Capgemini retrofits 1,000 EC fans in India to cut energy use by 30%

Global IT firm Capgemini has implemented large-scale ventilation system retrofits across eight sites in India using EC fans from ebm‑papst, as part of its efforts to reduce energy consumption and meet climate targets.

Since 2016, Capgemini has replaced more than 1,000 outdated fans in cooling towers, air handling units, precision air-conditioning systems, and data centers with high-efficiency EC fans. The installations include 142 Generation 3 AxiBlade axial fans, each delivering airflows up to 40,000 m³/h with efficiency rates of up to 60%, and around 300 RadiCal 2 centrifugal fans with enhanced EC motors and active PFC.

All retrofitted fans are integrated into Capgemini’s Energy Command Center (ECC) via MODBUS interfaces. The ECC enables 24/7 digital monitoring and centralized control, contributing to a measured 30% reduction in energy consumption since the start of the initiative. In 2023 alone, the company consumed 25 GWh less electricity compared to 2019 levels.

“Just as impressive is the technical excellence of the products and the commitment to efficiency, resulting in large savings,” said Viswanathan Rajendran, Vice President of Engineering Services & Sustainability at Capgemini. The company plans to enhance future operations using artificial intelligence in collaboration with ebm‑papst.
