Anti-Oxidation Nitrogen Cabinet 450L ESD Body ATOMFAIR®

The cabinet maintains a controlled low-humidity nitrogen atmosphere between 1% and 60% RH using a Honeywell sensor with ±3% RH accuracy and 0.3% annual drift. Stable gas supply and even distribution of stored items are required to prevent oxidation and moisture damage.

• Humidity Control: The cabinet's humidity control range is 1%-60% RH with an over-humidity alarm that triggers when measured humidity exceeds the set value.
• Nitrogen Flow: Nitrogen flow must be adjusted between 0 and 50 L/min to maintain the desired atmosphere.
• Cabinet Sealing: Magnetic door sealing and tempered-glass viewing doors maintain the inert atmosphere; ensure doors are kept closed during normal use.
• Shelf Loading: Stored items must be distributed evenly across the three adjustable perforated shelves to avoid obstruction of internal circulation.
• Installation Environment: Install the cabinet on a stable indoor surface and verify level installation and door sealing before operation.

This procedure describes the steps to safely initialize and operate the 450L nitrogen cabinet for oxidation-sensitive material storage. Proper installation, gas supply verification, and humidity monitoring are critical to prevent material degradation.

Required Equipment: Nitrogen gas supply, Adjustable perforated shelves, Honeywell temperature and humidity sensor, Over-humidity alarm device

1. Install the cabinet
   Install the cabinet on a stable indoor surface and verify level installation.
2. Connect nitrogen supply
   Connect the nitrogen supply and adjust the flow rate to the desired level between 0 and 50 L/min.
3. Distribute items evenly
   Distribute stored items evenly across the three adjustable shelves to ensure proper internal circulation.
4. Monitor humidity
   Monitor the temperature and humidity display to confirm the humidity stays within the 1%-60% RH range.
5. Configure alarm threshold
   Configure the over-humidity alarm threshold to trigger at the desired humidity level.
6. Maintain door seal
   Keep the door closed during normal operation and inspect the magnetic sealing for integrity.

The 450L anti-static nitrogen cabinet provides controlled low-humidity storage for ESD-sensitive materials, using Honeywell sensing and adjustable nitrogen flow, but requires external nitrogen infrastructure and careful sealing maintenance.

Positive

• Anti-static cabinet body for ESD safety: The 1.2 mm galvanized steel cabinet with anti-static exterior coating is suitable for electrostatic-control areas and ESD-sensitive material handling, reducing static discharge risks during storage.
• Precise Honeywell humidity sensing: Honeywell temperature and humidity sensor delivers ±3% RH indication accuracy with only 0.3% annual drift, enabling reliable long-term monitoring of the low-humidity nitrogen atmosphere.

Trade-offs

• Requires external nitrogen supply: Operation depends on a stable, regulated nitrogen gas source with flow adjustment up to 50 L/min, adding infrastructure and recurring consumable costs for the user.
• Sealing and handling sensitivity: The magnetic door sealing and tempered-glass doors require careful handling during movement and installation; any seal degradation can compromise humidity control and nitrogen retention.
