M'kupita kwa nthawi, ndizosavuta kuti fumbi liwunjike pa makina ozungulira a mafakitale omwe amazizira FPCB laser cutter. Ngati vuto la fumbi silingathetsedwe, ntchito ya firiji ya mafakitale a laser cooling chiller unit ingakhudzidwe. Kuchotsa fumbi sikovuta. Ogwiritsa ayenera kutsegula fumbi yopyapyala mwa kukanikiza batani kumbali pepala zitsulo za recirculating mafakitale chiller dongosolo ndiyeno kuchotsa fumbi pa fumbi yopyapyala.
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.
