Description

1435L-4 Extreme-Low-Humidity (1%-3% RH) Dry Cabinets

Dry storage cabinet, extreme-low-humidity control

Product Overview

The Atomfair DC-Series AF-DC1435D-4 is a 1435L-4 dry cabinet configured for 1%-3% RH relative humidity control, with a standard white cabinet body, outer dimensions of 1200 x 700 x 1860 mm, inner dimensions of 1155 x 650 x 1680 mm, and 5 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.

This cabinet maintains an extreme-low-humidity environment of 1%-3% RH for highly moisture-sensitive materials. Proper handling and operation are required to prevent moisture damage and ensure stable performance.

  • Moisture Sensitivity: Stored materials require this humidity range to prevent moisture absorption, oxidation, micro-structural degradation, optical haze, and solderability loss.
  • Door Sealing Integrity: The cabinet door must remain closed during normal use and extended ambient exposure of sensitive materials must be minimized.
  • Process Validation: For ultra-low or extreme-low humidity applications, the storage process should be validated before formal production use.

Follow these steps to safely transport, install, and operate the cabinet. Proper setup ensures the cabinet reaches and maintains the target humidity range for sensitive materials.

Required Equipment: Lifting equipment, Level, Stable power supply

  1. Transport
    Transport the cabinet upright with reinforced outer protection and move it to the installation location.
  2. Position
    Place the cabinet on a level surface and connect it to a stable power supply.
  3. Verify
    Verify level placement, door sealing, shelf loading, and power stability before storing materials.
  4. Stabilize
    Allow the cabinet to dehumidify and stabilize until the LCD display indicates the target humidity range.
  5. Operate
    Minimize door opening duration and keep the cabinet closed during normal use to maintain low humidity.

How does the electronic dehumidification system in the Atomfair 1435L-4 cabinet maintain 1-3% RH without disposable desiccants, and what optional upgrade is available for even faster humidity recovery?

The cabinet uses an automatic electronic dehumidification module that requires no disposable desiccant consumables, enabling continuous operation with minimal maintenance. For accelerated dehumidification and inert-atmosphere management, an optional nitrogen purge system is available, which provides fast-purge gas valve configuration.

What options are available to adapt the 1435L-4 extreme-low-humidity cabinet for ESD-controlled cleanroom environments?

An optional ESD-safe anti-static coating is available for the cabinet, compliant with IEC 61340-5 handling requirements, providing electrostatic protection for ESD-controlled production and storage areas. Additionally, a stainless-steel body option is available for cleanrooms or corrosive environments.

What monitoring or alarm capabilities does the 1435L-4 cabinet offer to alert users if humidity deviates from the 1-3% RH setpoint?

The cabinet features an optional over-humidity alarm system that triggers when internal humidity exceeds the configured set point. It also includes an RS485 PC logging interface for real-time data logging and remote monitoring of humidity and temperature status, and the microcomputer control retains set-points after power interruption.

The Atomfair AF-DC1435D-4 dry cabinet provides extreme-low-humidity storage (1%-3% RH) with high-precision Honeywell sensing and maintenance-free electronic dehumidification, but requires careful installation and process validation due to its large capacity and stringent humidity target.

Positive

  • Honeywell sensor accuracy and drift: Honeywell temperature and humidity sensor provides ±3% RH accuracy with 0.3% annual drift, enabling reliable long-term measurement for critical dry storage applications.
  • Consumable-free dehumidification: Automatic electronic dehumidification module eliminates the need for disposable desiccant consumables, reducing ongoing maintenance and operating costs.

Trade-offs

  • Transport and installation constraints: The cabinet requires reinforced outer protection, upright transport, and suitable lifting equipment due to its 1435L volume and dimensions (1200 x 700 x 1860 mm); after installation, level placement, door sealing, shelf loading, and stable power must be confirmed before use.
  • Process validation for extreme-low humidity: For ultra-low or extreme-low humidity applications (1%-3% RH), the storage process must be validated before formal production use; consideration of nitrogen purge or over-humidity alarm options is recommended when process risk is high.
