Hurricane™ Turbine
The wind driven Hurricane™ Ventilator exhausts hot, stale air from buildings and allows it to be replaced at low level with fresh air at ambient temperature. The result is a much more pleasant and healthier working environment.
How can ventilating be free?
Are you aware of the hidden costs of exhaust fans?
The immediate reaction by many facility owners wanting to improve ventilation
is to add some exhaust fans. Exhaust fans will remove air to be sure,
but when you stop to think about the costs of exhaust fans is it really
an effective approach?
First you have the fan equipment cost, then you have structural modification
costs to handle the heavy weight of the fan; motor starter costs; wiring
costs; electrical operation costs; and finally you have frequent maintenance
costs.
What if we told you that you could ventilate your plant for free!
It's true. Most buildings are creating a natural gravity effect where the hot air is rising from the floor to the roof creating a positive pressure at the upper levels and a negative pressure at the lower levels. Gravity or stack effect is caused by convection (hot air rises), the temperature difference from inside the building as compared to outside of the building and the height of the building. If a proper gravity opening is installed at the roof, the positive pressure caused by stack effect will cause the heat to leave the building. As the heat leaves the building through the roof opening, the air at the floor will be displaced by cooler air entering the building from lower levels.
Why pay for ventilation when Mother Nature will do the work for you!
A properly designed gravity opening will provide ventilation due to stack effect, but by harnessing the wind, ventilation can be improved by 600% or more! Antiquated "doghouse" styled gravity openings are susceptible to wind direction and can actually cause down drafts shutting off exhaust ventilation. With the Hurricane™ wind driven turbine ventilator, the wind strikes the vertical vanes causing the head to rotate. The rotating action generates a powerful area of low pressure causing additional air to be exhausted from the building. Afternoon is typically when the most ventilation is required in a plant. Average afternoon wind velocities in the North America are 6-10 MPH or even higher providing even more FREE ventilation!
