The best way to solve problems in archives, exhibition halls, museum repositories

  • How to create an optimum microclimate in archives, exhibition halls and museum repositories?
  • What equipment should be installed to avoid high fixed costs for rehabilitation and reconstruction of valuable exhibits, paintings, books and documents??

In order to achieve these goals, it is necessary to strictly control humidity while storing records, books, literature and valuable museum exhibits!

Using desiccant rotor technology in storage areas allows to maintain recommended relative humidity and necessary air-flowconditions.

Storage Requirements

The recommended microclimatic parameters for optimal storage conditions of museum exhibits:

Object
The relative humidity, RH,%
Temperature conditions, ° C.

45–65%

19–24°С

Paper, papier-mache

50-60%

19–24°С

Anatomical collections

40–60%

19–24°С

Disks, magnetic tape

40–60%

10–21°С

Photos (black and white)

20–30%

2-20°С

Insects and entomological collections

40–60%

19-24°С

Eastern lacquer paints

50–60%

19-24°С

Wood

40-65%

19-24°С

Books, manuscripts

50–60%

19-24°С

Ethnographic materials

40–60%

19-24°С

Organic materials

50-65%

19-24°С

Installation of DT Group Industrial Desiccant dehumidifiers

  • Reduces the costs of rehabilitation and reconstruction of museum exhibits and archives;
  • Creates the necessary microclimate in museums and archives;
  • Prevents development of mildew on the walls of museum repositories and archives;
  • Improves the hygienic condition of premises;
  • Increases lifespan of bearing constructions of buildings.

How does the desiccant dehumidifier work?

The air which should be dehumidified (process air) goes through the desiccant rotor. Water molecules are adsorbed in a special silicagel rotor. Desiccant rotor is regenerated by the second air stream preheated to 90-140 °C. Moisture is removed from the premises in the form of warm moist air.
