The system of air INTRODUCTION with «Settling Chamber» has to assure continuous air exchanges, its main aim is to transfer externally the heat dissipated by the equipment in the radio base stations and data processing centre.

This behaviour is implemented by means of the combined operation of fan and the settling chamber .

  • settling chamber (external) complete with fan;
  • electrical panel “Command and Control” consists of general disconnecting switch breaker, PLC PB13, maximum temperature thermostat ;
  • overpressure

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.

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.

 

Technical Features

  • 48Vdc fan power supply
  • Adjustment of the temperature proportional (0-10V)
  • Very light weight
  • Easy installation
  • Easy access for service and maintenance
  • Low noise levels
