Passive Microclimate Environmental Control

While simple in theory, in practice, passive microclimate installations are usually only successful when a number of factors are considered. Foremost amongst them are:

  • the humidity level and range desired
  • the ambient conditions outside the enclosure
  • the size of the enclosure
  • the materials used to construct the enclosure
  • the leakage rate of the enclosure
  • the duration of the exhibition
  • the composition and size of the artefact
  • the type and quantity of passive buffer (such as ProSorb)
ProSorb is available in Cassettes, bags, and as drums or cans of loose beads, and can be purchased pre humidified to 35, 40, 45 or 50% RH

Keepsafe Microclimate Systems can provide you with the appropriate materials and the guidance you need for passive humidity control. We can direct you to a web page, engage in a quick phone conversation, assist in determining your enclosure leakage rates, or make an on-site visit and full report.

We are proud to be the North American representative for PROsorb humidity stabilizers.

PROsorb is a state-of-the-art buffering compound for humidity control in museum showcases, and is especially effective at humidity levels commonly found in museum display environments.
