Moisture protection for Aerospace
Dew-point-level moisture control for avionics, optics, composites and long-term preserved assemblies.
The context
What makes this sector different
Aerospace parts are frequently specified to a dew point rather than a humidity percentage, stored for years rather than months, and cycled through extreme altitude temperature swings. That combination puts the requirement above what a general-purpose sachet delivers.
Our approach
Sealed enclosures with desiccant specified to a dew point, verified by indicator cards inside the same barrier. Where silica gel cannot hold the humidity low enough, molecular sieve does.
Moisture risks
What goes wrong in Aerospace
Each of these has its own threshold and its own failure signature. Knowing which one you are fighting is what sets the target humidity.
Optical fogging
Sealed optical assemblies fog permanently once internal moisture condenses on a cold surface.
Composite moisture uptake
Composite laminates absorb water and lose interlaminar strength and glass transition margin.
Avionics condensation
Rapid altitude cycling condenses moisture directly onto powered electronics.
Long-term preservation
Spares held for a decade need protection that does not need re-servicing.
Galvanic corrosion
Dissimilar metal joints corrode rapidly in the presence of condensed moisture.
