Refrigerant ndi njira yopangira firiji mufiriji yochokera ku mafakitale oziziritsa madzi ozizira. Ngati pali zosakwanira refrigerant mu mafakitale madzi kuzirala chiller, ndi chiller sangathe refrigerate bwino. Pachifukwa ichi, ogwiritsa ntchito akulangizidwa kuti awonjezerenso ndi refrigerant yokwanira yamtundu womwewo ndi kuchuluka koyenera komwe kukuwonetsedwa mu parameter.
Pambuyo pa chitukuko cha zaka 18, timakhazikitsa dongosolo lokhazikika lazogulitsa ndikupereka ntchito yokhazikika pambuyo pa malonda. Timapereka mitundu yopitilira 90 yotenthetsera madzi ndi mitundu 120 yoziziritsa madzi kuti musinthe mwamakonda anu. Ndi mphamvu kuzirala kuyambira 0.6KW kuti 30KW, madzi chillers athu ntchito kuziziritsa magwero osiyanasiyana laser, makina processing laser, makina CNC, zida zachipatala, zipangizo zasayansi ndi zina zotero.
