Type 7 cryogenic inter-modal tanks are designed to carry cryogenic liquids at very low pressure. They use heavy insulation and a venting system so that any boil-off gas produced by the small amount of heat entering the tank can escape safely, keeping the internal pressure from rising. This design goal yields a normal operating pressure of 25 psi or less. Higher pressures—such as 100–500 psi or thousands of psi—are meant for compressed gas tanks, not cryogenic intermodal tanks. So the best choice reflects the low-pressure, cryogenic nature of these tanks.
