welded Insulated container

Welded Insulated Container

Cryogenic Storage and Beverage Transport
The welded insulated container and LN₂ Dewar tank are liquid gas cylinders that provide reliable and efficient liquid nitrogen storage solutions.
Using advanced Dewar technology, these specialised containers create a vacuum-insulated environment, effectively minimising LN₂ evaporation.

Key Features:

Vacuum Insulation: DPL series dewar cylinders utilise advanced vacuum insulation technology to minimise heat transfer and maximise cryogenic liquid holding times.
Durable Construction: These cylinders are manufactured from high-quality materials and offer exceptional strength and durability for reliable long-term storage and transportation.
Multi-Gas Compatibility: The DPL series can accommodate cryogenic liquids, including liquid oxygen, nitrogen, argon, carbon dioxide, and liquefied natural gas (LNG). [Optional: Specify any limitations on gas compatibility based on the model.]
Transportation and Storage: DPL series dewar cylinders are suitable for both road transportation of cryogenic liquids and on-site storage and supply.
Level Gauge: Each cylinder comes equipped with a level gauge (float or capacitance type) for accurately monitoring cryogenic liquid volume.
Safety Features: DPL series dewar cylinders incorporate safety features such as a pressure relief valve and a bursting disc for added protection.

Applications:

Liquid nitrogen offers a wide range of applications across various fields. The DSW Dewar Tank is perfectly suited for:

• Medical Research and Cryopreservation: LN2 plays a vital role in medical research, enabling the preservation of blood, organs, tissues, and reproductive cells at ultra-low temperatures.
• Laboratory Experiments: LN2 is a crucial element in numerous laboratory experiments, providing freezing temperatures for various scientific studies.
• Industrial Processes: Certain industrial processes require cryogenic temperatures, and LN2 is a common choice for applications like food freezing and metal treatment.
• Personal Uses (Gardening): LN2 can be a unique tool for gardeners. By spraying weeds with LN2, you can freeze them, allowing for easy removal and conversion into organic fertilizer.
