Free cooling saves energy and operating expenses at Telecom sites, where the application of traditional air conditioners has resulted in very high energy costs. By using free cooling, the overall thermal management running expenditure can be reduced by up to 90%.
Free Cooling – how it works
Dantherm’s Free Cooling solutions create a fine-filtered overpressure. Motorized dampers are recommended to ensure optimum airflow in the shelter and to prevent ambient air from entering the shelter or room.
Total heat management
The Dantherm Free Cooling solutions provide the option of total heat management in the shelter, as the system controls both connected heating and air conditioning systems. Even surveillance and alarms are part of the Free Cooling solution.
6th generation free cooling
The Free Cooling technology has been used by Dantherm for more than a decade and has been through 6 design generations resulting in related know-how build-up.
