195L Rapid Filling Cryogenic Gas Dewar Liquid CO2 Cryogenic Pressure Storage Vessel
Products Description
The 195L Liquid Oxygen Dewar is a double-walled vacuum-insulated cryogenic container engineered for the safe storage and transportation of Liquid Oxygen (LOX), Liquid Nitrogen (LIN), Liquid Argon (LAR), Liquid CO₂ (LCO₂), and LNG. Constructed with SUS304 stainless steel inner and outer vessels, multilayer insulation, and high-vacuum annular space, it achieves a static evaporation rate of ≤2.1%/day (LN₂). Optional working pressures include 1.4MPa, 2.01MPa, and 2.88MPa.

How to Select vacuum dewar
1.Average daily liquid oxygen consumption of more than 100kg → 195L is a cost-effective choice
2.Medical oxygen supply → choose 2.88 MPa high voltage version
3.Industrial cutting → 2.01 MPa is enough
4.Need to place horizontally → Remarks when placing an order
Not sure? Send us your daily gas consumption, we'll recommend the right model within 2 hours.
