Flexibox 810-900

Free cooling

Free cooling is cost-effective controlled ventilation – the telecom shelter or enclosure is cooled by means of ambient air without a compressor. Dantherm’s Free Air Cooling unit, the Flexibox, provides total heat management and significant energy savings on cooling in telecom sites hosting GSM, UMTS or LTE networks.

 

The Flexibox 900 offers cost-effective and controlled free-cooling ventilation. The solution cools by means of ambient air without using a compressor, generating significant savings in all climates.

The unit comes standard with the Dantherm-developed CC 3000 cooling controller, which allows for settings configuration and live operation monitoring on any standard browser.

The Flexibox 900 can be used as a stand-alone unit or in combination with e.g. existing air-conditioning. This ensures maximum use of passive cooling, prolongs the air-conditioner service life and generates significant OPEX savings.

These units are very suitable for retrofitting into existing systems. The return on investment for the retrofit is achieved especially quickly in base stations, where comfort air-conditioning units run 24/7.
