Miniclima - Climate Control in Museum Showcases

Description

The Miniclima CHD can only be used for climate control in museum display cabinets, showcases and containers that are classified as air & steam-tight. The device serves to control the relative humidity inside the cabinet at a constant level without influencing the internal air temperature.

At about the same size as a large shoe box, the combined dehumidifier and humidifier unit is easily hidden from view in the base of the display showcase.

The museum showcase or cabinet is connected to the Miniclima CHD using two flexible hoses, forming an airtight recirculation system. Air is extracted from the case into the CHD where it is conditioned before being fed back into the cabinet. By default the whole process takes place without mixing system air with ambient air. A slight overpressure can however be achieved in the showcase by adding a small amount of ambient air to the inlet.

The relative humidity is measured directly inside the cabinet with the unit's sensor. The programmable humidity controller in the Miniclima initiates the appropriate action:- dehumidification by condensing or humidification by evaporation. Condensate from the dehumidification process is added to the unit's integral 500 ml water bottle which also provides the reservoir for the humidification process. A two litre water bottle is also available.

The modes of operation "humidification" and "dehumidification" are indicated on the control panel by red neon light spots. The spots extinguish as soon as the set value inside the case is reached. Should the set value not be reached within a preset time, an alarm is activated.

In addition to the integral alarm-LEDs on the panel, external remote alarm signalling is available using the potential free contact, thus providing the user with the possibility to install an external alarming device. The reset button quits the external alarm.

There are currently two size CHD's available (master units):-

  • Model EBC 08 - for sealed cabinets not exceeding 3 m³
  • Model EBC 09 - for sealed cabinets not exceeding 5 m³

If the volume of a cabinet exceeds the capacity of a master unit, dedicated slave units (EBC 08F, EBC 09F), can be added to the system to increase the performance up to the level required. A slave unit is controlled by it's associated master unit.

air distribution boxes        
 

By using Air Distribution Boxes, a single master unit may be able to supply up to six small cabinets simultaneously.

 

       
 

To be able to maintain an accurate record of the measured relative humidity and temperature, the CHD can be equipped with a built-in data logger.

Each device is delivered ready to install, complete with all necessary hoses, hose connections, cables and a detailed installation and operation manual.
