PORTABLE OPERATION
Designed for retrofit installation and flexible placement inside wind turbine towers, with integrated handles supporting safe manual transport and repositioning.
APPLICATION KNOW-HOW
Developed specifically for onshore wind turbines where humidity control was not originally integrated, supporting both targeted cabinet protection and general tower climate stabilisation.
ADSORPTION DRYING PRINCIPLE
Rotor-based adsorption dehumidification for reliable moisture removal across varying temperature conditions, including low-temperature and standstill scenarios where condensation risk increases.
MOBILE WIND FAMILY DESIGN
Built on the Cotes Mobile concept and adapted for wind turbine environments, featuring defined configurations and wind-adapted filtration rather than permanent integrated overpressure systems.

The unit is typically used to supply dry air inside the WTG tower, reducing condensation risk and protecting electrical cabinets and control systems.
Both variants share the same drying performance.
The difference lies in the filtration configuration:
- FC provides wind-adapted filter cassette protection.
- FCS includes an enhanced filter cassette system for environments with higher contamination levels.
The CR80B-FC / FCS is primarily positioned for onshore wind retrofit applications. Offshore installations typically require engineered overpressure systems such as the Cotes Wind Overpressure (CWO) family that creates an overpressure while filtrating salt from the air.
During standstill, ventilation is reduced and condensation can form on internal surfaces with temperature fluctuations. Moisture combined with salt or contaminants increases corrosion risk and may reduce electrical insulation resistance during restart. Controlled humidity reduces this risk.
