Cotes Cold Store C65C
C65C
Adsorption dehumidifier for cold storage and refrigerated environments
The C65C is part of the Cotes Cold Store product family — adsorption dehumidifiers developed specifically for humidity control in refrigerated and frozen storage environments.
Cold storage facilities are exposed to continuous moisture ingress through door openings, air exchange and product handling. When humid air enters low-temperature environments, moisture quickly condenses or freezes on cold surfaces.
The C65C removes moisture from the air before condensation or ice formation occurs, helping stabilise the internal climate of cold storage facilities.
Unlike refrigeration systems, which primarily control temperature, the C65C uses adsorption dehumidification to control the dew point of the air, reducing condensation and ice formation inside refrigerated environments.
This approach helps improve operational safety, reduce ice formation and support stable climate conditions in large cold storage installations.
Explanation of Naming
The product designation follows Cotes naming logic:
- C – Cotes adsorption dehumidifier platform
- 65 – Capacity class within the product family
- C – Cold Store application variant
The Cold Store designation identifies units optimised for low-temperature environments rather than configurable Modular installations.
Position within the Cotes Cold Store family
The C65C represents the largest-capacity unit within the Cold Store range.
The Cold Store family consists of:
- C30C – compact cold storage dehumidifier
- C35C – mid-capacity unit for larger refrigerated environments
- C65C – high-capacity system for large cold storage facilities
Although based on the same core adsorption technology as the Cotes Modular platform, Cold Store units are delivered as dedicated, pre-engineered configurations rather than modular systems with add-on modules.
This ensures predictable and stable performance in cold environments.
TECHNICAL DATA
COLD STORE HUMIDITY CONTROL
Designed to prevent condensation and ice formation in refrigerated environments where moisture ingress occurs through door openings and air exchange.
ADSORPTION DRYING PRINCIPLE
Rotor-based adsorption drying removes moisture from the air independently of cooling systems.
LOW-TEMPERATURE OPERATION
Engineered for stable operation in cold storage environments where ambient temperatures may fall below freezing.
COLD-STORE OPTIMISED DESIGN
Additional insulation and internal design adaptations help prevent internal icing and ensure stable operation.

On this page we highlight some of the more frequently asked questions from customers.
When humid air enters cold environments, moisture condenses or freezes on cold surfaces. This leads to ice formation, reduced cooling efficiency, safety hazards and increased defrost cycles.
Dehumidification removes moisture before condensation or ice formation occurs.
Refrigeration systems are designed primarily to control temperature. Moisture behaviour depends on the dew point of the air, which cannot always be controlled through cooling alone.
Adsorption dehumidifiers reduce the dew point and prevent condensation and ice formation.
High humidity in cold storage facilities can lead to:
- ice formation on floors and equipment
- reduced evaporator efficiency
- increased defrost cycles
- safety risks for personnel
- product quality issues
Controlling humidity helps maintain stable and safe storage conditions.
Cold Store units are based on the same adsorption technology but are optimised specifically for cold environments. They include additional insulation and cold-environment adaptations and are delivered as fixed configurations rather than modular systems.
