730L Ultra-Low-Humidity (1%-10% RH) Dry Cabinets

Dry storage cabinet, ultra-low-humidity control

Product Overview

The Atomfair DC-Series AF-DC730C is a 730L dry cabinet configured for 1%-10% RH relative humidity control, with a standard white cabinet body, outer dimensions of 600 x 690 x 1830 mm, inner dimensions of 555 x 640 x 1660 mm, and 5 adjustable shelves.

This model provides ultra-low-humidity storage for MSDs, IC packages, optical devices and polymers that can degrade quickly after moisture exposure. 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 SMT and semiconductor component rooms, optoelectronic cleanrooms, precision optical workshops, research laboratories, industrial quality-control centers, polymer or film storage, and technical archives for moisture-sensitive assets.

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.

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 upright transport with reinforced outer protection and suitable lifting equipment. After installation, level placement, door sealing, shelf loading, and stable power must be confirmed before use.

  • Transport Requirement: The cabinet must be transported upright with reinforced outer protection and suitable lifting equipment.
  • Installation Verification: After installation, confirm level placement, door sealing, shelf loading, and stable power before use.
  • Operational Constraint: The cabinet door must be kept closed during normal use to maintain humidity control.
  • Exposure Minimization: Minimize extended ambient exposure of sensitive materials when retrieving or storing items in the cabinet.

This procedure covers the initial transport, installation, and operational steps for the dry cabinet. Following these steps ensures proper humidity control and safe storage of moisture-sensitive materials.

Required Equipment: Suitable lifting or handling equipment

  1. Transport
    Transport the cabinet upright using suitable lifting equipment and reinforced outer protection.
  2. Level Placement
    Confirm level placement of the cabinet on a stable surface to ensure proper operation.
  3. Door Sealing Verification
    Verify the door sealing by checking the magnetic gasket contact around the entire perimeter.
  4. Shelf Loading
    Load shelves with storage items, ensuring uniform weight distribution and not exceeding the rated capacity.
  5. Power and Setpoint
    Connect the cabinet to a stable power source and set the desired humidity level on the microcomputer controller.
  6. Normal Operation
    Keep the cabinet door closed during normal use to maintain the internal humidity setpoint.

How does the ±3% RH accuracy of the Honeywell sensor affect the reliability of ultra-low humidity control at setpoints near 1% RH?

The Honeywell sensor's ±3% RH accuracy means at a 1% RH setpoint the actual humidity could be as high as 4% RH, making it challenging to maintain a precise 1% condition. The 0.3% annual drift further degrades accuracy over time, so for consistent ultra-low control, periodic calibration or a tighter-sensor specification may be necessary.

Does the standard Atomfair 730L dry cabinet require an optional anti-static coating for use in ESD-sensitive semiconductor production areas?

The standard cabinet body is white powder-coated steel, which does not provide electrostatic protection. For ESD-controlled environments, the optional ESD-safe anti-static coating, compliant with IEC 61340-5, is required to prevent electrostatic discharge damage to sensitive components.

What specific handling and installation procedures are required to maintain the ultra-low humidity environment in the 730L dry cabinet?

The cabinet must be transported upright with reinforced outer protection and moved with suitable lifting equipment due to its 730L volume. After installation, level placement, door sealing, and stable power must be confirmed. During operation, the door should be kept closed and exposure to ambient moisture minimized to maintain the 1%-10% RH range.

This 730L ultra-low-humidity dry cabinet provides 1%-10% RH control using a Honeywell sensor and automatic electronic dehumidification, suitable for moisture-sensitive electronic, optical, and polymer materials. Its robust sealed construction and intelligent control support reliable operation, but careful handling during transport and potential need for validation or optional nitrogen purge in critical ultra-low humidity applications should be considered.

Positive

  • High-precision Honeywell sensor: Honeywell temperature and humidity sensor with ±3% RH accuracy and 0.3% annual drift ensures reliable long-term measurement for sensitive materials.
  • Consumable-free dehumidification: Automatic electronic dehumidification module eliminates the need for disposable desiccant consumables, reducing ongoing maintenance and operational costs.

Trade-offs

  • Handling and transport constraints: The cabinet must be transported upright with reinforced outer protection and moved with suitable lifting equipment; after installation, level placement and door sealing must be confirmed before use.
  • Validation needed for critical applications: For ultra-low or extreme-low humidity applications, the manufacturer recommends validating the storage process before formal production use and considering optional nitrogen purge or alarm systems when process risk is high.
