Intelligent Nitrogen Cabinet

Intelligent Nitrogen Cabinet

Intelligent Nitrogen Cabinet is a high-precision storage solution developed by HYVODA for “moisture-sensitive, oxidation-prone materials” scenarios. It integrates advanced microcomputer-controlled nitrogen filling and dehumidification technology, high-sensitivity gas concentration sensors, and intelligent data management systems to maintain a low-humidity, high-purity nitrogen environment inside the cabinet.

This product addresses critical pain points in traditional storage methods, such as “material oxidation due to insufficient nitrogen protection”, “unstable humidity leading to material degradation”, and “lack of real-time monitoring of internal environmental parameters”. It supports remote monitoring via a computer-based background and multi-modal identity verification, and can automatically adjust nitrogen supply and dehumidification operations based on real-time environmental data. It is an essential equipment for industries such as electronics manufacturing, semiconductors, precision instruments, and aerospace to protect high-value, sensitive materials (e.g., electronic components, precision parts, chemical reagents) from moisture and oxidation.

Features

  1. Precision Humidity Control & Uniform Nitrogen Filling
    Equipped with a multi-point porous nitrogen injection system and a high-precision dehumidification module, the cabinet achieves precise humidity control (adjustable range: 1%-60% RH, control accuracy: ±2% RH) to meet the storage requirements of different sensitive materials. Nitrogen is uniformly injected from multiple pores inside the cabinet, eliminating dehumidification dead zones and ensuring that every corner maintains a stable low-humidity environment. This design effectively prevents moisture absorption and deliquescence of materials (e.g., IC chips, capacitors) and extends their shelf life by over 300%.
  2. Real-Time Nitrogen Purity Monitoring & Automatic Regulation
    A built-in high-sensitivity nitrogen concentration sensor (detection range: 90%-99.99%) continuously monitors the nitrogen purity inside the cabinet. When the purity falls below the user-set threshold (e.g., 95%), the system automatically activates the nitrogen supply valve to inject nitrogen; once the purity reaches the target value, the valve shuts off immediately. This “on-demand supply” mode not only ensures stable nitrogen purity (fluctuation range ≤±0.5%) but also reduces nitrogen waste by over 40% compared to traditional continuous nitrogen supply cabinets.
  3. Dual-System Emergency Protection

 

  • UPS Backup Power Supply: Equipped with a built-in UPS backup power supply that can maintain the operation of core components (sensors, control system, small dehumidifier) for over 2 hours after a power outage. During this period, the cabinet’s airtight structure ensures that the internal humidity does not exceed the safe threshold (e.g., 30% RH) within 6 hours, avoiding sudden moisture damage to materials.
  • Mechanical Emergency Door Opening: In case of power failure or system malfunction, administrators can use a dedicated mechanical key to open the cabinet door, ensuring timely access to urgently needed materials and preventing production delays.

 

  1. Comprehensive Environmental Data Monitoring & Analysis
    The cabinet continuously collects and records key internal environmental parameters, including nitrogen concentration, humidity, temperature, and nitrogen pressure. These data are displayed in real time on the cabinet’s touchscreen panel and synchronized to the remote management background. Users can view historical data curves (e.g., 24-hour humidity changes, weekly nitrogen purity trends) and export detailed reports in Excel/PDF format. This data traceability function helps enterprises comply with quality management standards (e.g., ISO 9001) and quickly locate the cause of material quality issues (if any).
  2. User-Friendly Operation & Airtight Design

 

  • Intuitive Touchscreen Interface: A 7-inch color touchscreen panel allows users to set parameters (e.g., target humidity, nitrogen purity threshold), view real-time data, and switch operating modes (auto/manual) with simple touches—no complex training required.
  • High-Sealing Performance: The cabinet door adopts a double-layer silicone sealing strip and a pressure-compensating hinge design, achieving an airtightness level of ≤0.5L/min (at 1kPa pressure difference). This prevents external moist air from entering and internal nitrogen from leaking, ensuring long-term stability of the internal environment.
  • Safety Alerts: The system triggers audible and visual alerts (red LED light flashing + buzzer) for abnormal conditions, such as low nitrogen pressure, excessive humidity, or sensor failure—prompting users to take immediate action.

 

  1. Multi-Modal Identity Verification & Access Control
    Equipped with an Android industrial computer, the cabinet supports face recognition, fingerprint/vein recognition, and IC card recognition to restrict access to authorized personnel only. This prevents unauthorized opening of the cabinet (which could disrupt the nitrogen environment and expose materials to moisture/oxidation) and records every access event (operator, access time, operation content) in the system log—enhancing the security of high-value material storage.

Applications

  1. Electronics & Semiconductor Industry
    Suitable for storing moisture-sensitive electronic components (e.g., IC chips, LEDs, capacitors) and semiconductor materials (e.g., wafers, photoresists). The low-humidity (≤5% RH) and high-purity nitrogen (≥99.9%) environment prevents component oxidation and moisture absorption, ensuring their electrical performance and reliability. Typical customer: A leading semiconductor component manufacturer in East China.
  2. Precision Instrument & Aerospace Industry
    Used to store high-precision parts (e.g., aerospace engine components, optical lenses) and measuring instruments (e.g., laser interferometers). The stable low-humidity environment avoids corrosion of metal parts and fogging of optical components, maintaining the precision and service life of instruments. Typical use case: An aerospace component supplier uses the cabinet to store critical engine seal parts.
  3. Chemical & Pharmaceutical Industry
    Applied in storing oxidation-prone chemical reagents (e.g., metal powders, organic catalysts) and pharmaceutical raw materials (e.g., certain active pharmaceutical ingredients). The high-purity nitrogen environment isolates air, preventing chemical reactions (e.g., oxidation, hydrolysis) and ensuring the stability of reagent/raw material properties.
  4. Printed Circuit Board (PCB) Manufacturing
    For storing PCB substrates, solder pastes, and flux. Moisture absorption by PCBs can cause delamination during reflow soldering; the cabinet’s low-humidity environment (≤10% RH) eliminates this risk, improving PCB manufacturing yield. Typical customer: A large PCB manufacturer in South China.
  5. Research Laboratories
    Used in university and enterprise R&D labs to store sensitive experimental materials (e.g., nanomaterials, biological reagents, precision sensors). The cabinet’s precise environmental control and data recording functions meet the strict requirements of scientific experiments for storage conditions, ensuring the reproducibility of experimental results.
