Malinga ndi zomwe S&A Teyu adakumana nazo, zotsatirazi ndi zomwe zingayambitse:
1. Kudziyeretsa kwa makina oziziritsira madzi a mafakitale sikwabwino ndipo mwina kumachitika chifukwa cha kusowa bwino kwa mafani ozizira, vuto lalikulu la fumbi komanso kutentha kwambiri;2. Dongosolo la makina oziziritsira madzi a m'mafakitale silikugwira ntchito momwe limafunikira. Mwachitsanzo, mphamvu yolowera siikugwirizana; firiji yomwe imagwiritsidwa ntchito siikugwirizana; palibe kuyeretsa pafupipafupi pa condenser ndi fumbi gauze ndi zina zotero. Zonsezi zitha kupangitsa kuti makina oziziritsira madzi a m'mafakitale asamagwire bwino ntchito.
Pofuna kupewa kugwiritsa ntchito bwino firiji, tikukulangizani kuti muzisamalira makina oziziritsira madzi a m'mafakitale nthawi zonse.
Pambuyo pa zaka 17, 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.
