Microbulk Tank 5000L Vertical Vacuum Jacket Storage Tank For Industrial Liquid CO2

 

Applications

Laser Cutting Fabrication: Continuous high-purity nitrogen or oxygen supply maintaining stable operating pressure without the pressure drop associated with high-pressure cylinder changeovers.

 

Medical and Healthcare Facilities: Centralized medical oxygen or medical air pipeline supply for clinics and hospitals requiring uninterrupted emergency reserves.

 

Analytical Laboratories: High-purity argon and nitrogen gas supply for gas chromatography and mass spectrometry instruments.

 

Electronics and Heat Treatment: Controlled atmosphere purging and shielding gas distribution for metal hardening furnaces and electronics soldering lines.

 

Customization Options
 

Pressure Tier Configuration

Tailored regulator settings for low-pressure applications (1.6 MPa) or high-pressure laser cutting assist gas (up to 3.4 MPa).

Vaporizer Sizing

Upgraded ambient air vaporizer sizing calculated against local peak hourly flow rates (cubic meters per hour) to prevent ice formation during continuous high-draw operations.

Telemetry and Monitoring

Integration of Internet of Things remote liquid level and pressure sensors for automated vendor-managed inventory reordering.

Manifold and Valve Upgrades

Oxygen-cleaned brass or stainless steel cryogenic valves (such as RegO or equivalent global brands), dual changeover manifolds, and custom connection threads.

 

Quality and Compliance

 

1

Inner Vessel Passivation

All internal stainless steel 304 surfaces undergo chemical pickling and passivation to remove organic contaminants, ensuring medical and high-purity gas compatibility.

2

High-Vacuum Processing

Vessels are evacuated, baked, and tested using helium mass spectrometer leak detectors to achieve a vacuum level under 1 x 10 to the -3 power Pa, securing long-term thermal performance.

3

Pressure Vessel Standards

Designed and fabricated under ISO 9001 quality systems, strictly compliant with ASME Section VIII Division 1 (with U Stamp option available) and European CE-PED directives.

4

Routine Testing

100 percent radiographic testing on longitudinal pressure welds, pneumatic leak checks, and strict holding tests for static evaporation rates prior to factory dispatch.

FAQ

 

Q: How does a microbulk tank eliminate the operational inefficiencies of traditional high-pressure gas cylinders?

A: Microbulk tanks eliminate cylinder rental fees, residual gas loss (typically 5 to 10 percent left in standard high-pressure cylinders), and the labor overhead and safety hazards associated with manual cylinder handling. Liquid is stored at lower pressures and converted on-demand via integrated vaporizers, increasing usable gas volume per footprint.

Q: What is the static evaporation rate, and how do you ensure long-term vacuum integrity?

A: The static evaporation rate refers to the percentage of liquid lost to natural boil-off per 24 hours. We achieve low boil-off rates (under 1 percent per day depending on model size) by combining multi-layer superinsulation wrap with molecular sieve getters, followed by high-vacuum baking and helium mass spectrometer leak testing.

Q: Can microbulk tanks be customized for high-pressure fiber laser cutting machines?

A: Yes. For modern fiber laser cutting requiring high assist-gas pressure, we configure vessels with a maximum allowable working pressure of 3.4 MPa (500 psi) and equip them with high-capacity ambient vaporizers to prevent freezing during continuous high-flow cutting operations.

Q: What quality documentation is provided with each microbulk shipment?

A: Each unit ships with a comprehensive Quality Dossier containing Mill Test Certificates for pressure-boundary metals, ASME or CE pressure vessel compliance certificates, helium leak test reports, pressure relief valve calibration certificates, and a cleaning certificate for oxygen service.

Q: Are these tanks compatible with remote telemetry level monitoring systems?

A: Yes. The control panel can be outfitted with digital differential pressure transmitters and telemetry modulators, enabling real-time remote monitoring of tank liquid level, internal pressure, and gas consumption trends for vendor-managed inventory operations.

Q: What technical details are needed to request a formal quotation?

A: To receive a formal quotation and dimensional drawing within 24 hours, provide your target gas medium (LOX, LIN, LAR, or LCO2), required net capacity, peak hourly gas consumption rate, working pressure requirement, and destination port or delivery location.
