MicroBulk Storage Systems- Bulk Gas Supply

MicroBulk tanks provide secure on-site storage of cryogenic liquids to maximize operational safety, quality, and efficiency.
A microbulk system typically consists of special insulated vessels, vaporizers, and regulators.
MicroBulk systems supply you with access to liquid gases like argon, carbon dioxide, nitrogen and oxygen at competitive rates.

Microbulk Tanks are innovative gas storage platforms for cryogenic laboratories, hospitals, and other gas users.
The product can be used in liquid or gaseous form in applications as diverse as food processing and freezing, high-pressure laser cutting, welding, specimen storage, and laboratory use.
The use of a Cryogenic Microbulk does not need frequent replacement of cylinder, no liquid residual loss, avoids the damage caused by the operation of the cylinder, and is more reliable, efficient, and economical.

3M3 Microbulk Tank

Benefits & Cost-Effectiveness

Microbulk systems have safety features like pressure relief valves and built-in monitoring systems to ensure safe operation. Micro Bulk tanks provide secure on-site storage of cryogenic liquids to maximize 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, even BARELY 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
Microbulk systems typically hold between 230 and 6,000 liters (61 to 1,585 gallons) of gas, making their storage capacity higher than gas cylinders while smaller than liquid storage tanks.
The maximum working pressures available are 0.8Mpa, 1.6Mpa, 2.5Mpa and 3.5Mpa; the nominal volumes available are 1M3, 2M3, 3M3,5M3, 7.5M3 etc.

Many conveniences
Convenience, allowing uninterrupted gas supply, remote control and monitoring of pressure and capacity, no cylinder handling and replacement, and reduced inventory management.

Increased productivity and savings
Decreased downtime for gas cylinder changes, no residual returns to gas suppliers, more efficient accounting and ordering procedures, minimal inventory maintenance requirements, and productive use of gas for labor.

Safety Improvement
Improved safety, elimination of gas cylinder handling, no cylinder leaks, low-pressure tanks instead of high-pressure cylinders.
