixesha lewaranti yiminyaka emibini.
