Microbulk System Manufacturer | Custom Cryogenic Gas Supply Systems

BluNet is a professional microbulk system manufacturer supplying integrated cryogenic gas storage and delivery systems for industrial, medical, food processing, electronics, laboratory, and other applications. Our microbulk systems combine cryogenic storage, pressure building, vaporization, piping, pressure regulation, instrumentation, and safety equipment to provide a reliable on-site gas supply.

Compared with conventional gas cylinders, a microbulk system can reduce cylinder handling and refill frequency while providing a centralized cryogenic gas storage system. Compared with large bulk cryogenic installations, microbulk systems can provide a more compact solution for facilities with moderate or growing gas consumption.

BluNet can configure and manufacture microbulk gas systems according to gas type, storage capacity, consumption rate, operating pressure, installation conditions, and downstream process requirements.

A microbulk gas system is an on-site cryogenic gas storage and supply system designed for facilities with moderate or continuously increasing gas consumption.

Instead of supplying gas through multiple high-pressure cylinders, the system stores liquefied gas in a microbulk tank. The stored liquid is then vaporized and supplied to the customer’s process through a controlled gas distribution system.

A complete microbulk installation can include:

• Vacuum-insulated cryogenic storage tank
• Pressure-building system
• Vaporizer
• Cryogenic piping
• Filling and venting connections
• Pressure regulation equipment
• Liquid-level measurement
• Pressure monitoring
• Safety relief devices
• Gas outlet and distribution connections
• Telemetry and monitoring equipment where required

Depending on the application and equipment configuration, microbulk systems can be designed for liquid nitrogen (LN₂), liquid oxygen (LOX), liquid argon (LAr), liquid carbon dioxide (LCO₂), and other compatible cryogenic gases.

Manufacturing a complete microbulk system involves more than producing a cryogenic storage tank. The storage vessel, vacuum insulation, pressure-building circuit, vaporizer, cryogenic piping, valves, instrumentation, safety equipment, and gas outlet system must work together as an integrated gas supply installation.

BluNet provides manufacturing and engineering support for integrated microbulk gas systems, including:

• Cryogenic storage vessel manufacturing
• Vacuum insulation system fabrication
• Pressure-building systems
• Ambient or electric vaporization systems
• Cryogenic piping assemblies
• Pressure regulation systems
• Filling and venting systems
• Liquid-level measurement
• Pressure monitoring
• Safety relief equipment
• Gas outlet and distribution connections
• Skid or base-frame integration
• System testing and inspection

The final configuration is selected according to the gas, required storage capacity, consumption rate, working pressure, vaporizer capacity, installation conditions, and downstream gas requirements.

Actual tank dimensions, pressure ratings, insulation performance, instrumentation, and auxiliary equipment are selected according to the gas medium, required storage volume, gas consumption, peak demand, installation conditions, and applicable design standards.

1. Vacuum-Insulated Cryogenic Tank

The cryogenic storage tank is the core component of a microbulk system. The inner vessel stores the cryogenic liquid, while the outer jacket provides the vacuum-insulated structure.

Vacuum insulation helps reduce heat transfer into the inner vessel and limits product evaporation. Tank capacity and pressure configuration are selected according to the gas consumption and operating requirements of the installation.

For projects requiring a complete gas supply solution, the microbulk tank can be integrated with the pressure-building circuit, vaporizer, piping, valves, instrumentation, and gas outlet system.

2. Pressure-Building System

A pressure-building circuit helps maintain the required pressure inside the storage vessel.

When tank pressure falls below the required operating range, a controlled amount of cryogenic liquid can be vaporized and returned to the vessel as gas. This process helps maintain stable storage pressure for gas delivery in suitable system configurations.

3. Vaporizer

The vaporizer converts cryogenic liquid into gas before the gas is supplied to the application.

Depending on gas demand and operating conditions, a microbulk system can incorporate an ambient air vaporizer or another suitable vaporization configuration.

