    CR100

    Wall-mounted adsorption dehumidifier for onshore wind turbines 

    The CR100 is part of the Cotes Mobile Wind product family — adsorption dehumidifiers developed specifically for retrofit installation in onshore wind turbines.

    Unlike floor-standing Mobile units, the CR100 is designed for wall-mounted installation, typically using a fixed or magnetic wall bracket inside the WTG tower.

    The unit provides controlled dry-air supply to reduce condensation risk and protect electrical cabinets, control systems and internal turbine components.

    Explanation of Naming

    The product designation follows Cotes naming logic:

    • C – Cotes adsorption platform
    • R – Rotor-based adsorption technology
    • 100 – Capacity class within the Mobile Wind range

    The CR100 is positioned directly within the wind-adapted range and does not inherit the “B” (Building) designation.

     

    Position within the Cotes Mobile Wind family

    The CR100 represents a fixed-mounted retrofit solution within the Mobile Wind range.

    Cotes Mobile Wind units are developed for turbines that were not originally designed with integrated dehumidification. The family includes both:

    • Portable floor-standing units (e.g. CR80B-FC / FCS)
    • Wall-mounted turbine units (e.g. CR100 and larger BW models)

    The CR100 is typically selected where:

    • Defined wall placement is preferred over floor installation
    • Stable, dedicated positioning inside the tower is required
    • A compact vertical format suits the internal turbine layout

    Unlike offshore overpressure systems (CWO family), Mobile Wind units are retrofit solutions intended for flexible integration without major structural modification.

    How is the CR100 installed inside a turbine?
    open close

    The CR100 is designed for wall mounting, typically using a magnetic or fixed bracket. It is not intended for floor placement. 

     The CR100 is wall-mounted and not floor-standing. It provides higher dry-air capacity (100 m³/h vs. 80 m³/h) and is designed as a more fixed internal installation rather than a repositionable unit. 

    The CR100 is primarily positioned for onshore retrofit applications. Offshore installations typically require engineered overpressure systems such as the Cotes Wind Overpressure (CWO) family. 

    During standstill, reduced airflow increases condensation risk. Moisture combined with contaminants can accelerate corrosion and reduce electrical insulation resistance during restart.
