display cases are widely used because they are useful to display and protect， they offer a protection against vandalism, robberies and any direct damage that could come from visitors.
In addition, often, they are installed for conservation, with the hope that they work as a good against environmental attacks due to microclimate variations, chemical pollution and action of micro-organism.
The interior of a display cases is a relatively air-tight environment. Relicase create a stable inner environment within the display cases. It is ensure your exhibits do not suffer damage from changes in environmental factors outside the case.
Poor management of humidity is one of the key factors that may cause damage to fragile or sensitive exhibits such as those comprised of fabric and paper. In order to keep humidity within a set constant range, we offer two options:
Passive humidity control media in sheet or granulated form.
These absorb excessive moisture in the air to control changes in humidity levels within display cases to ensure the humidity in display cases does not fluctuate.
Active humidity control system.
An electronic constant humidity control system can precisely control and maintain the humidity in display cases. Whether it is required to dehumidify or humidify, the electronic constant humidity control system works around the clock to ensure the humidity level is maintained throughout as specified for a particular exhibit.
The CTH system we provide can be independently installed to maintain a consistent temperature and humidity, and allow for precise control of the microenvironment within a specified volumetric space in a display cases. An external air conditioner can effectively control the temperature and humidity of the display cases.
A very low level of oxygen within display cases is maintained by injecting nitrogen into the interior display cases to displace the oxygen. This effectively prevents damage to the exhibits as a result of oxidation within the display chamber.
Hazardous Substances Control
Pollutants in the air inside display cases such as bacteria, microorganisms, suspended particles, and special corrosive gases are the key causes of irreversible damage to exhibits. Adsorbents,activated carbon fabric and air filtration systems effectively reduce the concentration of the above substances.
