The T75 20FT cryogenic ISO tank container is a 22,000 L UN Portable T75 tank for cryogenic liquefied-gas transportation. The configuration applies ASME VIII-1 Appendix 44 together with IMDG, ADR/RID and CSC requirements, with BV classification and an ISO 1496 frame. The inner vessel uses SA-240M 304N, while the insulation system uses high-vacuum multi-insulation with aluminum foil and an MDMT of -196°C. Available media include LN2, LO2, LAr, LCO2, LN2O, LNG and liquid ethylene, subject to final project confirmation.

For cryogenic iso tank transport, the medium, working pressure, filling degree and insulation structure must be evaluated together. This T75 tank uses a double-wall construction with an SA-240M 304N inner vessel and Q345R outer jacket. High-vacuum multi-insulation with aluminum foil is used between the two vessels, and the MDMT is -196°C. Working pressure is 2.2 MPa and test pressure is 2.99 MPa. These parameters provide the basis for confirming whether the 22,000 L T75 configuration fits the intended cryogenic logistics project.
