Liquid Cylinders- Packaged Gases Solution
Liquid cylinders offer a safer and more efficient gas storage solution than traditional high-pressure cylinders.
Liquid cylinders are available in various types, each specifically designed for storing and transporting different cryogenic liquids.
Some standard liquid cylinders include a liquid CO2 cylinder, a liquid nitrogen bottle, a liquid oxygen bottle, and a liquid argon tank.

Key Features:
- Inner pressure vessel: Holds the cryogenic liquid under controlled pressure.
- Outer vacuum jacket: Minimizes heat ingress for superior insulation.
- Pressure-building system: Maintains operating pressure for consistent liquid and gas withdrawal.
- Safety valves and gauges: Ensure secure operation and monitoring.
This engineering ensures minimal liquid loss and safe handling of extremely cold gases.

Product Highlights
Liquid cylinders are specially engineered, pressurized containers for the safe storage and handling of cryogenic liquids.
They allow controlled withdrawal of both liquid and gas phases.
A liquid nitrogen cylinder, for example, is equipped with dedicated valves for filling and dispensing,
along with a pressure-control valve and a rupture disk to ensure safe operation under varying conditions.
DSW cryogenic liquid cylinders are designed for maximum efficiency and durability:
- Safe Storage: For nitrogen, oxygen, argon, CO₂, and nitrous oxide
- Durable Stainless Steel Construction: Ensures long service life
- Integrated Pressure-Building System: Enables immediate gas use
- Vacuum Insulation: Minimizes heat transfer for reduced boil-off
- Ergonomic Design: Large diameter handling ring with reinforced support
- Advanced Monitoring: Roto-tel liquid level gauge system (MP & HP models)
- Warranty: Five-year vacuum warranty for peace of mind

Dewar Cylinder Design
The inner pressure vessel is constructed of stainless steel and supported within an outer stainless steel vacuum jacket. The support system is an all-stainless steel internal support designed for low heat leaks and high strength.
The outer vacuum jacket of the liquid cylinder contains an internal vaporizer that converts the cold liquid to gas.
The internal pressure-building system allows immediate use of the cylinder by automatically building pressure to the preset operating pressure and maintaining it during gas withdrawal.
