Evaporators, are coupled with liquid oxygen tanks (LOX) and they are equipment that enable liquefied gases to evaporate and become usable gases. Briefly, its working principle is used for evaporating the cryogenic liquid passing through it, thanks to the heat it receives from the atmosphere. Evaporators (Vaporizers) are produced from 5000 or 6000 series aluminum finned pipes, aluminum pipes and aluminum box profiles suitable for cryogenic use.
