Cryogenic Liquid Cylinders(VGL)

As a low-temperature insulated pressure vessel, gas cylinders are mainly used for storing and transporting liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide, and liquefied natural gas, and can automatically and continuously provide gas. The gas cylinder is designed as a double-layer (vacuum) structure, with an inner liner used to store low-temperature liquids. Its outer wall is wrapped with multiple layers of insulation material, which has strong insulation performance. At the same time, the interlayer (the space between the two layers of containers) is pumped into a high vacuum, forming a good insulation system together.

Product Introduction

The Cryogenic Liquid Cylinder is a vacuum-insulated, double-layered pressure vessel designed for the storage, transportation, and automatic gas supply of cryogenic liquids. It effectively stores liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAR), liquid carbon dioxide (CO₂), and liquefied natural gas (LNG) at extremely low temperatures.

Built with advanced multi-layer insulation and a high-vacuum system, this cylinder provides exceptional thermal efficiency while minimizing liquid loss. It is widely used across medical, industrial, scientific, and energy sectors where high-purity cryogenic gases are essential.


Features

1. Advanced Vacuum Insulation for Maximum Efficiency

Double-layer vacuum structure: The inner container stores the cryogenic liquid, while the outer container houses multi-layer insulation materials and a high-vacuum space to significantly reduce heat transfer and evaporation loss.

Long holding time: Superior insulation ensures longer liquid retention compared to standard storage solutions.

2. Automatic Continuous Gas Supply

Built-in pressure-building coil ensures a stable gas supply without the need for external gasification equipment.

Can provide continuous gas output, making it ideal for cutting, welding, medical applications, and laboratories.

3. Durable & Safe Structural Design

Stainless steel construction for superior corrosion resistance and durability.

Equipped with safety relief valves and pressure gauges for enhanced protection.

Structural integrity maintained even under demanding transport and storage conditions.

4. Easy Handling & Transportation

Ergonomic handling system: Designed with DPL Series mobility features, allowing transport via carts or cranes.

Vertical positioning required: Prevents damage to the vacuum insulation system, ensuring long-term performance.

Lifting points included: Facilitates secure and stable handling when moving over rough surfaces.

5. Versatile Applications Across Industries

Medical & Healthcare – Oxygen therapy, MRI cooling, cryosurgery

Industrial & Manufacturing – Welding, metal cutting, electronics manufacturing

Aerospace & Research – Rocket fuel storage, cryogenic testing

Food & Beverage – Food freezing, carbonation, cryogenic packaging

Environmental & Energy – LNG refueling stations, CO₂ recovery

Notice

Cryogenic liquid cylinders have an inner container and an outer container with an insulated vacuum space between them .Any abuse(dents,dropping.tip-over,etc.)can affect the integrity of the containers insulation system.DPL series containers will allow you to use a hand truck or hoist to handle these loads properly.Do not attempt to move these cylinders by any other means.While moving the cylinder,the following precautions should be observed

1.Never lay the cylinder on its side.Always ship,operate and store the unit in a vertical or upright position.

2.When loading or unloading the container from a truck,use a hand truck,lift gate,crane or parallel loading dock.Never attempt to manually lift the unit. 

3.To move the container over rough surfaces,or to lift the container,attach an appropri-ated sling to the lifting points cut into the welded support posts,and use a portable lifting device that will handle the weight of the container and its contente


Packing and shipping:

For packing:We can packing it wooden box package or according to customer requirements.
For shipment:we have agent forwarder,Can help customers find best freight cost,We suggest customers do business by CIF.
