    CR290B

    Portable adsorption dehumidifier

    The CR290B is part of the Cotes Mobile product family — a range of portable adsorption dehumidifiers developed for temporary and semi-temporary humidity control.

    The unit is designed for construction drying, water damage restoration, and storage protection where higher moisture removal capacity is required while maintaining mobility.

    The designation follows Cotes naming logic:

    • C identifies the Cotes adsorption platform
    • R refers to the adsorption rotor
    • 290 denotes the capacity class
    • B originates from Building, reflecting the family’s original application focus

    Position within the Cotes Mobile family

    The CR290B represents a higher-capacity model within the Mobile range while retaining manual portability.

    Cotes Mobile units are characterised by:

    • Integrated handles for safe manual transport
    • Defined, ready-to-deploy configurations
    • Robust construction suited for active worksites
    • No requirement for permanent installation

    Compared to the CR240B, the CR290B provides increased regeneration airflow and moisture removal capacity, supporting higher drying demand within temporary environments.

    Mobile units are delivered as standalone systems and do not use Modular add-on interfaces.

    What is the CR290B typically used for?
    open close

     The CR290B is commonly used for construction drying, water damage restoration, and temporary humidity control in medium-to-larger rooms where higher drying capacity is required. 

     The CR290B provides higher regeneration airflow (65 m³/h vs. 40 m³/h) and increased moisture removal capacity (1.1 kg/h vs. 0.8 kg/h), making it suitable for higher moisture loads. 

     No. The CR290B is designed for temporary and semi-temporary deployment where relocation is expected. 

    Selection should be based on:

    • Required air volume and moisture load
    • Ambient temperature and humidity conditions
    • Required drying time
    • Electrical supply availability
    • Regeneration air ducting options

    Performance must be evaluated at documented reference conditions.
