Uluhlu lolawulo lobushushu kwizixhobo zokupholisa amanzi kwimizi-mveliso yi-5-35 degree Celsus, kodwa i-chiller inokufikelela kwintsebenzo engcono kakhulu phakathi kwe-20-30 degree Celsius. Ukuba abasebenzisi bafuna ukuseta ubushushu bamanzi bube kwi-5 degree Celsius, umthamo wokupholisa wesixhobo sokupholisa amanzi kwimizi-mveliso kufuneka ube mkhulu kunomthwalo wobushushu wesixhobo oza kupholiswa.
Emva kophuhliso lweminyaka eli-17, siseka inkqubo yomgangatho wemveliso engqongqo kwaye sibonelela ngenkonzo esekwe kakuhle emva kokuthengisa. Sinikezela ngeemodeli ezingaphezulu kwama-90 zokuthomalalisa amanzi ezisemgangathweni kunye ne-120 yeemodeli zokupholisa amanzi ukuze ulungelelanise. Ngomthamo wokupholisa ukusuka kwi-0.6KW ukuya kwi-30KW, ii-chillers zethu zamanzi zisebenza ukupholisa imithombo ye-laser eyahlukeneyo, oomatshini bokulungisa i-laser, oomatshini be-CNC, izixhobo zonyango, izixhobo zelabhoratri njalo njalo.
