Seasonal Ventilation Requirement

Hot and extreme temperatures have proclaimed no remedies but only acceptable for a long time. The heat from the sun’s rays enters the house/shed/industry and heat up the area. 

As a natural phenomenon hot air rises up and in some cases, the temperature in the roof chamber can rise up to 55 to 60 Degree Celsius thereby consequently increasing the temperature inside the house.

During the winter, trapped air inside the building is moist which decreases the life of the roofing sheets, rafters, etc.

To address these problems, it is well-advised to install a Turbine Roof Ventilator to extract air from the roof chambers.

How It Works

  • As a natural phenomenon hot air always rises to the top and if there is no vent in the roof it builds heat at the roof and gradually penetrates down into the house.
  • A turbine ventilator is installed in the roof which operates with the help of wind energy.
  • Turbine blades start to rotate at the slightest breeze/wind (even when the wind speed is 2mph)
  • During rotation, the centrifugal force created draws the risen hot humid air in the turbine towards the spinning vanes and out of the turbine thereby creating a low-pressure area.
  • This low-pressure area is immediately replaced with cool air from below which in-turn is replaced by fresh air from outside through other openings of the building, giving rise to ventilation.
  • Since the turbine rotates continuously the airflow is also continuous resulting in an improved work environment inside the building.
