Telecom providers continue to face increasing energy prices and pressure to reduce energy consumption. 86% of an operator’s energy consumption stems from network infrastructure. This Mexican mobile operator achieves a total site energy savings of 25% and a comparable 89% energy savings on cooling with a total heat management system at their telecom shelters.

Meeting the network challenge

There is no doubt that we live in a more connected world than ever.  Network traffic (mobile & wired) is expected to nearly double over the next 3 years.  During the same time, the average network speed will also double.  According to the ITU ICT Facts and Figures 2015 report, there will be more than 7 billion mobile cellular subscriptions by the end of 2015, corresponding to a penetration rate of 97%, up from 738 million in 2000.

How will network operators supply adequate capacity to meet this growing demand for data?  Network infrastructures and communications equipment must evolve to meet this growth.  Maintaining competitive operational costs while increasing the speed, functionality and reach of networks is a challenge.

Innovative cooling strategy results in significant energy savings

A Mexican mobile operator was searching for:

  • An energy saving solution for Legacy end of life Air Conditioners for telecom shelters
  • Emergency cooling in case of power outages
  • Local support and stock

Dantherm recommended Combo Cooling, a total heat management system with 4 operational modes:



1. Free Cooling
2. Air Conditioning
3. Emergency Cooling
4. Heating


Combo Cooling units are designed to replace traditional air conditioners.  They provide huge energy savings by means of efficient, high-capacity free cooling. With this system, you’re able to minimize the use of air conditioning when operating in free cooling mode, which generates significant energy savings.

The Combo unit was tested during the hottest months in Mexico, June – August.  The test results were very impressive:

  • Maintaining an average internal temperature of 27°C, the Combo Cooling unit ran in Free Cooling mode 93% time and in Air Conditioning mode only 7% of the time
  • Achieved energy savings of 89%
  • Achieved total site energy savings of 25%

The Combo Cooling solution resolved the challenges that the mobile operator faced.  The operator will decrease their energy consumption and thereby minimize operating costs, and increase site uptime and improve network reliability with the emergency cooling mode.    Additionally, Dantherm worked closely with the operator to ensure that they were provided with local support to meet their needs.
