160L Ultra-Low-Humidity Dry Cabinet 1%-10% RH ATOMFAIR®

Description

160L Ultra-Low-Humidity (1%-10% RH) Dry Cabinets

Dry storage cabinet, ultra-low-humidity control

Product Overview

The Atomfair DC-Series AF-DC160C is a 160L dry cabinet configured for 1%-10% RH relative humidity control, with a standard white cabinet body, outer dimensions of 450 x 450 x 1010 mm, inner dimensions of 405 x 420 x 840 mm, and 3 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.

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.

Constraints

This cabinet requires upright transport and level installation with confirmed door sealing and stable power before storing moisture-sensitive materials. The storage environment must maintain closed-door operation and minimize ambient exposure to preserve ultra-low humidity conditions.

Transport Constraint: The cabinet must be transported upright with reinforced outer protection using suitable lifting equipment.
Installation Constraint: Level placement, door sealing, and shelf loading must be confirmed before storing sensitive materials.
Power Constraint: Stable power connection is required, and set-point memory is retained after power interruption.
Operational Constraint: The cabinet door must remain closed during normal use, and extended ambient exposure of stored materials should be minimized.
Validation Requirement: For ultra-low or extreme-low humidity applications, the storage process must be validated before formal production use.

HowTo

FAQ

How does the Honeywell sensor's ±3% RH accuracy and 0.3% annual drift affect long-term reliability of ultra-low humidity storage in the Atomfair DC160C?

The Honeywell sensor provides ±3% RH accuracy, which is sufficient for maintaining the 1%-10% RH target range, but the 0.3% annual drift means recalibration may be needed after extended use to prevent gradual set-point deviation. The sensor's low drift ensures stable readings over typical maintenance intervals, though for extreme-low humidity applications (1%-3% RH), a dedicated model grade (D) with tighter control is recommended. The digital LCD displays real-time humidity and temperature, supporting regular verification against external standards.

Can the Atomfair DC160C dry cabinet be integrated with existing cleanroom monitoring or data logging systems for semiconductor component storage?

Yes, the cabinet offers an optional RS485 PC logging interface that enables real-time data logging and remote monitoring of humidity and temperature, supporting traceability in semiconductor and optoelectronic cleanrooms. Additionally, an over-humidity alarm option triggers when internal RH exceeds the set point, and the nitrogen purge system allows inert-atmosphere management for ultra-low humidity requirements. The ESD-safe anti-static coating option complies with IEC 61340-5 for ESD-sensitive environments.

What installation and handling procedures are critical for achieving stable 1%-10% RH performance with the DC160C in a laboratory or SMT facility?

The cabinet must be transported upright with reinforced outer protection and placed on a level surface to ensure proper door sealing and magnetic gasket contact. After setup, confirm level placement, door seal integrity, and stable power before loading moisture-sensitive components. Minimize door openings to prevent humidity spikes, and for high-risk processes, consider the nitrogen purge or over-humidity alarm options. The automatic dehumidification system requires no consumables, but the Honeywell sensor's calibration drift (0.3% annually) should be monitored for long-term accuracy.

Assessment

The Atomfair AF-DC160C 160L dry cabinet delivers ultra-low humidity control (1%-10% RH) via automatic electronic dehumidification with no consumable desiccants, paired with a Honeywell sensor offering ±3% RH accuracy and low drift. Operational deployment requires careful upright transport, level installation, door seal verification, and process validation before use in critical ultra-low-humidity applications.

Positive

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

Trade-offs

Transport and installation sensitivity: Cabinet must be transported upright with reinforced outer protection, and after installation requires confirmation of level placement, door sealing, shelf loading, and stable power before use.
Process validation for ultra-low humidity: For ultra-low or extreme-low humidity applications, the storage process must be validated before formal production use; nitrogen purge or alarm options are recommended when process risk is high.
