Description

98L Mid-Humidity (20%-60% RH) Dry Cabinets

Dry storage cabinet, mid-humidity control

Product Overview

The Atomfair DC-Series AF-DC98A is a 98L dry cabinet configured for 20%-60% RH relative humidity control, with a standard white cabinet body, outer dimensions of 448 x 400 x 688 mm, inner dimensions of 446 x 372 x 598 mm, and 3 adjustable shelves.

This model provides balanced dry storage for materials that need controlled moisture protection without an ultra-dry environment. 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 research laboratories, electronics workshops, incoming-material storage, component staging areas, optical part storage, film and powder cabinets, technical archives and quality-control rooms that need stable humidity management.

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 Atomfair DC-Series AF-DC98A dry cabinet requires controlled installation and transport to maintain sealed integrity. Improper handling may compromise humidity stability and material protection.

  • Transport Restriction: Transport the cabinet upright with reinforced outer packaging to prevent structural damage.
  • Installation Verification: Confirm level placement, door sealing, shelf loading, and stable power before loading sensitive materials.
  • Operational Discipline: Minimize door opening frequency and keep the cabinet closed during normal use to sustain the internal humidity set point.
  • Humidity Range Limitation: Operate the cabinet only within its specified 20%-60% RH range to avoid exceeding the dehumidification capacity.

The Atomfair DC-Series AF-DC98A dry cabinet requires careful installation and operational discipline to maintain its specified humidity range. Follow these steps to ensure proper function and material protection.

  1. Transport
    Transport the cabinet upright with reinforced outer protection to the installation area.
  2. Installation
    Position the cabinet on a level surface and adjust leveling feet for stability.
  3. Pre-Storage Verification
    Confirm level placement, door sealing, shelf loading, and stable power before loading sensitive materials.

What are the limitations of using a mid-humidity (20-60% RH) cabinet for storing moisture-sensitive components compared to ultra-low humidity models?

The Atomfair AF-DC98A maintains 20-60% RH, which is suitable for materials needing controlled moisture protection without an ultra-dry environment. For components requiring lower humidity, such as those sensitive to <10% RH, the low-humidity (10-20% RH) or ultra-low-humidity (1-10% RH) models from the same DC-Series are required. The product description explicitly separates humidity grades into individual models (A, B, C, D) to match material sensitivity.

Can the Atomfair AF-DC98A dry cabinet be retrofitted with a nitrogen purge system for inert atmosphere storage?

Yes, the cabinet offers an optional nitrogen purge system as a fast-purge gas valve configuration for accelerated dehumidification and inert-atmosphere management. This is listed as an optional accessory that must be configured at order; the base model does not include it. The sealed cabinet construction with magnetic gaskets supports such integration for controlled dry storage.

What are the installation and handling requirements for the 98L dry cabinet to ensure proper humidity control?

The cabinet must be transported upright with reinforced outer protection and moved with suitable lifting equipment. After installation, confirm level placement, door sealing, shelf loading, and stable power before storing sensitive materials. The door should be kept closed during normal use to minimize ambient exposure, and for ultra-low or extreme-low humidity applications, the process should be validated before formal use.

The Atomfair AF-DC98A 98L dry cabinet provides reliable mid-humidity control (20%-60% RH) using a Honeywell sensor and automatic electronic dehumidification, making it suitable for general laboratory and electronics storage. However, its limited humidity range and standard steel body require careful consideration for ultra-dry or corrosive environments.

Positive

  • Honeywell sensor with ±3% RH accuracy: High-precision temperature and humidity sensing with low annual drift (0.3%) ensures reliable long-term measurement and stable control.
  • Automatic electronic dehumidification: No disposable desiccant consumables required, enabling continuous low-maintenance operation with rapid moisture removal.

Trade-offs

  • Limited to mid-humidity range: The cabinet controls humidity only between 20%-60% RH, making it unsuitable for materials requiring ultra-low (<20% RH) or extreme-low (<10% RH) storage conditions.
  • Standard body not corrosion-resistant: The standard powder-coated steel body is not rated for cleanroom or corrosive environments; an optional stainless-steel upgrade is required for such applications.
