Malinga ndi zomwe S&A Teyu yakumana nazo, sikulangizidwa kusankha refrigerant mwachisawawa ndikuiyika mu refrigerant choziziritsira chomwe chimaziziritsa makina odulira nsalu ndi laser. Refrigerant yatsopanoyo iyenera kukhala yofanana ndi yoyamba. Apo ayi, compressor ya refrigerant choziziritsira idzawonongeka. Akuti ogwiritsa ntchito afunseni ogulitsa chiller kuti adziwe mtundu ndi kuchuluka kwa refrigerant kuti refrigerant igwire ntchito bwino pakapita nthawi.
Pambuyo pa zaka 18, timakhazikitsa njira yolimba yopangira zinthu ndikupereka ntchito yabwino yogulitsa pambuyo pogulitsa. Timapereka mitundu yoposa 90 ya ma water chiller ndi mitundu 120 ya ma water chiller kuti tisinthe. Popeza mphamvu yathu yozizira ndi kuyambira 0.6KW mpaka 30KW, ma water chiller athu amagwiritsidwa ntchito poziziritsa magwero osiyanasiyana a laser, makina opangira laser, makina a CNC, zida zachipatala, zida za labotale ndi zina zotero.
