Key Points
1. High Storage Capacity: Compared to compressed gas cylinders, Dewar flasks hold a larger volume of gas at relatively low pressure. For instance, a standard Dewar can store gas equivalent to nearly 30 traditional steel cylinders (for oxygen, nitrogen, or argon).
2.Enhanced Safety: It operates at low storage pressure and is equipped with multiple safety protection devices. Its simple and reliable operation further reduces safety risks during use.
3.High Gas Purity: The internal chamber of the Dewar is clean, ensuring the supplied gas maintains high purity. Direct vaporization of cryogenic liquids eliminates secondary pollution risks (e.g., during filling, transportation, or use) that are common with traditional cylinders.
Efficient Gas Utilization: Unlike cylinders that require residual pressure to be left after each use, Dewar flasks enable complete liquid-to-gas conversion with no waste. This significantly lowers gas consumption costs.
Easy Operation: It integrates automatic pressure boost control, a built-in vaporizer, and pressure/liquid level indicators. No external kinetic energy is needed, so it works 24/7 without being affected by power or water outages.
Typical Application Scenarios
Medical Field: Stores medical-grade liquid oxygen for centralized gas supply in hospitals, supporting oxygen delivery in operating rooms, intensive care units (ICUs), and general wards for patients.
Industrial Sector: Supplies liquid oxygen, nitrogen, or argon for metal processing operations such as cutting and welding, ensuring stable gas flow for continuous production.
Scientific Research: Provides cryogenic liquid storage (e.g., liquid nitrogen, liquid oxygen) in laboratories, supporting high-precision experiments like industrial superconductivity research and magnetic resonance (MR) tests.
Catering Industry: Used to store cryogenic liquids (e.g., liquid nitrogen) for special cooking techniques, such as quick-freezing ingredients to preserve texture and flavor.
Aerospace Industry: Facilitates the storage and transportation of liquid oxygen and liquid nitrogen, providing critical gas support for rocket launches, aircraft maintenance, and aerospace component testing.
