3M3 Microbulk Tank

3M3 Microbulk Tank

Microbulk tanks are designed for the storage and transportation of cryogenic gases.
These gases include nitrogen, oxygen, argon, and carbon dioxide.
They are stored and transported in a compact and efficient manner.
MicroBulk storage systems are designed for the storage and distribution of gases.
These systems handle moderate to large volumes, typically ranging from 230 to 1,500 liters.
They provide a convenient and cost-effective solution for customers needing a continuous gas supply.

3M3 Microbulk Tank

MicroBulk tanks provide secure on-site storage of cryogenic liquids to increase operational safety, quality, and efficiency.
The product can be utilized in either liquid or gaseous form for applications as varied as food processing and freezing, high-pressure laser cutting, welding, specimen storage, and laboratory applications.
A micro bulk tank is essentially a bulk storage system in miniature. It is used to fill and store dangerous chemicals such as LO2, LAr, LN2, LCO2, and LNG.
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.

DSW, a renowned global supplier, designs and manufactures cutting-edge Cryogenic Microbulk and Nitrogen Microbulk systems.
Our solutions have revolutionized the industrial gas supply industry by offering compact sizes, advanced safety features, and efficient cryogenic gas delivery.
