The air extraction system must ensure continuous change of air with the primary objective to transfer the heat generated by the equipment in the dissipation in the radio base stations and local technological generally towards the external environment.

Purposely developed to allow considerable energy saving also in site where were previously installed air conditioning unit without free cooling system.

The system is designed to be managed by its own PLC PB13 to manage the operation cycle and detect the possible causes of alarm conditioning system.

Air extraction system

1 – Group ventilation system (fan, plate, grid) 2 – Overpressure damper with plenum

  • – Electrical panel “Command and Control” consists of general disconnecting switch breaker, PLC PB13, maximum temperature thermostat 

Air introdution system

  • – Air inlet grid with insect protection (A) 5 – Dusty filter

6 – Differential air pressure switch

Adjusting the temperature “ON-OFF” or “proportional” (0-10V). By adopting the regulation “proportional”, they avoid thermal shock conditions when the outside temperature is very low.

This system can also be identified as an emergency system to cool the room as it is provided an electromechanical controller (thermostat) that allows to feed the fan in an independently and separately when the detected temperature exceeds the predetermined values and simultaneously indicates the condition of emergency operation.
