20FT Cryogenic Liquid ISO Tank Container for Lox Transport
Products Description
Our 20FT Cryogenic Liquid ISO Tank Container is specially designed for the storage and transportation of liquefied gases under cryogenic conditions. It features a robust ISO frame, a stainless steel inner vessel, an insulated outer jacket and a high-vacuum multi-layer insulation system.
Designed for industrial gas logistics and specialized liquid transport applications, this cryogenic tank container can be configured for different media, working pressures, insulation requirements and operating conditions.
Depending on the approved design and configuration, it can be used for liquid nitrogen (LIN), liquid oxygen (LOX), liquid argon (LAR), LNG and other compatible cryogenic liquids.
We provide customized engineering solutions to meet different transportation regulations, customer requirements and project specifications.
Working Principle
How Does a Cryogenic ISO Tank Container Work?
The cryogenic ISO tank container uses a double-wall vessel structure combined with a vacuum insulation system to reduce heat transfer from the external environment to the cryogenic liquid.
Step 1: Cryogenic Liquid Filling
The cryogenic liquid enters the inner vessel through the designated filling pipeline. Filling procedures follow the approved operating instructions and maximum filling limits.
Step 2: Vacuum Insulation
The vacuum space between the inner vessel and outer jacket, together with multi-layer insulation materials, helps minimize heat conduction, convection and radiation.
Step 3: Pressure Management
As a small amount of heat enters the tank, part of the liquid may evaporate and increase internal pressure. Pressure-building coils, regulators and safety devices help manage pressure within the approved operating range.
Step 4: Liquid Discharge
The liquid is discharged through the designated outlet using the applicable pressure differential or an optional pump system.
Step 5: Safety Protection
Pressure relief devices, gauges, valves and monitoring instruments provide protection and operating information during storage and transportation.

How to Choose cryogenic ISO tank container?
Choosing the right cryogenic ISO tank container requires careful consideration of the cargo, operating conditions and transportation requirements.
1. Identify the Cryogenic Medium
Confirm whether the tank will be used for LNG, LOX, LIN, LAR or another cryogenic liquid. Material compatibility and safety requirements vary by medium.
2. Determine the Required Capacity
Select the nominal tank volume according to cargo demand, loading frequency, transportation distance and maximum gross weight limitations.
3. Confirm Working Pressure
The MAWP must be selected according to the cargo characteristics, operating temperature, pressure requirements and applicable design code.
4. Select the Insulation System
High-vacuum multi-layer insulation is commonly used to reduce heat ingress and product evaporation.
5. Confirm Transportation Regulations
Check the destination country's requirements for sea, rail and road transportation, including applicable UN T75, IMDG, ADR/RID and CSC approvals.
6. Select Optional Equipment
Consider whether you need a pump, vaporizer, pressure-building system, flow meter, gas return line or customized valve cabinet.
