Zogulitsa za arex ndizosasinthika mu gawo la mafakitale. Zogulitsa zathu nthawi zambiri zimawonetsedwa ngati zida zazikulu kapena zida zazing'ono zomwe zidaphatikizidwa mu ntchito yamakampani kapena njira zambiri zowonjezera zamagulu kapena zinthu zina zomwe zimagwira ntchito yofunikira pakuchita zida kapena dongosolo. Monga ma valves osiyanasiyana, kapena zida zamagetsi zomwe zikuchitika. Kugwiritsa ntchito mapangidwe a mphira ndi zopangidwa ndi pulasitiki, kuphatikiza ndi malo omwe amagwiritsidwa ntchito, kampani ya ARX isintha zinthu zake kukhala zabwino kwambiri, kuchepetsa mitundu kapena opaleshoniyo imatha kuwoneka pachiwopsezo, moyo wautumiki. Makhalidwe ake amawonetsedwa makamaka pakuteteza zitsulo za zida kapena dongosolo, zotsutsana ndi zopopera pulasitiki ndi acid. Makina ndi zida zomwe zimagwiritsidwa ntchito ndi Asral zimatha kusintha ndikupangidwira pazopempha, ndipo mayankho ofunikira atha kuperekedwa kwa makasitomala omwe ali ndi vuto laling'ono. Mothandizidwa ndi ntchito yolemera, kuphatikizana ndi kukhazikitsa kwenikweni kwa nkhaniyi, gulu lathu laukadaulo ndi gulu lathu lopanga liziika patsogolo, sinthani makasitomala popanga zotayika zosafunikira.
