Installation outside the shelter
Energy efficient Free Cooling solution that can be retrofitted in existing systems.
The return on investment for the retrofit is achieved especially quickly in base stations, where comfort air conditioning units are running 24 hours a day.
The Free-Air units are plug and play and therefore immediately ready for connection and use.
The units are available in two versions for maximum versatility – FCL-IN for indoor installation and FCL for outdoor installation.
The FCL-IN is installed indoors, for when maximum protection against vandalism and adverse weather conditions is your priority
The FCL is installed outside the container, so that the entire interior space can be used for IT equipment. Full access from the outside for maintenance purposes.

Control and monitoring
The Free-Air units are monitored and controlled by the C102 microprocessor. Comfort air conditioning units can be integrated in the existing air conditioning system and also actuated by the C102 controller.

- It directly measures the energy consumption of the Free-Air units and records the operating hours of the comfort air conditioning units
- It provides backup ventilation upon failure of the main power supply or a fault in the comfort air conditioning units
- 48 VDC power supply enables it to be used for emergency backup ventilation
- Monitoring: ModBus onboard, further protocols via WIB 1000
WIB 1000 is user-friendly and offers easy data exchange, monitoring and worldwide suitability.
- Ongoing retrieval of data from the controller
