How it works

  • . FCU - (Free Cooling Unit) is equipped with Microprocessor based control unit to precisely control the operation of the Cooling Unit, Air-conditioner and Generator of a Telecom site. Suitable temperature sensors and intelligent interface with the Air conditioning equipment, ensures that this is Switched ON only when absolutely necessary to minimize power consumption.
  • . When the ambient temperature is >2-4 C lower than inside temperature, the heat load inside the shelter is transferred outside through mass transfer between air inside and outside. Free cooling results in reducing the operating time of air conditioner (AC), lengthening the life of AC unit and saving energy.
  • . Specially designed auto operated dampers to restrict outside air contact when not in use.
  • . Specially designed air filters provide clean air, fitted with pressure sensor to generate alarm when filters are choked.
  • . -48V DC operated speed control fans to control the set temperature inside the shelter.
