320L Dual-Flow Energy-Saving Nitrogen Cabinet

Research-grade laboratory product

Product Overview

The 320 L configuration uses a standard white cabinet body, a humidity control range of 1%-60% RH, outer dimensions of 900 × 450 × 1010 mm, inner dimensions of 855 × 420 × 840 mm and 3 adjustable shelves.

This dual-flow energy-saving nitrogen cabinet is designed for low-humidity storage tasks where fast recovery after door opening and reduced unnecessary gas consumption are both important. It supports moisture-sensitive materials that require controlled nitrogen-assisted drying while improving atmosphere recovery and lowering routine nitrogen demand.

Typical application areas include research laboratories, electronics workshops, component staging rooms, optical storage spaces and inspection environments where cabinet doors may be opened more frequently during routine work. This body type suits general laboratories, inspection rooms and organized storage areas.

The cabinet combines 1.2 mm galvanized steel cabinet with white exterior panels, tempered-glass viewing doors and magnetic sealing, dual-flow nitrogen management, automatic switching between large-flow and small-flow operation, tempered-glass viewing areas and perforated adjustable shelves for stable day-to-day cabinet performance.

  • RS485 communication interface for PC-side monitoring and recorded cabinet-status management.
  • Over-humidity alarm device that triggers when measured humidity exceeds the configured set value.
  • If optional items are required, please contact inquiry@atomfair.com.
APPLICATION SCOPE: Suitable for research laboratories, electronics workshops, component staging rooms, optical storage spaces and inspection environments that require low-humidity nitrogen-assisted storage with rapid recovery after cabinet access.
HANDLING & STORAGE: Install the cabinet on a stable indoor surface, keep the door closed during normal use, distribute stored items evenly across the 3 shelf levels, protect structural and sealing components during movement, and use reinforced wooden-crate packaging when shipment protection is required. Verify stable gas-supply conditions before operation.
IMPORTANT NOTICE: Confirm the correct model, cabinet body type, capacity and optional accessories before ordering. Inspect the cabinet after delivery, verify level installation and door sealing, and do not exceed the stated shelf-loading or application conditions. Confirm utility conditions such as power and gas connections before formal use.

The cabinet requires a stable indoor surface and a verified compressed nitrogen supply to maintain controlled low-humidity conditions. Door sealing integrity must be preserved and shelf loading must remain within the stated capacity to prevent structural or functional failure.

  • Installation Surface: Position the cabinet on a level, vibration-free surface to ensure correct door sealing and nitrogen flow distribution.
  • Gas Supply Verification: Confirm that the nitrogen supply pressure and flow rate match the cabinet's inlet requirements before connecting the gas line.
  • Load Distribution: Arrange stored items evenly across all three shelves to avoid overloading any single shelf and to promote uniform airflow.
  • Door Seal Maintenance: Keep the door closed during normal operation and inspect the magnetic seal periodically for damage or debris that could compromise humidity control.
  • Transport Protection: Use reinforced wooden-crate packaging when moving the cabinet and protect all structural and sealing components from impact.

Follow these steps to install the cabinet, connect the nitrogen supply, and begin low-humidity storage. Proper setup ensures rapid atmosphere recovery after door opening and minimizes unnecessary nitrogen consumption.

Required Equipment: Compressed nitrogen source with regulator

  1. Position the cabinet
    Place the cabinet on a stable, level indoor surface away from direct sunlight and heat sources.
  2. Connect the nitrogen supply
    Attach the nitrogen line to the cabinet inlet and verify that the gas pressure is stable and within the operating range of the flow meters.
  3. Arrange stored materials
    Distribute moisture-sensitive items evenly across the three adjustable shelves, ensuring nothing blocks the perforated airflow openings.
  4. Seal the cabinet
    Close the tempered-glass door firmly and confirm the magnetic seal engages along the entire perimeter to maintain a low-humidity environment.
  5. Configure and start operation
    Power on the cabinet, set the desired humidity setpoint within the 1%-60% RH range using the automatic controller, and allow the system to stabilize.

How does the dual-flow nitrogen management balance recovery speed and nitrogen consumption for frequently accessed storage cabinets?

The dual-flow system automatically switches between large-flow (15-50 L/min) and small-flow (1-5 L/min) operation. Large-flow mode provides fast atmosphere recovery after door opening, while small-flow mode reduces unnecessary nitrogen use during idle periods. This automatic switching eliminates manual intervention and optimizes the trade-off between recovery performance and gas consumption.

What are the minimum achievable humidity conditions and material compatibility constraints for this nitrogen cabinet?

The cabinet achieves a minimum humidity of 1% RH with a control range of 1%-60% RH. It is designed for moisture-sensitive electronic parts, optical components, and frequently accessed laboratory materials. However, it cannot sustain humidity below 1% RH, so ultra-dry storage requirements below that threshold may not be supported without additional equipment.

What infrastructure is required for proper installation and operation of the 320L dual-flow nitrogen cabinet?

The cabinet requires a stable indoor surface, a power supply for the automatic control system, and a stable gas-supply connection for nitrogen. The unit measures 900×450×1010 mm externally and must be installed level with door sealing verified. For shipment, reinforced wooden-crate packaging is recommended. The door must remain closed during normal use and stored items distributed evenly across the 3 perforated shelves to ensure proper airflow and sealing.

The 320L Dual-Flow Energy-Saving Nitrogen Cabinet (AF-DFNC320) provides automatic dual-flow nitrogen control for rapid humidity recovery and reduced gas usage, making it well-suited for laboratories requiring frequent access to moisture-sensitive materials. Its sealed galvanized steel construction ensures a stable low-humidity environment, though operation depends on a reliable nitrogen supply and proper installation.

Positive

  • Dual-Flow Nitrogen Management: Automatic switching between large-flow (15-50 L/min) and small-flow (1-5 L/min) enables fast atmosphere recovery after door opening while minimizing unnecessary nitrogen consumption, improving operational efficiency for frequently accessed storage.
  • Sealed Controlled Environment: The 1.2 mm galvanized steel cabinet with magnetic sealing and tempered-glass viewing doors provides a robust barrier against ambient humidity, while perforated adjustable shelves promote uniform airflow distribution.

Trade-offs

  • Nitrogen Supply Dependency: The cabinet requires a stable external nitrogen supply with verified gas conditions before operation, adding infrastructure cost and maintenance overhead for facilities without existing gas lines.
  • Installation and Handling Sensitivity: The unit must be placed on a stable indoor surface, kept closed during normal use, and requires reinforced packaging for shipment; improper handling may compromise door sealing or structural integrity.
