Pfannenberg Thermostats and Hygrostats Filters<

In combination with thermostats and hygrostats from the FLZ series, Pfannenberg Filterfans® additionally achieve savings on energy, materials and time plus a significantly longer service life. This results in an optimized environmental balance as well as greater reliability of your producruion process. Suitable for all Pfannenberg Filterfans®.
The FLZ series of twin thermostats integrates two independently switchable thermostats.
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.
The electronic combination device unites thermostat and hygrostat in one housing and monitors the relative humidity and the temperature independently of each other.
