He mea maikaʻi e hoʻolako i ka recirculating chiller chiller unit me nā kānana, no ka mea hiki iā ia ke kānana i nā haumia i loko o ka wai kaʻapuni e hōʻoia i ka maʻemaʻe o ka wai. ʻElua ʻano maʻamau o nā mea kānana: PP cotton filter element a me wire-wound filter element. E hāʻule ka mea kānana pulupulu PP i ka pulupulu pulupulu ma hope o ka lōʻihi o ka hoʻohana ʻana a ʻo ka hāʻule ʻana o ka pulupulu pulupulu e hoʻopuʻi ai i ka wā e lanakila ai ka mea kānana uea-ʻeha’t. S&Hoʻolako ʻia kahi ʻāpana hoʻoheheʻe ʻenehana Teyu recirculating me ka mea kānana uea-ʻeha pae ʻoihana ʻaʻole e wehe a loaʻa ka hana kānana maikaʻi.
E pili ana i ka hana, S&Ua hoʻolilo ʻo A Teyu i nā lako hana ʻoi aku ma mua o hoʻokahi miliona yuan, e hōʻoiaʻiʻo ana i ka maikaʻi o ke ʻano o nā kaʻina hana mai nā ʻāpana kumu (condenser) o ka chiller ʻoihana a hiki i ke kuʻi ʻana o ka metala; e pili ana i ka logistics, S&Ua hoʻonohonoho ʻo A Teyu i nā hale kūʻai logistic ma nā kūlanakauhale nui o Kina, me ka hoʻohaʻahaʻa nui ʻana i ka pōʻino ma muli o ka logistic lōʻihi o nā waiwai, a me ka hoʻomaikaʻi ʻana i ka lawe ʻana; e pili ana i ka lawelawe ma hope o ke kūʻai aku, ʻelua makahiki ka manawa hoʻohiki.
