Product Overview

MINGXIN’s Cryogenic Liquid Semi-Trailers are heavy-duty, large-capacity mobile storage solutions engineered specifically for the bulk road transport of cryogenic gases. Designed to safely and efficiently haul Liquid Oxygen (LOX), Liquid Nitrogen (LIN), Liquid Argon (LAr), Liquid Carbon Dioxide (LCO₂), and Liquefied Natural Gas (LNG), our semi-trailers are the backbone of modern industrial gas distribution and clean energy logistics. We combine advanced thermal insulation technology with lightweight chassis engineering to maximize your legal payload and transport profitability.

Key Features & Design Highlights

  • Maximum Payload Design: By utilizing high-strength steel for the outer jacket, premium S30408 stainless steel for the inner vessel, and a weight-optimized chassis, MINGXIN ensures you can transport the maximum possible volume of gas while strictly adhering to local highway weight regulations.

  • Advanced Thermal Insulation: Wrapped with high-vacuum multi-layer super insulation materials and subjected to rigorous vacuum pumping processes. This guarantees an exceptionally low daily evaporation rate, ensuring the cryogenic liquid remains stable and loss-free over long transit distances.

  • Premium Running Gear: Equipped with world-class axles (e.g., BPW or FUWA), heavy-duty air or mechanical suspension systems, and advanced WABCO ABS/EBS braking systems. This guarantees smooth handling, vehicle stability, and superior safety during highway hauling.

  • Smart Operating Cabinet: Features a centralized, highly integrated operation cabin at the rear. All cryogenic valves, pressure gauges, liquid level indicators, and loading/unloading connections are logically arranged for quick, safe, and intuitive operator access.

  • Rapid Discharge System: Can be equipped with an integrated high-flow pressure build-up vaporizer or an optional cryogenic centrifugal transfer pump, enabling fast and flexible unloading at customer sites.

Technical Specifications

  • Applicable Media: LOX, LIN, LAr, LCO₂, LNG, N₂O.

  • Volume Capacity: Typically ranging from 20 m³ to 57 m³ (Customizable based on regional road transport laws).

  • Working Pressure: Standard options from 0.3 MPa to 1.6 MPa (depending on the payload medium).

  • Insulation Type: High-Vacuum Multi-Layer Super Insulation.

  • Axle Configuration: 2-axle or 3-axle designs available to match tractor-trailer requirements.

  • Manufacturing Standards: Fully compliant with GB, ASME, CE/ADR, or DOT standards for international hazardous materials transport.

Industry Applications

  • Bulk Industrial Gas Distribution: Transporting massive volumes of O₂, N₂, and Ar from Air Separation Units (ASU) directly to steel mills, chemical plants, and manufacturing hubs.

  • LNG Virtual Pipelines: Acting as a mobile pipeline to deliver Liquefied Natural Gas from coastal terminals or liquefaction plants to city gas peak-shaving stations, distributed power plants, and L-CNG refueling stations.

  • Medical Gas Logistics: Delivering bulk quantities of high-purity medical liquid oxygen to hospital centralized storage tanks safely and reliably.

  • Food & Beverage Sector: Transporting bulk LCO₂ and LIN for large-scale cold chain logistics, food freezing, and brewery carbonation.

The MINGXIN Advantage

At MINGXIN, we know that fleet efficiency drives your bottom line. Our Cryogenic Liquid Semi-Trailers undergo strict Non-Destructive Testing (NDT), helium mass spectrometer leak detection, and rigorous road-testing before delivery. Whether you need a standard configuration or a completely customized trailer tailored to specific regional road limits, MINGXIN delivers turnkey transportation solutions that offer lower tare weights, superior vacuum retention, and decades of reliable service.
