Low-Temperature Liquid Transport Semi-Trailer — 26.5 Cubic Meters

Low-Temperature Liquid Transport Semi-Trailer (26.5 Cubic Meters)

Designed for the safe and efficient transportation of cryogenic liquids (such as liquid oxygen, liquid nitrogen, liquid argon, and liquefied natural gas), this 26.5 cubic meter low-temperature liquid transport semi-trailer integrates advanced insulation technology, robust structural design, and reliable safety systems. It is an ideal solution for industries including industrial gas supply, medical care, electronics manufacturing, and energy logistics, ensuring stable and compliant delivery of low-temperature media across long distances.

Core Performance & Design Advantages

1. Optimized Capacity & Insulation Efficiency

With a nominal volume of 26.5 cubic meters, the trailer features a scientifically designed tank structure that maximizes cargo capacity while maintaining excellent weight distribution for enhanced road adaptability. The tank body adopts a double-layer vacuum insulation structure: the inner tank is made of high-quality stainless steel (304/316L) with corrosion resistance and low-temperature toughness, while the outer tank is constructed from high-strength carbon steel for structural stability. The vacuum interlayer is filled with high-efficiency insulation materials and equipped with a multi-layer radiation shield, achieving an ultra-low daily evaporation rate (≤0.2% of total volume) to minimize medium loss and ensure long-distance transportation reliability.

2. Robust Structural & Safety Systems

The semi-trailer chassis is engineered with high-strength steel beams, optimized for load-bearing capacity and fatigue resistance to withstand complex road conditions. Key safety components include:

Pressure relief valves (certified to international standards) that automatically release excess pressure to prevent tank overpressure;

Emergency cut-off valves installed at both the front and rear of the tank for quick shutdown in emergency situations;

Leak detection sensors and temperature/pressure monitoring instruments that provide real-time data feedback to the driver's cab;

Anti-roll bars, rear bumpers, and reflective warning signs to meet road safety regulations and reduce collision risks.

3. Reliable Operation & Easy Maintenance

The trailer is equipped with a high-performance refrigeration unit (compatible with multiple low-temperature media) that maintains stable internal temperatures even in extreme ambient conditions (-40℃ to +40℃). The loading/unloading system features quick-connect fittings and a pressure-regulating valve, enabling efficient and leak-free transfer operations. All key components (such as valves, pumps, and sensors) are sourced from reputable manufacturers, ensuring long service life and easy accessibility for maintenance. The trailer also includes a centralized lubrication system and corrosion-resistant coatings, reducing maintenance frequency and operational costs.

4. Compliance with International Standards

This low-temperature liquid transport semi-trailer meets global safety and quality standards, including ISO, GB, and DOT certifications. It is designed to comply with road transportation regulations for dangerous goods, with features such as anti-lock braking systems (ABS), electronic stability control (ESC), and load-sensing axles to ensure safe driving. The tank body undergoes rigorous non-destructive testing (NDT) and pressure tests to guarantee structural integrity, while the entire vehicle is subjected to comprehensive performance inspections before delivery.

Application Scenarios

Ideal for the transportation of various cryogenic liquids, this semi-trailer serves a wide range of industries:

Industrial gas industry: Transporting liquid oxygen, liquid nitrogen, and liquid argon for metal processing, chemical production, and welding applications;
