What are the overall strategies to protect a wind turbine from unwanted humidity?

In general, you have two options, depending on the design of the tower and nacelle. Suppose you have a closed design, with limited air infiltration in your structure. In that case, we can create a slight overpressure in the whole structure that prevents air from entering whilst we remove the salt and humidity from the air inside the structure. When overpressure pulls the air from the outside, the air entering is mixed with dry air, leading the salt to crystalise. Here, the salt crystals are pulled onto a tray and the dehumidifier sends salt-free air into the offshore turbine. In this solution, you have protected the entire structure against mould, corrosion, creating an office-like environment for the electronics inside.

The benefits of dry air: 

  1. Avoiding mould and corrosion 

  2. Avoiding electrical faults in your turbines

  3. Safeguarding durability and performance of sensitive equipment

  4. Creating a safer working environment 

  5. Faster, glitch-free turbine commissioning

  6. Lower costs for materials, coating and components
