Product Overview
An airtight display system for long-term preventive conservation of collections sensitive to oxygen, humidity and pollutants. The sealed structure combines humidity control, low-oxygen control, purification and remote monitoring to create a stable display microclimate.
Display-case form, opening method, lighting and environmental-control modules are configured around the collection and exhibition design.
Key Preservation Functions
Airtight Microclimate
Special sealing profiles and silicone gaskets reduce external air exchange.
Humidity Control
Electronic humidity control supports requirements for metal, inorganic and organic collections.
Low-Oxygen Control
Adjustable oxygen concentration helps control pests, mold and oxidation risks.
Air Purification
Gas filtration and self-cleaning control reduce harmful substances and secondary pollution.
Remote Monitoring
Temperature, humidity and related parameters can connect to the intelligent monitoring platform.
Display Case Forms
Freestanding Display Case
For independent display and viewing from multiple sides.
Top-View Display Case
For small or planar objects viewed from above.
Flat Display Case
For paper, paintings, archives and horizontal display.
Table Display Case
For smaller objects and mid- or low-level presentation.
Wall Display Case
For large or continuous displays along exhibition walls.
Opening Options
Opening systems can be configured as automatic swing-out sliding, automatic lifting, wall-case swing-out sliding, or power-assisted top opening according to the display-case form and access workflow.
