IT company saves energy and costs
Achieving the climate target with EC fans and Energy Command Center
A corporate and technology transformation company in India is relying on sustainable solutions to achieve its climate targets. Two key components play a decisive role here: comprehensive retrofits of ventilation systems with highly efficient EC fans from ebm-papst and central control via the Energy Command Center (ECC).
Since 2016, Capgemini has been pursuing the goal of lowering the energy consumption of its properties and reducing its ecological footprint. In close partnership with ebm-papst, more than 1,000 fans have already been replaced at eight locations in India. The air systems, including air conditioning and HVAC systems, cooling towers and precision air conditioning units for data centers, were previously running with outdated, energy-intensive fans. Significant savings were achieved by using modern EC technology.
AxiBlade and RadiCal 2 for greater energy efficiency
For the cooling towers, 142 ebm-papst AxiBlade axial fans of the latest generation were used, which enable volume flows of up to 40,000 m³/h with an efficiency of up to 60 percent. In addition, almost 300 RadiCal 2 centrifugal fans equipped with an improved EC motor were installed in several identical HVAC systems: they are even quieter and more efficient. These components are easy to install via Plug & Play and have an active PFC to minimize mains interference.
Energy consumption reduced by 30 percent
The results speak for themselves: after the retrofits, Capgemini was able to reduce energy consumption by around 30 percent. Viswanathan Rajendran, Vice President of Engineering Services & Sustainability, emphasizes: "Equally impressive is the technical excellence of the products and the commitment to efficiency, which leads to high savings." In addition to the hardware, Capgemini relies on digital control of the systems. All fans are equipped with MODBUS interfaces and are integrated into the Energy Command Center. This central monitoring system enables automatic, round-the-clock monitoring by specialists. Since the introduction of the ECC, 25 GWh of electricity has been saved at all sites in 2023 compared to 2019.
In the future, Capgemini plans to leverage even more efficiency potential with the help of artificial intelligence. Rajendran explains: "Together with ebm-papst, we want to push the boundaries of innovation and further advance our sustainable goals." With high-tech, data and fresh air, both companies are focusing on a sustainable future.
