Cryogenic Liquid Carbon Dioxide (CO2) Tanker
The Cryogenic Liquid Carbon Dioxide (CO2) Tanker is an advanced, high-precision pressure vessel transport trailer specifically engineered for the safe, low-temperature (-20°C to -40°C under 1.4 to 2.2 MPa pressure) road distribution and bulk hauling of food-grade, industrial, or medical liquid carbon dioxide ($LCO_2$). Built in strict compliance with international pressure vessel and transport codes (such as ASME Section VIII, ADR Class 2, EN 13530, and GB150), it features a double-wall vacuum-insulated design or a high-density polyurethane (PU) / perlite thermal insulation system over a specialized low-temperature pressure vessel shell (such as 16MnDR or 07MnNiVDR steel). Outfitted with a secure rear valve cabinet housing extended-stem cryogenic valves, liquid level differential pressure gauges, dual safety relief valves, and an onboard centrifugal transfer pump or pressure-building coil, it ensures rapid, zero-loss unloading and a low daily boil-off rate. Paired with 3 commercial axles, air ride or heavy mechanical suspension, and WABCO ABS/EBS pneumatic braking with Roll Stability Support (RSS), it provides exceptional highway stability, vacuum longevity, and cryogenic transport safety. Fully certified under ASME, ADR, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Low-Temperature Pressure Vessel & Superior Insulation Architecture
- Cryogenic Grade Vessel Steel: Engineered with specialized low-temperature impact-tested steel (16MnDR / 07MnNiVDR) or austenitic stainless steel S30408, ensuring full ductility and structural toughness at sub-zero operating temperatures down to -40°C.
- High-Vacuum / Ultra-Thermal Retention: Utilizes high-vacuum perlite powder insulation in the annular space between the inner vessel and outer shell, minimizing ambient heat transfer and maintaining stable tank pressure over long transit distances.
- 100% PWHT & NDT Verification: Undergoes furnace post-weld stress-relieving heat treatment (PWHT) and 100% X-ray non-destructive testing on all pressure-bearing welds to guarantee structural reliability.
2. Specialized Cryogenic Valving & Discharge Assemblies
- Extended-Stem Cryogenic Globe Valves: All liquid loading, vapor return, and discharge lines are fitted with extended-stem stainless steel cryogenic valves to prevent stem freezing and seal degradation.
- Dual Safety Relief System: Features dual parallel safety relief valves paired with a three-way changeover valve, allowing continuous overpressure protection and online maintenance without depressurizing the tank.
- Integrated Transfer Options: Can be outfitted with an onboard cryogenic centrifugal pump or a pressure-building coil to allow flexible, rapid unloading into customer storage receivers.
3. Low-CG Sub-Frame & Roll Stability Controls
- Lowered Saddle Sub-Frame: Secured to a heavy-duty Q345B/Q550 structural sub-frame via shock-absorbing saddles, keeping the center of gravity low for maximum highway handling stability.
- WABCO EBS with Roll Stability Support (RSS): Equipped with electronic braking and RSS to automatically apply selective wheel braking when detecting rollover thresholds on sharp curves.
- Reflective Protective Finish: Finished with high-reflectivity polyurethane paint to reflect solar radiation and reduce thermal pressure build-up during summer transit.
Commercial & Logistics Terms
- Warranty Policy: 3 to 5-Year warranty for the inner pressure vessel shell and vacuum insulation performance; 1-Year warranty for axles, valves, and running gear.
- Delivery Lead Time: 40 – 45 working days upon order confirmation and engineering drawing approval.
- Packaging & Shipping: Nude packing; shipped via Bulk Cargo vessel or Ro-Ro vessel.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
