Kuzizira kozizira, komwe kumayezedwa ndi KW kapena P, ndi zotsatira za kuwerengera kwina kutengera mfundo yozizirira ya chiller yamadzi. Kwa S&A Teyu CW-6000 wozizira madzi, mphamvu yozizirira ndi 3KW. Chonde dziwani kuti kuziziritsa kwa chiller kuyenera kugwirizana ndi kuziziritsa zofunikira za zida pankhani yosankha madzi oziziritsa.
Pankhani yopanga, S&A Teyu adayika zida zopangira yuan yopitilira miliyoni imodzi, kuwonetsetsa kuti njira zingapo zimachokera kuzinthu zazikuluzikulu (condenser) za mafakitale oziziritsa kukhosi mpaka kuwotcherera kwachitsulo; ponena za mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, atachepetsa kwambiri kuwonongeka chifukwa cha mayendedwe akutali a katunduyo, komanso kuwongolera magwiridwe antchito; pankhani ya pambuyo-malonda utumiki, nthawi chitsimikizo ndi zaka ziwiri.
