1,000 kg
A 1 m³ micro-bulk tank holds up to 1,083 kg of liquid oxygen, replacing a bank of high-pressure cylinders; the same range is offered for nitrogen, argon, CO2 and LNG.
10 to 200 m³

Tanks, vessels and gas equipmentFGR-TPV-003
Vacuum-insulated cryogenic tanks for storing liquid oxygen, nitrogen, argon, carbon dioxide or LNG on site, from 1,000 kg micro-bulk tanks to bulk tanks holding up to 100,000 kg.
Tanks, vessels and gas equipmentFGR-TPV-012
A vacuum-insulated bulk tank for storing liquefied industrial gases on site, in vertical or horizontal form, from Hong Hui Machinery.
Tanks, vessels and gas equipmentFGR-TPV-014
Vacuum-insulated stainless steel liquid cylinders for storing and dispensing liquid oxygen, nitrogen, argon or carbon dioxide, from 175 L portable dewars to 1,000 L framed industrial cylinders.
Tanks, vessels and gas equipmentFGR-TPV-006
A vertical vacuum-insulated tank that stores liquid carbon dioxide on site for beverage carbonation, food freezing and industrial use.
On-site gas generation
Where buying liquid gas is not practical, oxygen and nitrogen can be produced on site. PSA (pressure swing adsorption) generators separate oxygen or nitrogen gas from compressed air for continuous supply at the point of use. Cryogenic air separation units (ASUs) produce oxygen, nitrogen and argon at larger scale, as gas for the process or as liquid for storage in a cryogenic tank.
Tanks, vessels and gas equipmentFGR-TPV-015
A cryogenic air separation plant that liquefies and fractionally distils atmospheric air to produce high-purity oxygen and nitrogen, with optional argon recovery.
Tanks, vessels and gas equipmentFGR-TPV-016
A pressure swing adsorption system that separates oxygen from compressed air on site, delivering oxygen gas at 90-95% purity.
Tanks, vessels and gas equipmentFGR-TPV-017
A pressure swing adsorption system that separates nitrogen from compressed air on site, supplying nitrogen gas at selectable purities.
Once a site uses more than a few gas cylinders a day, a cryogenic liquid tank is typically more economical and safer to operate: a single vessel is refilled by tanker, eliminating the handling and changeover of large numbers of cylinders.
Size the tank by the mass of liquid gas you need between deliveries, not only by its volume, and state the medium. Oxygen, nitrogen, argon, CO2 and LNG have different densities and boiling points, so the same tank holds a different mass of each.
The working pressure class sets how much liquid a tank can hold and the pressure available at your outlet. A pressure-building circuit keeps the tank at pressure, and an ambient vaporiser turns liquid into gas at the flow rate your process needs. Oxygen service also requires cleaning to oxygen standards.
Pressure equipment used in South Africa falls under the Pressure Equipment Regulations. The design code and conformity route are confirmed with the manufacturer before you order. Read more in our guide to buying pressure equipment for use in South Africa.
A vacuum-insulated vessel that stores an industrial gas as a very cold liquid, such as liquid oxygen, nitrogen, argon, carbon dioxide or LNG. Storing gas as a liquid takes far less space than compressed cylinders, and a vaporiser turns the liquid back into gas at the flow rate your process needs.
Our cryogenic tank range covers liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAr), liquid carbon dioxide (LCO2) and LNG. Liquid cylinders (dewars) cover oxygen, nitrogen, argon and CO2. The medium is confirmed in your quotation, because it sets the materials, cleaning, fill limit and pressure class.
From about 1,000 kg to 100,000 kg of liquid gas: micro-bulk tanks from 1 m³, bulk tanks from 10 m³ to 200 m³ in vertical or horizontal form, and liquid cylinders from 175 L to 1,000 L. Tell us the gas and the mass you need to store and we will quote the appropriate tank.
Up to 1,083 kg of liquid oxygen, according to the manufacturer's parameter sheet. The usable mass differs for nitrogen, argon, CO2 and LNG and depends on the working pressure class, so it is confirmed in your quotation.
Yes. PSA (pressure swing adsorption) generators produce oxygen or nitrogen gas on site from compressed air, and air separation units (ASUs) produce oxygen, nitrogen and argon at larger scale, as gas or liquid for storage in a cryogenic tank. The right choice depends on the purity, flow and pressure you need.
FGR Online is the registered distributor for Southern Africa for Hong Hui Machinery (Binzhou Honghui Machinery Co., Ltd.), which makes cryogenic storage tanks for liquid oxygen, nitrogen, argon, carbon dioxide and LNG.
