Iwaranti yenye yezona zinto zibalulekileyo ezichaphazela isigqibo sokuthenga sabathengi. Kubathengi, bakhetha ukubhenela kubaboneleli abanokubonelela ngewaranti ende. Ngokungafaniyo nabanye ababoneleli nge-laser chiller abanikezela ngewaranti yonyaka omnye kuphela okanye abangenayo kwaphela iwaranti, i-S&A Teyu inikezela ngewaranti yeminyaka emi-2 kwii-laser chillers ezipholileyo emoyeni kunye nenkonzo ephezulu emva kokuthengisa kunye nenkxaso. Ke ngoko, abathengi banokuqiniseka ngokusebenzisa ii-laser chillers ze-S&A Teyu ezijikelezayo.
Emva kweminyaka eli-19 yophuhliso, siseka inkqubo yomgangatho wemveliso engqongqo kwaye sinikezela ngenkonzo esemgangathweni emva kokuthengisa. Sinikezela ngeemodeli ezingaphezu kwama-90 ze-water chillers eziqhelekileyo kunye neemodeli ze-water chiller ezili-120 ukuze zenziwe ngokwezifiso. Ngomthamo wokupholisa oqala kwi-0.6KW ukuya kwi-30KW, ii-water chillers zethu ziyasebenza kwimithombo eyahlukeneyo ye-laser epholileyo, oomatshini bokucubungula i-laser, oomatshini be-CNC, izixhobo zonyango, izixhobo zelebhu njalo njalo.
