    Tips: Variable frequency drive condensation eliminating methods
    By the impact of air humidity, once the working environment temperature changes greatly, VFD may appear condensation phenomenon and causing liquid water appear on the internal power devices, circuit boards and other parts. The water will produce corresponding conductive channel with the dust, and then the electrical insulating property of VFD will be reduced and even produce short circuit, electronic components failure and other problems.
    Elimination of condensation:

    1. Temperature control
      Setting a filter on the vent can not only preventing a lot of dust into VFD, but also can ensure IP protection level. When the temperature exceeds 40℃, it will start the ventilation system. When the relative humidity exceeds 80%, it will start the heater. Or VFD is completely sealed, effectively putting an end to the salt spray, harmful gases and dust into VFD.
    2. Humidity control
      1) Temperature difference dehumidification method: Install the radiator which is conducive to formation condensation inside VFD, so that the other parts will not form condensation. The condensate formed on the radiator will be discharged through the outlet to ensure that VFD is always maintained relatively dry.
      2) Adsorption and membrane dehumidification method: Set the appropriate adsorption material in VFD for water vapor adsorption to ensure relatively dry environment in VFD. It can also be set with the membrane filter to barrier the water vapor, only allow dry air to pass through the filter so that only relatively dry air can flow into VFD.
      3) Condensation dehumidification method: Set the lowest temperature point inside VFD to let the condensation only generated there, so that to effectively reduce inside relative humidity and making VFD always maintain a relatively dry environment.
