Create Envirnomnets for Worker Comfort and Performance.

Uncomfortable conditions in buildings and spaces-too hot or too cold, restrict the ability of workers to function to full capacity and can lead to lowered job satisfaction and increase in illness symptoms. Physical comfort is critical to work effectiveness, satisfaction, and physical and psychological well-being.

It is useful to think of a natural ventilation system as a circuit, giving equal consideration to supply and exhaust. Ventilation techniques using Turbo ventilators can be employed to complete the airflow circuit through a building in addition to door and window openings.

Natural ventilation can be used as an alternative to mechanical ventilation through air-conditioning plants, saving 10%-30% of total energy consumption.

Key BenefitsReduced operating costs - eliminating the power used to mechanically ventilate and cool.
  1. Reduced construction costs - by downsizing or eliminating the cooling equipment.
  2. Reduced building energy use - reducing the environmental impact caused by power generation.
  3. Potentially increased productivity of building occupants - due to real or perceived improvements in the indoor environment.

Energy-saving measures in poultry farms can cut costs by around 20 per cent

The poultry industry is very much driven by costs and efficiency of growth and production, particularly with energy and feed prices being so high. The environment of the stock has a significant impact on this equation and can influence the levels of profitability.
The environments raw materials are as follows: -
  1. Air Quality.
  2. Heat / Temperature.
  3. Moisture Content.
  4. Light.
  5. Food.
  6. Water.
Ventilation is very important in maintaining the correct environment, and directly effects all of the above, particularly in enclosed housing. The main objective being to maintain a natural fresh air condition, at an acceptable temperature to suit the age and type of stock housed.

Poultry compared to other animals have a high rate of respiration as they do not sweat and their only means of reducing body temperature is to breathe more, hence “panting” in hot temperatures. They therefore use up the oxygen available quickly and release large amounts of carbon dioxide, heat and moisture into the air. Poultry are very susceptible to respiratory problems and stale air in the house only heightens these problems, with airborne disease-carrying micro-organisms become more concentrated in stale air.
The key requirements for a ventilation system needs to: -
  • Supply oxygen-laden fresh air.
  • Remove heat released during respiration and activity, and also the solar gain through the structure, particularly in the summer.
  • Remove moisture from the air (released during respiration or evaporating moisture in the droppings).
  • Remove harmful gases (carbon dioxide released during breathing or ammonia evaporating from the droppings).
  • Remove dust particles suspended in the air from the skin of the birds.
  • Dilute disease-causing organisms in the air.
All of above effect the production cycle. If any of the factors above are not being met the birds will either eat more to keep warm or drink more to cool down, will breath faster thereby using up more energy, or “bunch” causing suffocation, or mortality rates will increase due to disease.

Wind e® turbine ventilator resolves most of the ventilation problems by moving air constantly, causing trapped air to be replaced with cleaner, cooler air from outside. They are mounted on roof top and operate without electricity and no maintenece is involved.

Wind Ventilators - Trapped air to be replaced with cleaner cooler air from outside.


Wind e® is a rotary device to pull out hot air in warm months and moist air in cold months. They are commonly located on roof tops, using only wind and pressure differences as their power source. They offer energy savings and comfort with low up-front cost.

Wind e® is incorporated with bearing free German Technology vis-a-via a sealed self lubricating steel device in polymer mounted within the steel shaft, for minimal friction resulting in high RPM and consequent more extraction of hot air. This also results in maintenance free and Silent, Smooth and Sustained operation for more than ten years.
The fan of the ventilator is designed in such a way that extraction of air is more than other fans. The fan blades are made of high grade aluminum, while top cover is Zinc coated steel, and other structure is GI. Powder coated fans are available with lead time for places with corrosive fumes. Due to the nature of its construction Wind e® ventilators can/ are giving trouble free performance for a long time
Wind e® edges are crimped to protect the fan from transit damage and bird hits. Thus at the edges, out fan thickness is 0.8mm. The rest of the vane thickness is deliberately kept at 0.4 mm to reduce weight to get higher RPM, as thicker blades means more weight on rotating mechanism.
Wind e® can be used in commercial, agricultural industrial and residential buildings. These are very affordable, easy to install, and they pump vast amounts of air from workplaces.
So round the year, Wind e® roof turbines can help cut your energy costs; and that means less greenhouse gas emissions and more savings into your pocket!
