Mobile CR400B
CR400B
Portable adsorption dehumidifier
The CR400B 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 in applications requiring higher airflow and moisture removal capacity, while maintaining portability.
The designation follows Cotes naming logic:
- C identifies the Cotes adsorption platform
- R refers to the adsorption rotor
- 400 denotes the capacity class
- B originates from Building, reflecting the product family’s original application focus
Position within the Cotes Mobile family
The CR400B is the highest-capacity model within the standard Cotes Mobile range.
Cotes Mobile units are characterised by:
- Integrated handles for manual transport
- Defined, ready-to-deploy configurations
- Robust cabinet construction suited for worksite conditions
- No requirement for permanent installation
Due to its increased airflow and connected load, the CR400B is typically intended for larger spaces or higher moisture loads. Handling may require two persons depending on site conditions.
Mobile units are delivered as standalone systems and do not use Modular add-on interfaces.
TECHNICAL DATA
PORTABLE OPERATION
Designed for temporary and semi-temporary use in construction and technical environments, with integrated handles supporting safe manual transport and repositioning.
APPLICATION KNOW-HOW
Originally developed for building drying, and now widely used in water damage restoration, construction drying, storage protection and other scenarios requiring flexible humidity control. .
ADSORPTION DRYING PRINCIPLE
Rotor-based adsorption dehumidification for reliable moisture removal across varying temperature conditions, including environments where condensation-based systems are less effective.
MOBILE FAMILY DESIGN
Built on the Cotes Mobile concept, featuring robust cabinet construction and defined configurations optimised for redeployment rather than permanent installation.

On this page we highlight some of the more frequently asked questions from customers.
The CR400B is commonly used for construction drying, large-room restoration projects, storage protection, and other temporary humidity control tasks requiring higher air volume.
The CR400B provides higher dry-air capacity (400 m³/h vs. 290 m³/h), increased regeneration airflow (90 m³/h vs. 65 m³/h), and higher moisture removal capacity (1.4 kg/h vs. 1.1 kg/h), making it suitable for larger volumes and higher moisture loads.
No. The CR400B is designed for temporary and semi-temporary use where relocation between areas or sites is expected. However it is not uncommon for some installations to be permanent.
Selection should be based on:
- Required air volume and moisture load
- Ambient temperature and humidity conditions
- Required drying time
- Available electrical capacity
- Regeneration air ducting possibilities
Performance must always be evaluated at documented reference conditions.
