Description
Humidity, Temperature & Oxygen Control
Relative humidity fluctuations force hygroscopic materials (like paper and wood) to constantly expand and contract, leading to warping, cracking, or mold growth. While large facilities use massive HVAC dehumidifiers, microclimate products stabilize individual display cases or archival boxes.
- Pre-Conditioned Silica Gel Cassettes: Unlike common hardware desiccant that strips 100% of moisture, archival silica gels are pre-set to maintain a fixed, precise environment (typically 40% to 55% RH). They absorb moisture when the air is too damp and release it when the air is too dry.
-
- Top-tier brands: PROSorb (ideal for stabilizing the 40–60% RH museum standard) and ArtSorb (designed for higher-humidity sensitivities).
-
- Archival Desiccant Packets: Compact packets placed inside individual storage bins to prevent moisture spikes. Products like the reusable Hydrosorbent Silica Gel Canisters feature color-changing indicator beads that shift from blue to pink when they require oven-recharging.
