Control moisture sources and where liquid can collect
- Desiccant breather
Passing gas encounters the moisture-removing medium. Check flow, saturation indicators, replacement and contamination conditions.
- Silica gel / molecular sieve
The two media have different structures and adsorption characteristics. Select the actual grade, operating conditions and regeneration limits.
- Dew point
Liquid can form when a surface reaches the relevant dew point. Compare moisture conditions with the actual surface temperature.
- Relative humidity (RH)This term
RH compares vapour conditions with saturation at the same temperature. It is not an absolute water quantity independent of temperature.
- Labyrinth seal
Offset features create an indirect path. Confirm the actual orientation, drainage and duty rather than assuming a pressure-tight joint.
A desiccant removes moisture from passing gas, while drainage and labyrinth paths manage liquid by other mechanisms. Dew point and relative humidity describe different moisture conditions.
Conceptual moisture-management elements. Desiccant capacity is finite, and no vent, drain or labyrinth is shown as a guarantee against condensation.
