450L Extreme-Low-Humidity (1%-3% RH) Dry Cabinets

Dry storage cabinet, extreme-low-humidity control

Product Overview

The Atomfair DC-Series AF-DC450D is a 450L dry cabinet configured for 1%-3% RH relative humidity control, with a standard white cabinet body, outer dimensions of 900 x 600 x 1010 mm, inner dimensions of 855 x 570 x 840 mm, and 3 adjustable shelves.

This model provides extreme-low-humidity storage for highly moisture-sensitive components and process materials that require the strictest dry-storage conditions in this series. It is used to prevent moisture absorption, oxidation, micro-structural degradation, optical haze, solderability loss and other humidity-related damage during storage, inspection, production staging or long-term preservation.

Application scenarios include high-sensitivity electronics storage, semiconductor and optoelectronic cleanrooms, advanced research laboratories, precision optical storage, process-material staging areas, and dry-room support where the lowest humidity grade in this cabinet series is required.

The cabinet integrates automatic electronic dehumidification, high-precision Honeywell temperature and humidity sensing, a digital LCD display for humidity, temperature, operating status and fault information, set-point memory after power interruption, tempered-glass viewing doors, reinforced adjustable shelves and sealed cabinet construction for repeatable daily operation.

Key Features and Advantages
  • Selectable humidity grades are split into individual models: A mid-humidity 20%-60% RH, B low-humidity 10%-20% RH, C ultra-low-humidity 1%-10% RH and D extreme-low-humidity 1%-3% RH, allowing the cabinet to match the actual sensitivity of stored materials.
  • High-precision sensing uses a Honeywell temperature and humidity sensor with ±3% RH accuracy and low annual drift for reliable long-term measurement.
  • Efficient automatic dehumidification removes moisture rapidly, requires no disposable desiccant consumables and supports continuous operation with minimal maintenance.
  • Intelligent microcomputer control retains set parameters after power loss and shows real-time humidity, temperature, operating status and fault codes on the LCD display.
  • Robust sealed construction uses a galvanized steel cabinet body, tempered safety glass, double-frame sealing, magnetic gaskets and a lockable handle for stable dry storage.
  • Perforated adjustable shelves support uniform air circulation and make it easier to store components, instruments and samples of different sizes.

Optional Accessories
  • ESD-Safe Anti-Static Coating: Provides electrostatic protection for ESD-controlled production and storage areas, compliant with IEC 61340-5 handling requirements.
  • Internal LED Illumination: Moisture-resistant interior lighting improves visibility when checking stored parts, labels and shelf positions.
  • Premium Stainless-Steel Body: High-grade structural body option for cleanrooms, corrosive environments or facilities with stricter hygiene requirements.
  • Nitrogen Purge System: Fast-purge gas valve configuration supports accelerated dehumidification and inert-atmosphere management.
  • RS485 PC Logging Interface: Enables real-time data logging, remote monitoring and traceability of cabinet humidity and temperature status.
  • Over-Humidity Alarm System: Microcomputer alarm function is triggered when the internal humidity exceeds the configured set point.
For tailored configurations or formal technical quotations regarding these options, please contact our engineering team.
APPLICATION SCOPE: Engineered for research laboratories, cleanroom environments, semiconductor assembly lines, SMT component rooms, optical workshops and high-tech industrial quality-control centers managing moisture-sensitive electronic, optical, chemical and archival assets.
HANDLING REQUIREMENT: The cabinet should be transported with reinforced outer protection, kept upright, and moved with suitable lifting or handling equipment according to its volume. After installation, confirm level placement, door sealing, shelf loading and stable power before storing sensitive materials.
IMPORTANT NOTICE: Confirm the exact capacity, humidity grade, cabinet body type and optional accessories before ordering. Keep the cabinet door closed during normal use and minimize extended ambient exposure of sensitive materials. For ultra-low or extreme-low humidity applications, validate the storage process before formal production use and consider nitrogen purge or alarm options when process risk is high.

The cabinet requires level placement on a stable surface with secure electrical connection. Door sealing must be verified before use and prolonged door openings avoided to maintain extreme-low-humidity conditions.

  • Electrical Safety: Ensure the cabinet is connected to a stable power supply with proper grounding to prevent electrical hazards.
  • Transport Orientation: Transport the cabinet upright with reinforced outer protection to avoid structural damage.
  • Environmental Exposure: Minimize extended ambient exposure of stored materials by keeping the cabinet door closed during normal use.
  • Process Validation: Validate the storage process for ultra-low or extreme-low humidity applications before formal production use.
  • Optional Alarms: Consider nitrogen purge or alarm options when process risk is high to maintain humidity setpoint.

This procedure describes safe transportation and initial setup of the extreme-low-humidity dry cabinet. Follow these steps to ensure proper installation and avoid damage to the unit or stored materials.

Required Equipment: Lifting equipment, Spirit level, Grounded power cable

  1. Position Cabinet
    Position the cabinet upright on a level surface using suitable lifting equipment.
  2. Verify Level
    Verify that the cabinet is level and adjust if necessary.
  3. Connect Power
    Connect the cabinet to a stable, grounded power outlet.
  4. Set Humidity Setpoint
    Set the desired humidity setpoint via the microcomputer control panel.
  5. Stabilize and Load
    Allow the cabinet to stabilize to the set humidity before loading moisture-sensitive materials.

What is the performance trade-off between selecting the extreme-low-humidity 1%-3% RH model versus the ultra-low 1%-10% RH model for storing highly moisture-sensitive electronics?

The extreme-low-humidity model offers the strictest grade at 1%-3% RH, which provides the lowest moisture environment but requires more rigorous process validation. The source states for ultra-low or extreme-low humidity applications users should validate the storage process before formal production use and consider adding a nitrogen purge or alarm option when process risk is high.

Can the Atomfair AF-DC450D dry cabinet be integrated with an existing facility monitoring system for real-time humidity logging?

Yes, the cabinet supports integration via the optional RS485 PC logging interface. This accessory enables real-time data logging, remote monitoring, and traceability of cabinet humidity and temperature status, as described in the optional accessories list.

What are the critical installation requirements for the AF-DC450D extreme-low-humidity cabinet to ensure proper dehumidification performance?

The cabinet must be transported upright with reinforced outer protection and placed on a level surface after delivery. After installation, the user should confirm level placement, door sealing, shelf loading, and stable power before storing sensitive materials, as noted in the handling requirement section.

The AF-DC450D 450L extreme-low-humidity dry cabinet delivers 1%-3% RH control using automatic electronic dehumidification and a Honeywell sensor, making it suitable for highly moisture-sensitive electronics, optics, and process materials in cleanroom or laboratory environments.

Positive

  • Extreme-low-humidity range (1-3% RH): Achieves and maintains the strictest dry-storage conditions in the series, preventing moisture absorption, oxidation, and micro-structural degradation for the most sensitive components and process materials.
  • Honeywell sensor with low drift: The integrated Honeywell temperature and humidity sensor offers ±3% RH accuracy and 0.3% annual drift, enabling reliable long-term measurement and control without disposable desiccant consumables.

Trade-offs

  • Transport and installation requirements: The cabinet must be transported upright with reinforced outer protection and requires level placement, door sealing verification, and stable power before use, adding setup complexity.
  • Validation needed for extreme-low humidity: For applications below 10% RH, the manufacturer recommends validating the storage process and considering optional nitrogen purge or over-humidity alarm systems to maintain reliability under demanding conditions.
