Free Cooling units

Indoor/outdoor free-cooling units designed especially for reliable and cost-effective removal of excess heat in telecom base stations hosting GSM and UMTS networks.

The series of indoor and outdoor free-cooling units is specifically designed to control the internal environment of shelters, cabins or communication enclosures. It is designed to remove excess heat from temperature sensitive electronic equipment where the temperature is required to be maintained within defined limits to achieve optimum performance and to maximize component life.

Free cooling keeps running expenses to a minimum as cooling is provided by fans and ambient air. The products in this series cool without the use of compressors.

Free cooling units

Free cooling units have four standard operation modes (the change between the modes is automatic and follows the temperature).

  • Free cooling
  • Temperature compensation (optional)
  • Shut down
  • Heating (optional)

Free cooling

The Free Cooling units use the ambient air to cool down the room or shelter. In free-cooling mode the external damper will be open and the ambient air will be drawn through the filter by the internal fan and thereby cool the cabin / shelter down. The Free Cooling units are creating an overpressure in the shelter and push the air through the filter and into the cabin. This means that only filtered air enters the room and results in a clean - filtered environment in the cabin. The motorized damper on the opposite side of the cabin will make sure that there will be a low pressuredrop during free cooling.

Temperature compensation

When the outside air temperature falls to an extremely low level, the Free Cooling unit will start temperature compensation. This means that some of the warm air from the cabin will be mixed with the outside air. This is done to ensure that the intake air into the room is not too cold, and to avoid kuldechok to the hot equipment. This function is not standard on all Free Cooling units.

Shut down

When the temperature is below the desired set point the external damper will close to protect the shelter from winds from outside and the fans stop.

Heating

Heating can be necessary in some areas and therefore some of the Free Cooling units are prepared for connection of an external heating element.

The Free Cooling control unit communicates smoothly with third-party software such as overall surveillance systems that manage alarms and warnings from several base stations.
