Cryogenic Insulated Cylinder

Reliable Cylinders for Transporting Liquefied Gases at Ultra-Low Temperatures

Cryogenic Insulated Cylinder Cryogenic Storage Tanks PRODUCTS

A Cryogenic Insulated Cylinder is a specialized container designed to store and transport liquefied gases at extremely low temperatures, typically below -150°C. These cylinders feature double-walled construction with a vacuum and multi-layered insulation to minimize heat transfer and prevent evaporation. They are essential for safely handling gases like liquid nitrogen, oxygen, and argon in various industrial, medical, and scientific applications.

Product Overview:
Low-temperature gas cylinders are designed for storing, transporting, and utilizing liquid argon, oxygen, nitrogen, carbon dioxide, and liquefied natural gas. Equipped with evaporators for continuous gas supply, they feature international standard connectors and imported valves, customizable for safe transportation. These cylinders are widely used in industries such as chemical, mechanical, shipbuilding, healthcare, electronics, materials, energy, research, and aquaculture. The DPL insulated liquid steel cylinder is part of the DPL cryogenic cylinder series, meeting national standards, and ensures high gas purity through its stainless steel construction.

Product Features:

1. The support system of the inner container is made of stainless steel to achieve low heat loss and high stability.

2. Easy to use, allowing independent operation by a single person.

3. Stores pure cryogenic liquids with a large storage capacity for gas.

4. The cylinder features a high-performance insulation system, ensuring low pressure rise rates in a full liquid state, usually eliminating the need to use the vent valve for pressure relief.

5. Combined use of external pressurizers and built-in vaporizers provides continuous gas or liquid supply within designed consumption limits without needing an additional external vaporizer.
