      Brief Introduction
      FREECOOL-HD intelligent ventilation unit is applied in shelters and small data center. The unit introduces outdoor fresh air with lower temperature to cool equipment room. By using the FREECOOL unit, the running hours of other temperature control units can be highly reduced, achieving power energy saving around 30~90%. The FREECOOL-HD unit using EC fans can adjust the air volume automatically according to the temperature difference with the lowest power consumption.FREECOOL-HD unit with large air volume, high cooling density and luxuriant control functions, can meet all the precision control requirement of temperature and cleanness in equipment room.
      FREECOOL-HD without refrigeration system realizes easy installation and convenient maintenance. The unit is available in 2 different air flow schemes: up flow and down flow, and 2 installation positions: outdoor and indoor, offering more options for different customers.
      Capacity
      2400~21600 m3/h 　
      Applications
      Small to mid-size switching room for telecommunication
      Small to mid-size data center and computer room      		UPS and battery room
      Industrial process control center
      Features
      High energy efficiency
      Using the FREECOOL-HD unit, the running hours of other temperature control units can be highly reduced.


      The main components can be accessed and maintained in front of the unit.


      The unit passed a transportation test to confirm the structure is strong enough to be able to transport on low grade ways.


      The unit framework is provided with corrosion protection treatment.


      Flexible installation types: indoor packaged, indoor split, outdoor packaged, outdoor split.

      		Control to the other temperature control unit
      When the FREECOOL-HD unit can fully meet the cooling demand of base station, the controller can send a signal to stop the other temperature control unit in the site.

       

      Completely auto protection
      The controller monitors the running status of all the components and will stop the running of relative component andraise an alarm if any failure.


      Emergency free cooling
      When power fails, emergency free cooling still operates with 48VDC(only available for DC powered unit)


      Data log
      The controller has a big memory to log the running data of a year.
