Wind turbine ventilators

What are Wind Ventilators?Wind turbine ventilators are exactly as the name implies, they are a
                ventilator that is powered by the wind to create effective ventilation for different industries. This
                product works on wind assisted ventilation. Turbine ventilators are round metal vents with fins in them.
                Even just a little bit of wind can be just enough for the turbo ventilator to rotate. The faster the
                wind, the faster the turbine will rotate and exhaust the heat, smoke, fumes, humidity, etc.
The mechanics involved in the air movement is very simple. The hot air inside
                the shed tends to rise up. When the turbines rotate, they suck the warm air out through the vent,
                thereby, bringing out a drop in temperature in the shed and allow supply of fresh air through doors and
                windows.
The size, number and installation all depend on different factors which
                include wind velocity, temperature differential, environment conditions, and the size of the building.
                Turbine vents have been vastly used for many years in residential, agriculture, industrial buildings and
                warehouses.

              
            

              
            

              Roof Top Ventilator advantages:
              Do not need to be powered by electricity.
Are located such that they exhaust the hottest air first.
Do not cause any harm what so ever to the environment.
Tend to save a lot of money.
No operating cost and maintenance free.

            

Seven Rays in Andhra Pradesh to promote Wind ventilation as a concept and use
                a renewable source of energy for ventilation purposes on a large scale commercial use in the Andhra
                Pradesh context.
The concept of wind ventilation was successfully promoted by Seven Rays with
                active patronizing by leading industrial. Seven Rays association with leading Architects and other
                professional involved in Industrial development is mainly responsible for the success of this concept in
                Indian Scenario.
The Seven Rays team sources its raw materials from the finest manufacturers
                and follows strict quality standards. With a dedicated manufacturing facility to produce more than
                10,000 wind ventilators annually, supported with an all-India sales & service network, Seven Rays has
                the ability to engineer & deliver services to suit customers’ requirement at the shortest possible
                lead-times.

How does it work?Seven Rays Ventilators are placed on rooftops of industrial sheds.
Industrial activity generates heat and hot air being lighter moves upwards.
The lighter air get accumulated in the turbine of the Seven Rays Ventilator.
As the hot air tries to escape from the turbine, it exerts a backwards thrust on the vanes and sets
                  them in a rotational movement.
This rotation creates a suction, which pulls more hot air from the room into the turbine.
This rotation creates a suction, which pulls more hot air from the room into the turbine.
With the help of natural wind blowing over the rooftop, the RPM of the turbine increases.
This increases the discharge capacity of the Seven Rays ventilator.
As the hot air is thrown out, fresh air starts entering through windows and door openings.
The Seven Rays Ventilator thus generates continuous air circulation within the room resulting in
                  cooler inside temperatures & discharge of foul smells.
Hygienic work conditions result in improved productivity.
Applications:Factories & workshops:
In factories and workshops, the hot and humid working conditions are induced due to various operations carried out, the numerous motors and machinery installed. Improper ventilation will lead to workmen fatigue and lower levels of productivity. In some cases such conditions of working may lead to labour unrest also. The Seven Rays Wind Ventilator can resolve this issue very easily.
Godowns & warehouses
Godowns and Warehouses require ventilation to avoid deterioration of products stored. Also, there are huge electricity costs associated with conventional ventilators and the there are chances of rodents eating out the electrical wiring. Seven Rays Wind Ventilators function for 365 days a year and 24 hours a day without any problems.
