Cryogenic Transport Trailer
cryogenic trailers are trailers or semi-trailers specifically designed to transport liquefied gases under pressure.
Liquid gases in semi-trailers are typically at extremely low temperatures and high pressures.
With more than 20 years of engineering and manufacturing experience, DSW supplies trailers, semi-trailers, swap bodies, liquid tube trailers, and railcars to safely and efficiently distribute liquid gases, including nitrogen, oxygen, argon, carbon dioxide, hydrogen, natural gas, and more.

Cryogenic trailers transport cryogenic liquids to ensure stability and safety throughout the journey.
Cryogenic liquids are typically liquefied gases at -150 °C or lower, like oxygen, argon, nitrogen, hydrogen, and helium.
Cryogenic tanker trailers also store gases at higher temperatures, including liquefied natural gas (LNG), carbon dioxide, and nitrous oxide.
Feature
Semi-trailers have landing gear (legs that can be lowered) to support them when uncoupled from the tractor unit.
Tanker trailers are a specific type of semi-trailer used to transport liquids, such as fuel, and are typically made from high-quality stainless steel or aluminium to minimize erosion.
Purpose: Cryogenic trailers transport gases such as N2, O2, Ar, CO2, H2, etc.
Design: These Semi trailers are vacuum-insulated and engineered for performance, ease of operation, and safety.
Variety: Cryogenic trailers come in different forms, including:
Mobile Storage: Oversized vessels that haul empty over the road, ensuring product availability and improving onsite logistics.
Truck-Mounted Tanks: High vacuum super-insulated tanks customized for specific applications.
Offshore Skids: Designed for the rigorous demands of the offshore well services industry.
Nitrogen Pumping Equipment: Customizable for various vaporization capacities.
Cryogenic Vaporizers and Heat Exchangers: Used for industrial gases, rare gases, LNG, and other hydrocarbons.
