With increasing temperatures, it is absolutely necessary for good ventilation systems. Heat from the sun rays enters the house/shed/shop floor and heats 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?C 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.

Chowdary Enterprises, a division of Chakra Group of Companies, is a pioneer in manufacturing poultry and housing equipment since past three decades. Environmental and climatic control of the houses is very important in poultry and understanding this need the company introduced the roof ventilators to its product portfolio.

These ventilators have been installed on many poultry houses and now the company is introducing them to the open market where these can be installed in various industries - manufacturing, stocking and or warehouse sheds, etc.

The turbine roof ventilators are manufactured with superior quality material on advanced machinery and sold in the market only after securing the approval from experienced quality control department of the company, which assures customers the best quality and longer service life. The ventilators are made of the stainless steel material and are highly resistant to oxidation, corrosion and rust.

Included with the Ventilator is Fibre Reinforced Plastic (FRP) roofing sheet of minimum length of 2 metres. The roofing sheet incorporates a natural water flow slope so that water does not rush back after contacting the dome surface (especially during heavy rains). The roofing sheets can be made to order (subject to a minimum order quantity) to suit to the existing roofing profile. The material of the roofing sheet is selected so that greater strength is achieved in the given thickness.

How the Ventilators Work

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 that operates with the help of wind energy. Turbine blades start to rotate at the slightest breeze/wind. 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 opening of the building, giving rise to ventilation.

Advantages

• Enhances the life of the insulation, roofing sheet, rafters, etc., by removing accumulated hot, humid and polluted air
