Paintings, furniture, linens and other organic materials contain micro organisms which thrive and multiply in high humidity conditions - invariably causing irreversible damage.

Valuable metallic objects and structures stored in museums are susceptible to oxidisation and corrosive degradation.

To avoid expensive and complicated restoration costs, environmental conditions (which are naturally aggressive), will require adjustment and control.

If the relative humidity is maintained within limits using a desiccant dehumidifier, no micro organism or bacteria activity will occur and metallic surfaces will be free from corrosion.
