Nthawi zambiri zimachitika kuti madzi ozungulira omwe ali mu chitofu cha madzi amaundana chifukwa cha kutentha kochepa m'nyengo yozizira, zomwe zimalepheretsa chitofu cha madzi kugwira ntchito bwino. Pothetsa vutoli, ogwiritsa ntchito amatha kuwonjezera chotsukira madzi mu chitofu cha madzi potsatira njira zotsatirazi:
1. Onjezani madzi ofunda kuti musungunule ayezi mumsewu wozungulira madzi;2. Akasungunuka ayezi, onjezerani chotsukira mufiriji molingana ndi momwe amafunira.
Komabe, dziwani kuti chotsukira madzi sichingagwiritsidwe ntchito kwa nthawi yayitali, chifukwa chimatha kuwononga chotsukira madzi mkati mwake chifukwa cha dzimbiri lake. Chifukwa chake, nyengo ikayamba kutentha ndipo madzi sakuundana, tikukulangizani kuchotsa madzi ozungulira ndi chotsukira madzi ndikudzazanso madzi oyeretsedwa kapena madzi osungunuka.
Ponena za kupanga, S&A Teyu yayika zida zopangira zopitilira yuan miliyoni imodzi, kuonetsetsa kuti njira zosiyanasiyana zikuyenda bwino kuyambira pazigawo zazikulu (condenser) za chiller cha mafakitale mpaka kulumikiza zitsulo; pankhani ya mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, zomwe zachepetsa kwambiri kuwonongeka komwe kumachitika chifukwa cha mayendedwe ataliatali a katundu, komanso kukonza bwino mayendedwe; pankhani ya ntchito yogulitsa pambuyo pogulitsa, nthawi ya chitsimikizo ndi zaka ziwiri.
