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. This provides an environmental balance through energy reduction.

Combined Hygrostats/Thermostats in one housing ensure temperature inside the control cabinet is always correct and condensation build-up is prevented.

The FLZ 610 includes an additional control for operation of a Filterfan® or heater, turning it off and on based on a set temperature, which saves energy and reduce costs.
