Lub raj xa cua sov sib pauv hauv ntau yam ntawm austenitic stainless hlau, duplex stainless hlau, nickel alloys, titanium thiab zirconium, tsim rau txhua hom kev sib pauv cua sov, xws li dej hiav txwv txias, condensers, evaporators, cua sov thiab reheaters.
Cov raj xa cua sov siv rau hauv txhua hom kev lag luam txheej txheem. Cov yam ntxwv yuav tsum tau ua yog: vuam ua los ntawm hlaws dai, qhov ntev ruaj khov thiab kev sim ntau yam.
Peb txoj kev cog lus rau kev xa khoom raws sijhawm thiab kev muab cov khoom siv zoo tau ua rau peb tsim kom muaj kev sib raug zoo nrog cov tuam txhab engineering thiab cov neeg siv kawg thoob plaws ntiaj teb.
Txhua lub raj U khoov ntawm peb cov khoom raug kuaj xyuas zoo los ntawm peb pab neeg cov kws tshaj lij ntawm txhua theem ntawm kev tsim khoom kom xa cov khoom zoo tshaj plaws uas tsis muaj qhov tsis zoo rau cov neeg siv khoom.
