Moisture protection for Engineering
Protection for machined parts, fabrications, tooling and capital equipment in crates and long-term store.
The context
What makes this sector different
Engineering goods are usually large, usually steel, and usually crated for weeks or months. The enclosure is big, the surfaces are bare, and the desiccant has to be sized for an air volume rather than a carton.
Our approach
Large-format bags sized to crate volume, hung rather than buried so they see the moving air. For oil-filled and vented plant, a breather with an indicating charge that maintenance can read on a walk-round.

Moisture risks
What goes wrong in Engineering
Each of these has its own threshold and its own failure signature. Knowing which one you are fighting is what sets the target humidity.
Corrosion on unpainted surfaces
Machined faces, threads and bores corrode first and are the hardest to reclaim.
Condensation inside crates
A sealed timber crate traps humid air and cycles it against cold metal every night.
Tooling and die damage
Precision tooling in long-term store pits and loses tolerance.
Transformer and oil-filled plant
Breathing equipment pulls humid air across insulating oil on every thermal cycle.
Fastener and hardware seizure
Corroded threads make site assembly slow and expensive.
