Low-Temperature Liquid Transport Semi-Trailer — 36.5 Cubic Meters

Low-Temperature Liquid Transport Semi-Trailer (36.5 Cubic Meters)

Engineered for the safe, efficient, and large-volume transportation of cryogenic liquids—including liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAR), and liquefied natural gas (LNG)—the 36.5 cubic meter low-temperature liquid transport semi-trailer combines advanced insulation technology, heavy-duty structural design, and comprehensive safety systems. Tailored to meet the high-capacity logistics needs of industrial, medical, energy, and manufacturing sectors, this semi-trailer ensures stable, compliant, and cost-effective delivery of low-temperature media across long distances and complex road conditions.

Core Performance & Design Advantages

1. Large-Capacity Optimization & Superior Insulation

Boasting a nominal volume of 36.5 cubic meters, the trailer features a precision-engineered tank structure that balances maximum cargo capacity with optimal weight distribution, enhancing load efficiency without compromising road maneuverability. The double-layer vacuum insulation system is the cornerstone of its performance: the inner tank is fabricated from high-grade 304/316L stainless steel, selected for its exceptional corrosion resistance, low-temperature toughness, and compatibility with diverse cryogenic media. The outer tank is constructed from high-strength carbon steel, reinforced with anti-deformation ribs to ensure structural stability under heavy loads. The vacuum interlayer is filled with high-efficiency insulation materials and equipped with a multi-layer aluminum foil radiation shield, achieving an ultra-low daily evaporation rate (≤0.18% of total volume). This minimizes medium loss, extends storage time, and guarantees reliable transportation even for long-haul missions.

2. Heavy-Duty Structure & Comprehensive Safety Systems

The semi-trailer chassis is built with high-strength alloy steel beams, optimized through finite element analysis to enhance load-bearing capacity, fatigue resistance, and durability—ideal for withstanding the rigors of industrial logistics. A full suite of safety features ensures compliance with global dangerous goods transportation standards:

ISO-certified pressure relief valves that automatically regulate internal pressure, preventing tank overpressure and ensuring operational safety;

Dual emergency cut-off valves (installed at the front and rear of the tank) for rapid shutdown of fluid flow in emergency scenarios, minimizing leakage risks;

Real-time monitoring systems, including temperature/pressure sensors and leak detection alarms, which transmit data to the driver’s cab for immediate visibility;

Reinforced anti-roll bars, energy-absorbing rear bumpers, and high-visibility reflective warning signs, reducing collision risks and enhancing road safety;

Anti-lock braking systems (ABS) and electronic stability control (ESC) to maintain vehicle stability during braking and cornering, even with full loads.

3. Reliable Operation & Low Maintenance Costs

Equipped with a high-performance cryogenic refrigeration unit (customizable for specific media), the trailer maintains stable internal temperatures (-196℃ to -20℃) across extreme ambient conditions (-40℃ to +50℃), ensuring the integrity of sensitive cargo. The loading/unloading system features quick-connect, leak-proof fittings and a precision pressure-regulating valve, enabling efficient, spill-free transfer operations that save time and reduce waste. All key components—including valves, pumps, sensors, and seals—are sourced from globally recognized manufacturers, ensuring long service life and easy availability of spare parts. Additional design highlights include a centralized lubrication system, corrosion-resistant surface coatings, and accessible maintenance points, reducing downtime and lowering long-term operational costs.

4. Compliance with Global Standards & Customization

This 36.5 cubic meter semi-trailer fully complies with international safety and quality standards, including ISO, GB, DOT, and ADR regulations, making it suitable for cross-border transportation. The tank body undergoes rigorous non-destructive testing (NDT), hydrostatic pressure testing, and vacuum tightness testing to guarantee structural integrity and leak resistance. To meet diverse customer needs, customization options are available, including:

Tank material upgrades (e.g., duplex stainless steel for aggressive media);

Additional safety features (e.g., flame arresters, emergency shutdown systems);

Tailored chassis configurations (e.g., number of axles, suspension type) for regional road regulations;

Integrated telematics systems for real-time fleet monitoring and logistics optimization.
