'Thermostats are used as temperature controllers and thus for controlling filter fans or control cabinet heaters. They are designed as openers/closers and changers. In combination with control cabinet heaters, in addition to temperature control, especially in outdoor applications, they can ensure that the control cabinet is 'artificially' dehumidified. This means that the temperature is kept above the dew point so that no water precipitates from the air and short circuits can occur due to condensation. The combination with filter fans offers additional energy, material and time savings and thus a better environmental balance and more safety in the production process through reduced energy consumption and improved efficiency of the filter fans. The range of twin thermostats combines 2 thermostats in all combinations for complex switching tasks.
