The vaporization and heating of cryogenic gas and fuels is a very complex process mainly due to the high pressures involved. The extreme operating conditions associated with cryogenic gases are the ultra-low temperature, extreme pressure expansion.

The Dryheaters can be employed are cryo-gas heaters that provide optimum vaporization and heating results in liquid-to-gas phase change operations in most common cryogenic fluids such as hydrogen, oxygen, nitrogen and carbon-di-oxide.
