A well designed turbine ventilator, like the Windy, takes advantage of the wind to create a positive flow through the throat of the ventilator.
The wind influences the performance of the ventilator in two ways :
The Windy turbine will even rotate and exhaust in the absence of wind using the thermal currents developed within the building.
Windy Turbine Ventilators promote:
Increase in productivity
Reduction in maintenance of plant & machinery by reducing humidity level
Increased life of roofing sheets
Use of renewable source of wind energy
Achievement of environmental standards
Importance of Ventilator design or placement
As a general rule, hot or stale air will not exhaust through an opening into which wind can blow. Therefore, regular static ventilators, which allow outside wind to enter in the shed because of poor design or location on the roof, cannot be expected to exhaust because they back draft. An efficient means of extracting warm and stale air is through roof mounted turbo ventilators, which create positive draft. Adequate low level provision for the entry of fresh air at ambient temperature should be provided.
Monitor Roof / Jack Roof
Receives no assistance from the wind. Back draft restricts exhaust of air from building.
Poorly designed ridge / gravent ventilator
Does not promote adequate ventilation or air movement in building. Design can allow entry of rain.
Efficient turbine ventilators exhaust hot and stale air and provide a given number of air changes per hour for the building. Does not allow entry of rain.
|Temperature Range||30 To 50 Degree C|
|Throat Size||100mm to 900mm|
The installation of WM cane Turbine Roof Ventilators will provide an efficient and cost effective system of natural ventilation. Designed in Australia for a harsh environment, the Hurricane is suited for industrial, commercial and community buildings. It has also passed the requirements of the Low Speed Dynamic Rain Penetration Test ( 3 Lim at 57.4 kin/hi)
Hurricane Turbine Ventilators improve the working environment:
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, naturally, is a much more pleasant working environment. The Hurricane has other benefits too. It prevents condensation by exhausting moist air. And, in cases of fire, it plays a safety role by exhausting smoke and fumes from the ouilding.
Hurricane Turbine Ventilator offers:
The dynamics of the Hurricane Turbine Ventilator
The unique Tandaco Bearing System:
The Hurricane incorporates the Tandaco double row heavy duty ball bearing system manufactured to perform for a lifetime. It is secured into a reinforced bearing holder with variable length buttresses designed to stabilise the turbine at all wind speeds. The bearing is completely isolated from corrosive environmental conditions by its location between the dome and top diaphragm. The Tandaco bearing is a precision ground spindle bearing with a double row ball bearing cage.
The Hurricane's vertical vanes:
As well as exhausting warm and stale air, ventilators must be weather proof which imposes influences on design that can be detrimental to their performance. Vertical Vane design has distinct benefits over spherical turbines.
