Product Overview

This 20′ UN portable tank is specifically designed for the safe and efficient transport of cryogenic liquids including liquid oxygen (LO2), liquid nitrogen (LN2), and liquid argon (LAr). Built to the highest international standards, this UN T75 type intermodal container combines robust construction with advanced insulation technology for reliable cryogenic service.

The tank features a maximum allowable working pressure of 1.0 MPa and a water capacity of 21,100 liters. With a tare mass of 7,300 kg and maximum payload of 28,200 kg, this container offers excellent transport efficiency. The design complies with multiple international regulations including ISO1496-3, IMDG, ADR, RID, ASME VIII.1 (with U Stamp), US‑DOT CFR49, and CGA341.
