Dewar Tank Premium Cryogenic Storage for Liquid Nitrogen, Oxygen, and Argon

Dewar Tank, also known as cryogenic dewars, are essential for safely storing and transporting ultra-cold liquids like liquid nitrogen (-196°C), oxygen, and argon. Designed with vacuum-insulated technology, these vessels minimize heat transfer to maintain cryogenic temperatures, making them indispensable in healthcare, manufacturing, research, and beyond. Discover how our high-quality dewars combine superior performance, safety, and versatility to meet your cold storage needs.

Core Applications of Dewar Tank

1. Healthcare & Biotechnology

• Biological Sample Storage: Safely preserve stem cells, vaccines, sperm, and tissue samples at -196°C, ensuring long-term viability for biobanks, fertility clinics, and pharmaceutical labs.

• Medical Procedures: Transport liquid nitrogen for cryotherapy, freezing skin lesions (warts, tumors) with precision during on-site clinical treatments.

• Vaccine Cold Chain: Maintain ultra-low temperatures for mRNA vaccines and temperature-sensitive biologics during storage and distribution.

2. Industrial Manufacturing

• Cryogenic Metal Treatment: Store liquid nitrogen for cryogenic machining, enhancing the durability of aerospace components, gears, and bearings by eliminating residual stresses.

• Food Processing: Flash-freeze seafood, fruits, and vegetables to lock in freshness and nutrients, critical for global cold chain logistics and gourmet food production.

• Welding & Cutting: Supply liquid oxygen and argon for industrial welding processes, ensuring a steady gas supply through integrated vaporization systems.

3. Scientific Research & Energy

• Laboratory Cryogenics: Support low-temperature experiments in physics, chemistry, and materials science, such as superconducting magnet cooling and quantum computing research.

• Renewable Energy: Store cryogenic hydrogen and carbon capture fluids, enabling efficient energy storage and transportation for green technology advancements.

• Astronomy & Space: Maintain ultra-cold environments for telescope sensors and satellite components during ground testing and space missions.

Key Features of Our Dewar Tank

1. Superior Thermal Insulation

• Vacuum-Jacketed Design: Double-walled stainless steel construction with a high-vacuum interlayer reduces heat transfer by 99%, achieving boil-off rates as low as 0.1% per day for long-term cryogen retention.

• Multi-Layer Insulation (MLI): Optional MLI coatings further minimize radiant heat gain, ideal for extreme temperature stability in research and medical applications.

2. Durable & Corrosion-Resistant Materials

• 304/316 Stainless Steel: Inner and outer shells resist rust, chemical corrosion, and thermal shock, ensuring longevity even in harsh industrial environments.

• Leak-Resistant Seals: High-purity copper or polymer gaskets create airtight connections, preventing cryogen loss and external contamination.

3. Safety-Engineered for Reliability

• Pressure Relief Systems: Integrated safety valves and rupture disks automatically activate to prevent over-pressurization, compliant with ASME BPVC Section VIII and EN 13530 standards.

• Leak Detection Ports: Built-in sensors or sampling points enable easy monitoring of vacuum integrity and cryogen levels.

• Ergonomic Handling: Lightweight designs (for portable dewars) and reinforced lifting handles ensure safe transport, while bulk dewars feature forklift slots for industrial use.

4. Customizable Sizing & Configuration

• Portable Dewars: 5L–50L capacities for on-the-go medical treatments, lab deliveries, and small-scale industrial use.

• Bulk Cryogenic Tanks: 100L–10,000L+ for large-scale storage, with options for integrated vaporizers, level gauges, and pipeline connections.

• Specialty Models: Dewars for liquid helium (extra-low temperature resistance) and corrosive gases (nickel-plated interiors).
