DON Wind Ventilator/Wind Turbine Ventilator/Turbo Ventilator |
Don ™ Wind Turbine Ventilator Sustainable Solution for Industrial Units
|
Improving indoor air quality of industrial or commercial space without any recurring expense or electricity is realty now, thanks to the advent of Don™ Wind turbine ventilator. Eco-friendly Don™ vertical vane rooftop turbine ventilator help remove the hot air drafts present inside industrial premises, while also allowing for fresh air to be circulated inside. Also referred to as wind turbine ventilators, they are as their name suggest, ventilators that are powered by the wind to create effective ventilation, catering to the requirements of different industries.
Trapped heat and moisture, apart from raising energy costs can also damage certain structural components of a factory. It is important that an optimum temperature environment is maintained inside factory premises. This is where turbine ventilators come into the picture. With no operating cost involved, turbine ventilators fast finding their way onto the rooftops of several factories.

Some of the advantages of turbine ventilators include:
|
- Cost effective indoor quality improvement solution, since only natural wind is required.
- No need for complicated electrical wiring.
- Light weight and easy to install
- Virtually maintenance free.
- Can also keep rain and dust out
- Helps achieve environmental standards.
- Directly contributes to increased productivity.
- Removes trapped heat and moisture.
- Prevents heat buildup.
- Improves air-conditioning efficiency.

Design Concept: Don™ Rooftop wind turbine ventilator is metal vent that protrude about 20- 30 inches from the roofline. The fins of the turbine are vertical and not spherical. The purpose of the Don™ ventilator is to remove large gusts of hot and polluted air from the factory premises. Modern day technology available in the form of durable lubricated ball bearings is used to rotate the fins. This ensures that even less than 1kmph wind velocity is enough to rotate the turbine. Another major advantage with Don™ turbine ventilators is that hot air which flows up and out of the vent, even when the wind is absent. Additionally, the rotation of the turbine also helps in keeping rain and dust from penetrating inside the factory premises.
Our 24” size Don™ D600 is a vertical vane ventilator is a breakthrough product being manufactured in India. This product has a higher discharge capacity than spherical vane ventilators of the same size along with superior bearing protection as the bearing is placed outside the path of discharge air.
The Tandaco double row heavy duty ball bearings are made from acetal polymer with caged 316 stainless steel precision ground spindle bearings. Acetal is unique polymer that retains the lubricant within its molecular structure to ensure long life and smooth operation. This ensures longer product life and consistent in efficiency over time, which is heart of the Don™ wind mill turbine ventilator.
As the discharge capacity of Vertical Vane Ventilators is higher than Spherical Vane Ventilators of the same size, same amount of ventilation as achieved by spherical vane ventilators can be achieved by 50% qty of vertical vane ventilators. Hence, Ventilation by 100 Nos. Spherical Vane Ventilators can be achieved by 50 Nos. Vertical Vane Ventilators.

Stack Effect: Air inside a building is generally less dense than the air that is present outside. In instances where there is an opening present high on the roof and another opening on the lower part of the building, the natural airflow will cause fresh breeze to enter from the lower opening and exit through the opening present on the roof. This phenomenon is what makes Don ™ turbine ventilator to rotate even in the absence of wind. Once the hot air is driven out of the premises through the opening of the ventilator, a negative air pressure is created inside the factory premises. Cooler air from outside then comes into the building in order to fill the vacuum created by the negative space. Turbine ventilators to maintain an equilibrium condition utilize this constant play of flow of air.

Aerodynamic Performance: Optimum aerodynamic performance is what will ultimately decide the effectiveness of rooftop turbine ventilators. In order to achieve enhanced aerodynamic performance Don ™ turbine ventilators vanes are vertical profiled and rolled. This ensures good vane design and enhanced aerodynamic performance. Lubricated steel bearings are also incorporated as part of the design, for it allows the turbine to spin even in areas where wind speeds are low. Don™ Turbine ventilator achieve rate up to 240 rpm at 16kmph of wind speed, which enables virtually perpetual working of the ventilator. The use of lubricated steel bearings also ensures that absolutely no noise emanates when the ventilator is working.

Ensuring Corrosion Resistance: The rooftop installation of Don ™ turbine ventilator means that they are more often than not, working under extreme weather conditions, which makes corrosion resistance and important issue to be considered. Corrosion resistance is one of the primary reasons why aluminium is used for building Don ™ turbine ventilator. Similarly, the use of aluminium for vanes too helps. The rotation of the vanes helps in repelling rainwater away from the ventilator onto the roof. The vanes are designed in such a way that their rotation creates a centrifugal force that repels water, making Don ™ turbine ventilators perfectly watertight. The fact that Don ™ turbine ventilator is resistant is what makes ideally suited to industrial environs including, pharma plants, power plants, factories, and warehouses, among others.
The size of the Don ™ turbine ventilator and the number of installations depend on factors such as the wind velocity in the particular geographical location, environment conditions, temperature differential, and the size of the factory. Ecospace manufactures turbine ventilator in two sizes i.e 24 “ and 36 “. Apart from the size, a lot of emphasis is also given to the looks of the vent, since they form an important architectural component of a factory building.
