Transportable Vacuum-Insulated Units
What Are Transportable Vacuum-Insulated Units?
A transportable vacuum-insulated unit is a double-wall cryogenic container specifically engineered for repeated transport of liquefied gases, featuring an inner pressure vessel surrounded by a vacuum-insulated outer jacket mounted within a structural frame designed for handling, stacking, and intermodal transport. These units incorporate integrated rollover protection, forklift pockets, tie-down points, and standardized corner castings for compatibility with container handling equipment. Vacuum insulation maintains cryogenic temperatures throughout extended transport durations while robust structural design withstands the dynamic loads of road, rail, and sea transport.
Why Choose Transportable Vacuum-Insulated Units?
Transportable Vacuum-Insulated Units offer several critical advantages:
- Regulatory Compliance: Designed and fabricated to DOT, TC, UN, ADR, and IMDG code requirements for hazmat transport
- Intermodal Compatibility: ISO container frame dimensions enable seamless transfer between truck, rail, and ship
- Extended Hold Times: Vacuum insulation maintains cryogenic temperatures for multi-day transport without venting
- Rugged Durability: Structural frames protect inner vessels from handling impacts and transport loads
- Operational Flexibility: Multiple sizes and configurations available for diverse fleet and logistics requirements

Frequently Asked Questions About Transportable Vacuum-Insulated Units
What transportation certifications do transportable vacuum-insulated units require?
Depending on destination and route, units may require DOT (US), TC (Canada), UN (international), ADR (European road), RID (rail), and IMDG (maritime) certifications. Roben Mfg fabricates units meeting all applicable codes for your specific transport requirements.
How long can cryogenic products be maintained in transportable vacuum-insulated units?
With heat leak rates below 1% per day, our transportable units maintain cryogenic temperatures for extended periods. Liquid nitrogen can typically be held for 30+ days, while liquid helium units achieve 7-14 day hold times depending on design specifications.
Can transportable vacuum-insulated units be used for intermodal transport?
Yes, our ISO-frame transportable units feature standardized corner castings, dimensions, and weight ratings for seamless transfer between truck chassis, rail flatcars, and container ships using standard intermodal handling equipment.
