Hygrostats switch on control cabinet heaters or filterfans when a preset relative humidity is exceeded. The relative humidity is kept above the dew point and the condensation of water on electrical components and the corrosion of unprotected sheet metal is prevented.
Mechanical hygrostats regulate automatically the humidity inside the enclosures, triggering the heater or fan when a preset relative humidity is exceeded.
To prevent condensation on electric and electronic components, the relative humidity is raised above the dew point.
