MicroBulk Gas Supply

Microbulk Tanks

A micro bulk gas system is a storage and delivery system for gases, typically used for industrial and commercial applications where a moderate volume of gas is required.
In a micro bulk gas system, the gas is stored in specially designed tanks or vessels with capacities ranging from a few hundred to a few thousand liters.
Consistent high purity
Increased Productivity and Savings
Reduces downtime on cylinder change-outs
Efficient use of production space
No worries about cylinder leaks
High vacuum multi-layer insulation
Application includes storage of LOX, LN2, LAr, LCO2, LNG, etc.
Available in a variety of sizes (230 – 1,500 liters).
Cryogenic Microbulk tank

MicroBulk Storage Systems- Bulk Gas Supply

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

Microbulk gas supply systems 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.
Using a cryogenic microbulk does not require frequent cylinder replacement, causes no liquid residual loss, avoids the damage caused by cylinder operation, and is more reliable, efficient, and economical.

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, making their storage capacity higher than gas cylinders and smaller than 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.
