Cryogenic Liquid Tank Truck

Product Overview

A cryogenic liquid tank truck is a specialized vehicle designed for transporting liquefied cryogenic gases. It is suitable for the safe transfer of liquid oxygen, liquid nitrogen, liquid argon, as well as cryogenic media such as liquid ethylene and liquid ethane.

The vehicle combines a highly efficient insulated tank structure with a professional transport chassis design. This configuration ensures transportation safety while effectively reducing evaporation loss of cryogenic liquids during transit.

The overall structure is designed to balance transportation efficiency and operational convenience. Multiple unloading methods can be configured according to different operational requirements. By optimizing tank structure and material technology, the vehicle adopts a lightweight design that increases transport efficiency while maintaining large carrying capacity.

This equipment is widely used for long-distance transportation of cryogenic media in industries such as industrial gas production, energy, and petrochemicals.

Working Principle

Cryogenic liquid tank trucks adopt a double-layer tank structure. The inner tank stores the cryogenic liquid, while the outer shell provides mechanical protection and forms an insulated space. Between the two layers, a high-vacuum multilayer insulation system effectively minimizes heat transfer from the external environment, reducing evaporation loss and maintaining a stable cryogenic temperature inside the tank.

During unloading, the liquid can be discharged using either a cryogenic pump system or a self-pressurization device. The cryogenic pump enables rapid liquid transfer and improves unloading efficiency, while the self-pressurization system generates pressure through controlled vaporization of the liquid, allowing the stored liquid to be discharged smoothly.

Pressure control devices, safety valves, and related piping systems work together to ensure safe and stable operation during transportation and unloading while maintaining the purity and cryogenic condition of the medium.
