Hoʻohana pinepine ʻia ka ʻāpana wai chiller i ka hoʻoluʻu ʻana i ka hāmeʻa laser a me ke poʻo ʻoki o ka mīkini ʻoki laser metala lahilahi. No laila he aha ka pōmaikaʻi o ka hoʻonohonoho ʻana i ka mahana wai o 30℃ ma Vietnam? Wahi a ka ʻike a S&ʻO kahi hui chiller wai Teyu, hiki ke hana maikaʻi ka ʻāpana wai chiller i ka wā o ka mahana i loko o ka laulā o 20℃~30℃.
E pili ana i ka hana, S&Ua hoʻokomo ʻo A Teyu i nā mea hana o ka ʻoi aku ma mua o hoʻokahi miliona RMB, e hōʻoiaʻiʻo ana i ka maikaʻi 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, pau nā S&Hoʻopaʻa ʻia kahi ʻeke wai ʻo Teyu e ka hui ʻinikua a ʻelua makahiki ka manawa hoʻopaʻa.
