The Physics of Natural Convection in High-Bay Sheds
Industrial sheds with metal roofing act as radiant thermal traps during peak summer months, often reaching internal ambient temperatures 8°C to 12°C higher than outdoor temperatures. Accumulated hot air, fumes, and airborne particulate gather at the ceiling ridge, creating stagnant heat pockets that degrade worker productivity and accelerate roof corrosion.
Zero Power, 24/7 Continuous Exhaust
Unlike powered axial exhaust fans that require high electrical draw and frequent motor maintenance, Greater™ Natural Turbo Ventilators operate entirely on wind velocity and natural thermal convection (the stack effect):
- Stack Effect: Warm, less dense air rises naturally toward the roof apex, creating positive pressure beneath the ventilator base.
- Centrifugal Extraction: As natural ambient breeze strikes the curved aerodynamic vanes, the turbine rotates, creating negative pressure inside that continuously vacuums hot air upward.
- Weatherproof Engineering: Precision hydroformed stainless steel vanes prevent any rainwater ingress while maintaining rotational balance at wind speeds as low as 2.5 km/h.
Economic Payback and ROI
A standard 20,000 sq. ft. industrial warehouse replacing ten 1.5 kW electric roof extractors with twelve Greater™ Turbo Ventilators saves upwards of ₹4,20,000 annually in power bills with zero recurring motor replacement costs.
