When used with enclosure heaters and fan filter units, Enclosure Hygrostat keeps the relative humidity (RH) levels of cabinets below the dew point and prevents condensation forming on electrical components. Easy snap on mounting and screw terminal for electrical connection make the hygrostat ideal for applications combined with heaters or fan filters for precise control of humidity levels. 

Hygrostats switch on electrical enclosure 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. A new electronic combination device unites the thermostat and hygrostat in one housing.
