1. A method of generating a pressurized, mixed-phase cryogen, the method comprising:
providing a cryogenic system, the cryogenic system further comprising:
a reservoir containing a liquid cryogen;
an enclosure in which the reservoir is disposed; and
a heat exchange coil immersed in the liquid cryogen, the heat exchange coil having an input end and an output end not immersed in the liquid cryogen;
introducing a pressurized gas to the input end of the heat exchange coil at a first pressure;
cooling the pressurized gas within the heat exchange coil to generate a pressurized mixed-phase cryogen;
collecting the pressurized mixed-phase cryogen within the heat exchange coil;
releasing the pressurized, mixed-phase cryogen at an output end of the heat exchange coil, wherein the releasing further comprises releasing the pressurized mixed-phase cryogen from the output end of the heat exchange coil at a second, lower pressure; and
returning the pressurized mixed-phase cryogen to the enclosure via a return line.
