Pamene palibe refrigerant mu woonda zitsulo CHIKWANGWANI laser wodula mpweya utakhazikika refrigeration chiller, pali mwayi wabwino kuti refrigerant kutayikira zimachitika kwa mpweya utakhazikika mufiriji chiller. Monga tikudziwira, kusowa kwa firiji kumalepheretsa chiller kuti chikhale mufiriji. Chifukwa chake, tikulimbikitsidwa kuti mupeze ndikuwotcherera pomwe pakutayikira ndikudzazanso ndi firiji yatsopano. Koma chonde kumbukirani kuti mtundu ndi kuchuluka kwa firiji ziyenera kukhala zofanana ndi zomwe zasonyezedwa pazigawo zozizira.
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 yotenthetsera 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.
