Clean, fresh air. You’d think it would be something we all have the right to expect in our work places / factory sheds / warehouses and yet so often this isn’t the case. Inadequate ventilation can lead to the build up of heat, moisture and even potentially harmful chemicals in the air that we breathe inside our buildings every day.

SVS offers customers the following unique benefits :

 Engineered long life design as precision bearings have enhanced protection against dust, fumes, smoke, etc.
 All aluminium construction. Only virgin Hindalco aluminium used.
 Higher thickness of material used.
• Wind driven turbo ventilators are always rotating as they start rotating at even low wind speeds of 1 kph.
 Guaranteed no leakage installation as installation teams are SVS owned.
Guaranteed vertical installation of air ventilators on roof sheet by incorporating unique variable angle elbow.
•  Hurricane turbine ventilators are made in technical collaboration with Edmonds, Australia with unique vertical vane design.
•  Hurricane roof ventilators are certified for resistance to rain water leakage and wind loads as per AS2428.1 / AS2050.
 Pan India Installation with presence currently in 23 states of India.
 Regular exporter to many countries
 Experience of large installations of roof extractors.
Largest Range of sizes ( 100mm to 900mm ) and designs (Vertical Vane Ventilator, Spherical Vane Ventilator, Motorised Roof Extractors)


Windy Turbine Ventilators

WINTER
Without ventilation, Moisture laden air rises and condenses in roof space, dampness is trapped.

SUMMER
Without Ventilation heat from the roof space radiates into the room. Heat is Trapped.

INTRODUCING THE HURRICANE TURBINE VENTILATOR

The installation of Hurricane Turbine Roof Ventilators will provide an efficient and cost effective systems 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 l/m at 57.4 km/hr)

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 building.

THE HURRICANE TURBINE VENTILATOR OFFERS

* All aluminium construction

* A varipitch base that suits all roof slopes up to 45

* The Tandaco prepacked double row ball bearing system.

* Vertical vanes for improved starting torque.

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 bearings 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.
They Provide :
• Improved torque at low wind speed.
• Excellent protection against rain.
• Large exhaust opening.
• Positive locking to turbine ring.
• Greater "sail" area to drive the turbine.
