Heat Exchanger

Heat Exchange

For Telecom cabinets and radio base stations.
The line of Dantherm air-to-air heat exchangers is designed for reliable and energy-efficient temperature control in Telecom cabinets and radio base stations.
Closed loop, energy efficient cabinet cooling
The closed loop, passive cooling systems are perfectly fit for maintaining an internal temperature between 5°C and 15°C above ambient temperature.
Fan speed control and light-weight
Stepless fan speed control ensures that the internal temperature is kept at the exact level necessary to protect and prolong the service life of the electronic equipment in the individual cabinet. A light-weight plastic core ensures an easy, fast and low-cost installation.
Low power consumption
Improved performance, low power consumption and reduced noise emissions make the Dantherm Heat Exchanger a very good choice for small heat loads in cabinets placed both in- and outdoors.
