Wind Farms

Wind Farms – Dehumidification & Moisture Removal

Wind farm turbines naturally have high humidity in the tower. Controlling the moisture inside a turbine is complex and requires a specialist approach.

By controlling the humidity inside wind turbines, the following issues will be eliminated:

  • The risk of condensation, corrosion, electrical faults and mould
  • Operational disruption
  • Damage to equipment and structures
  • Downtime
  • Reduced maintenance

DEHUM has developed a specialist approach to solving the particular issues around wind farms to apply our engineered dry air solutions to wind turbines, both land-based and offshore.

The DEHUM Overpressure System is a method of preventing the ingress of moisture-laden air into these facilities. Airborne moisture is one of the most significant sources of operational disruption, damage to equipment and structures, and costly practical problems inside the nacelles and towers of wind turbines — especially those offshore.

Such airborne moisture combines with salts in the air to cause corrosion and give rise to condensation and bacterial growth. Together, these result in an extensive range of different problems with structures, coatings, mechanicals and electronics, as well as causing electrical glitches and expensive unscheduled downtime.


There are 2 distinct approaches to dealing with these issues:

Specialised DEHUM Wind Farm Turbine dehumidifiers

These, and the DEHUM Overpressure System, provide the easiest and most effective way to limit the combined effects of moisture and salts inside wind turbines, by automatically managing the levels of humidity present.

DEHUM Overpressure System

A complete, dehumidification system designed to help prevent the ingress of moist, salt-laden air into wind turbine nacelles and towers. The DEHUM Overpressure System helps you prevent humidity problems from even arising.
