Recirculating laser chiller amagwiritsidwa ntchito pochotsa kutentha kwa magwero a laser a zida za laser. Amagwiritsa ntchito kayendedwe ka madzi kosalekeza kwa kutengerapo kutentha ndi dongosolo la firiji mkati mwa laser madzi chiller adzaziziritsa madzi otentha ndiyeno utakhazikika pansi madzi ndiye kuthamanga kubwerera ku magwero laser, kuyamba kuzungulira kwina kutentha kusamutsa. Njira yopitilira iyi imatsimikizira kuti magwero a laser amatha kukhala pansi pa kutentha koyenera.
Pambuyo pa chitukuko cha zaka 19, 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.
