Gas Withdrawal Circuit
The gas withdrawal circuit vaporizes cryogenic liquid and warms it to ambient temperature for use in the final
application. Opening the gas withdrawal valve (V-3) allows liquid, driven by the pressure within the vessel,
to flow through the vaporizer (VC-1). The vaporizer uses heat from the ambient air to convert the liquid into a
gas and warm it. The vaporizer, like the pressure building coil, is attached to the inside surface of the vacuum
jacket. The vaporizer is located in the upper ¾ of the jacket, the pressure builder in the lower ¼.