Vaporizer selection depends on factors such as:

• Required gas flow
• Gas type
• Operating pressure
• Ambient conditions
• Continuous or intermittent demand

The vaporizer should be selected according to the actual process demand rather than simply the storage tank capacity.

4. Cryogenic Piping and Valves

Cryogenic piping connects the storage tank with the filling system, vaporizer, pressure-building circuit, gas outlet, and other system components.

Depending on the design, the piping arrangement may include:

• Liquid outlet lines
• Gas supply lines
• Fill connections
• Vent lines
• Pressure-building lines
• Safety relief lines
• Isolation valves
• Check valves
• Pressure regulators

The piping layout is engineered according to the required flow path, gas type, operating conditions, installation arrangement, and downstream application.

5. Instrumentation and Monitoring

Microbulk systems can incorporate pressure gauges, liquid-level indicators, monitoring instruments, and other control equipment.

Telemetry and remote monitoring can also be incorporated into suitable systems. These functions can help users monitor gas inventory and plan deliveries according to actual consumption.

A typical microbulk gas supply process follows this sequence:

1. Cryogenic Delivery and Tank Filling

The cryogenic liquid is delivered to the facility by a suitable tanker and transferred into the vacuum-insulated microbulk tank through the filling connection.

2. On-Site Cryogenic Storage

The liquid remains stored at cryogenic temperature inside the insulated vessel. The vacuum-insulated construction helps limit heat transfer and product evaporation.

3. Pressure Building

When required, the pressure-building circuit helps maintain the operating pressure inside the storage tank.

4. Vaporization

When the application requires gas, cryogenic liquid is directed through the vaporization system and converted into gas.

5. Pressure Regulation and Distribution

The gas passes through pressure-control equipment before entering the facility’s gas distribution system and reaching the production process.

This arrangement provides a centralized gas supply without the repeated replacement of individual cylinders.

Microbulk systems are generally suitable when gas consumption becomes too high for conventional gas cylinder delivery but does not require the capacity of a large bulk cryogenic storage installation.

The appropriate gas supply method depends on consumption, peak demand, required pressure, available installation space, delivery arrangements, and the specific requirements of the application.

Continuous Gas Supply

A properly sized microbulk system can provide a stable gas supply without frequent cylinder changeovers.

Reduced Cylinder Handling

Replacing multiple cylinders with centralized cryogenic storage can reduce manual cylinder handling and simplify gas inventory management.

Lower Delivery Frequency

The larger on-site gas inventory can allow deliveries to be scheduled according to actual consumption rather than frequent cylinder replacement.

Reduced Product Loss

Centralized storage can reduce losses associated with residual gas and repeated cylinder changeovers.

Compact Installation

Compared with a large bulk storage installation, a microbulk system can provide substantial on-site storage within a relatively compact installation, depending on the required capacity and site conditions.

Automated Monitoring

Liquid-level monitoring and telemetry options can help users track inventory and plan refilling more efficiently.

Manufacturing

Liquid nitrogen, liquid oxygen and liquid argon can support manufacturing processes requiring a reliable on-site industrial gas supply.

Metal Fabrication and Welding

Argon, oxygen and other industrial gases can support welding, cutting and metal fabrication processes where continuous gas availability is important.

Food and Beverage Processing

Liquid nitrogen and carbon dioxide can be used for freezing, chilling, food processing and beverage applications.

Healthcare and Medical Facilities

Microbulk oxygen systems can support facilities requiring a dependable oxygen supply, subject to applicable medical-gas requirements and local regulations.

Electronics and Semiconductor Manufacturing

Nitrogen and argon can support inerting, purging and other controlled-atmosphere processes used in electronics and semiconductor manufacturing.

Laboratories and Research

Microbulk systems can provide a stable supply of cryogenic gases for laboratories, research facilities and other scientific applications.

Every facility has different gas consumption, pressure, installation and process requirements. For this reason, a microbulk system should be engineered around the actual operating conditions of the site.
