Liquid Gas Dewar Supplier

Liquid Gas Dewar Supplier — vessels and refills for every liquefied gas

As a liquid gas Dewar supplier, REAL GAZ offers vessels for liquid nitrogen, oxygen, argon, carbon dioxide and specialty cryogens, with refill logistics included.
Our engineers help you decide between non-pressurised flasks, pressurised liquid cylinders and larger tank-style Dewars.

Equipment is chosen according to ISO 21029-1, EN 1251 and ISO 10156 for gas and material compatibility.

Liquefied gases are chosen because they pack a huge amount of gas into a small volume. One litre of liquid argon yields about 780 litres of gas, and one litre of liquid oxygen about 860 litres. That density makes delivery efficient but demands robust safety devices. REAL GAZ explains the vaporisation rate you can expect from each vessel, so your process does not suffer from icing or pressure drop at peak demand. We also supply regulators, hoses and vaporisers designed for cryogenic service, so the full path from vessel to point of use is covered. Sites that change their product mix, for example moving from nitrogen chilling to argon shielding, can exchange vessels without rebuilding the whole installation, provided the fittings are compatible with the new gas.

🏭 Where Liquid Gas Dewars Are Used

🥩 Food freezing — pressurised liquid cylinders feed tunnels and chillers with a steady nitrogen flow;
🏥 Healthcare — liquid oxygen units support medical gas installations under hospital procedures;
🌱 Agriculture — semen and embryo banks keep valuable genetics at a stable cryogenic temperature;
🔩 Metalworking — argon and nitrogen supplied from Dewars support laser cutting and heat treatment.

🔄 From Flask to Liquid Cylinder

open flasks give flexibility for small manual tasks;
pressurised liquid cylinders deliver gas or liquid at 1.5 to 22 bar for continuous use;
cryogenic tanks suit sites with high daily consumption and a dedicated supply area.
