Rau kaw lub voj dej chiller uas txias tshuab dabtsi yog khoov, nws tau pom zoo kom siv ib puag ncig tus phooj ywg refrigerant kom tsis txhob ua rau huab cua puas. Tsis tas li ntawd, ntau lub teb chaws tsim kho twb tau txwv tsis pub cov tub yees tsis zoo ib puag ncig. Txhawm rau tiv thaiv ib puag ncig, S&Lub Teyu kaw voj dej chiller yog loaded nrog ib puag ncig tus phooj ywg refrigerant.
Hais txog kev tsim khoom, S&A Teyu tau nqis peev cov cuab yeej tsim khoom ntau dua li ib lab yuan, ua kom ntseeg tau qhov zoo ntawm cov txheej txheem los ntawm cov khoom tseem ceeb (condenser) ntawm cov tshuab chiller mus rau vuam ntawm cov ntawv hlau; Nyob rau hauv kev hwm ntawm logistics, S&A Teyu tau teeb tsa logistics warehouses nyob rau hauv lub nroog loj ntawm Tuam Tshoj, tau txo qis kev puas tsuaj vim kev thauj mus los ntev ntawm cov khoom, thiab txhim kho kev thauj mus los; Hauv kev hwm ntawm kev pabcuam tomqab muag, lub sijhawm lav yog ob xyoos.
