MicroBulk Storage Systems – Bulk Gas Supply
Microbulk storage systems provide safe, efficient on-site storage and supply of cryogenic liquids, ensuring consistent gas quality and operational reliability.
A standard Microbulk system includes vacuum-insulated storage vessels, vaporizers, and pressure regulation components, offering a compact alternative to traditional cylinder supply.
Microbulk tanks supply liquid gases such as argon, carbon dioxide, nitrogen, and oxygen at lower operating costs and with improved efficiency.
Widely used in laboratories, hospitals, and industrial facilities, Microbulk systems support applications including food processing, freezing, laser cutting, welding, specimen storage, and laboratory use.

Benefits & Cost-Effectiveness
Microbulk systems have safety features such as pressure relief valves and built-in monitoring systems to ensure safe operation.
The Micro Bulk Tanks store cryogenic liquids safely on site, maximizing operational safety, quality and efficiency.
- Bulk gas supply system–integrated with small-size liquid storage tank, BC, vaporizer, and pipelines;
- High vacuum multi-layer insulation & well-designed structure- -ZERO, liquid gases loss;
- Establish a regeneration warehouse within the interlayer and sustain long-term vacuum strength;
- Minimum low requirements for the condition of the site;
- Connection gas pipeline directly with inter joint is convenient to assemble and disassemble;
- Easy to store and transport liquid gases, including LOX. LN2. LAr. LCO2. LNG etc.;
- Moving base support for forklifts and lifting lugs—Easy change of working location.;
More Flexibility
MicroBulk solutions provide your business with flexibility as it expands.
No longer will you have to deal with switching multiple smaller cylinders.
Select from high-pressure (HP) or very high-pressure (VHP) sizes, including 1,000, 1,500, 2,000, and 3,000-liter tanks installed indoors or outdoors – much more straightforward than standard bulk tanks!
Intermediate Capacity
Micro bulk tanks typically store between 230 and 6,000 litres (61 to 1,585 gallons) of liquefied gas, which is higher than the storage capacity of gas cylinders but lower than that of liquid storage tanks.
Maximum working pressures available include 0.8Mpa, 1.6Mpa, 2.5Mpa and 3.5Mpa; nominal volumes available in 1M3, 2M3, 3M3, 5M3, 7M3 etc.
Many conveniences
Allows uninterrupted gas supplies, remote control, monitoring of capacity and pressure, no cylinder replacement and handling, and reduced inventory.
Increased productivity
Reduced downtime due to gas cylinder replacements, no residual gas returns to suppliers, improved accounting and ordering procedures and minimal inventory requirements.
Safety Improvement
No cylinder leaks, improved safety, eliminating cylinder handling, low-pressure tanks instead of high-pressure cylinders.
