For Telecom shelters, enclosures and rooms.

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.

Flexible, quality-minded cooling solutions

Dantherm offers multiple Flexibox solutions of different capacities, input voltage options and controller versions. The 6th generation features the Dantherm CC3000 controller with included dual-zone cooling, night mode and browser-based remote control.

Combine with existing solutions to save energy

The Flexibox as the sole cooling solution is adequate for cooling Telecom base stations in most climate conditions. In warm climates and in climates with high temperature peaks, a combination of free cooling and an air conditioner is a good choice. The combination prolongs the service life of your existing air conditioner and generates significant energy savings, when the free cooling is active.

Free cooling with extended air path protection

All of the Dantherm Free Cooling products operate with a slight overpressure. This ensures that only fine-filtered air enters the enclosed environment. For extreme weather conditions, Dantherm offers extended air path protection: the Dantherm AirMaze (pat.pend). The AirMaze discharges sand, rain, snow and leaves before they reach the filter for maximum protection.

Free Cooling Significant savings Free cooling systems use ambient air to achieve the internal temperature set point. This technique is applicable in all types of climates, since the ambient temperatures often drop below set point during the day, at night time or during the cooler months of the year. bullet bullet bullet bullet
