Highlights：
Superior Airtightness: Independently tested by the Joint Testing Laboratory for Cultural Heritage Preservation Equipment, the cabinet exchanges air only once every 60 days, providing exceptional environmental stability for museum conservation storage.
Energy-Efficient Humidity Controlled Storage Cabinet: The humidity controlled storage cabinet maintains relative humidity between 10% – 60% RH, supporting preservation requirements for artifacts of various materials.
The humidity control system operates only once every 7–10 days, minimizing energy consumption while maintaining excellent environmental stability.
Advanced Gas Purification – High-efficiency filtration removes:
- Insect eggs
- Mold spores
- Pollutant gases
- Airborne particulate matter
This ensures clean internal air and helps protect sensitive museum collections.
Stable Low-Oxygen Preservation: The low oxygen storage cabinet maintains highly stable oxygen concentrations, with daily fluctuations averaging only 0.2%.
The oxygen regulation system typically requires adjustment only once every five days, delivering energy-efficient environmental control suitable for long-term preventive conservation.
Intelligent Remote Monitoring – Environmental conditions can be monitored remotely through:
- Mobile App
- Computer
- Cloud Platform
Users can monitor in real time:
- Temperature
- Relative Humidity
- Oxygen Concentration
Additional Design Features
- Switchable privacy glass for display and light-sensitive storage
- Intelligent electronic combination lock
- Universal casters for easy movement
- Flexible shelving, drawers, or trolley configurations
Application Modes
The modular system supports multiple preservation functions to meet diverse conservation requirements:

What are museum storage cabinets?
Museum storage cabinets are specialized preservation cabinets designed to maintain stable environmental conditions for museum collections, archives, and cultural heritage objects. They help protect artifacts from humidity fluctuations, oxidation, insects, mold, and airborne pollutants.
What is museum conservation storage?
Museum conservation storage is the practice of preserving collections in carefully controlled environments that regulate humidity, oxygen, cleanliness, and temperature to slow natural deterioration and extend the lifespan of cultural heritage objects.
What is an archival anoxic storage cabinet?
An archival anoxic storage cabinet or low-oxygen storage cabinet, reduces oxygen concentration inside an airtight enclosure using controlled atmosphere technology. The oxygen-depleted environment helps minimize oxidation while also discouraging insect activity and mold growth without the use of chemicals.
Why use a humidity controlled storage cabinet?
A humidity controlled storage cabinet maintains stable relative humidity to prevent cracking, warping, corrosion, mold growth, and other forms of environmental damage that can affect museum collections, archives, books, textiles, and metal artifacts.
