Global Air Crisis
Design Development and CFD
VERTO has been designed using the principles of aerodynamics, to create a form that propagates maximum surface area and increased wind speed for a robust and efficient performance. Simulation studies were conducted to attain minimum resistance and maximum surface area to achieve this optimum design. An elliptical geometry has been designed as the starting point, as this gave us the minimum resistance. The form was further developed by twisting the form; this twist in geometry channels the wind along the surface of the tower in the Z direction, thereby exponentially increasing the surface area.
The rotation of the tower was further developed using CFD analysis to ensure that clean air is not getting mixed with unfiltered air being sucked at various levels. A part of the CFD analysis was to ensure a 360-degree purification zone and maximum output of clean air.
The design of the tower consists of a triangulated component, to ensure ease of execution. Each component is tapered in to create a compression of wind and thereby further increasing the air being pushed in. The perforation pattern is designed as a performance driven system with bigger openings at inlet and outlet areas. This gradient of openings also gives the design a stark helical move accentuated by the perforation pattern.
Air Purification Capability
VERTO can clean about 600,000 cubic meters of air per day, which is equivalent to an area twice the size of a cricket field with a height of 2 meters. The filtration tower is equipped with energy-efficient fans that suck in the ambient air which then get filtered using fine dust filters to remove the pollutants from the ambient air including the fine dust particles (PM2.5, PM10). An IoT control system enables the operation according to the demand.
The name VERTO is derived from the word “turn”. The tower rotates as it rises and transforms the environment by turning polluted air into clean air. The first VERTO was inaugurated on 26th August 2022 at Sunder Nursery Park, New Delhi, by Dr Philip Ackermann - German Ambassador to India & Bhutan.
Variable Speed and IoT
A control system enables the operation of the filter columns to be adjusted according to demand and thus react to the current air quality. External sensors record air and weather data, which are collected and evaluated in cloud. This technology has been available since 2018 and has been successfully implemented by German governmental institutions to tackle pollution levels in some of the most polluted traffic segments in rural areas to maintain the strict EU pollution levels.
Modular and Plug & Play
Based on plug and play design, VERTO can be shipped in a flat pack state and assembled on site with ease due to the modular design. Use of GRC panels ensure a long lasting and sustainable product.
