Packing & Delivery

Dewar Flask Packaging

Manifold Cylinder Pallet Delivery

Dewar packaging is typically used for storing and transporting cryogenic liquids, such as liquid helium, liquid nitrogen, liquid oxygen and liquid argon, etc. This packaging design can effectively reduce heat transfer and maintain the temperature of cryogenic liquids. For example, the Dewar flask mentioned in the search results is a common dewar packaging form, which is used to store gases such as high-purity  liquid helium liquid nitrogen, liquid oxygen and liquid argon.

The functions of manifold cylinder pallet mainly include the following points:

Improve loading and unloading efficiency: The container rack can be loaded and unloaded as a whole, reducing the number of times individual gas cylinders are moved and improving work efficiency.

Ensure transportation safety: Through the container compartments, the position of gas cylinders can be fixed to prevent rolling or collision during transportation, thereby ensuring the safety of the transportation process.

Optimizing storage space: The design of the container compartments enables gas cylinders to be compactly arranged together, effectively utilizing storage space, especially under limited transportation and storage conditions.
