Bosch Automotive Electronics India manufacturers electronic control units for the motor trade, including spark plugs, starter motors, alternators and generators.

The plant at Naganathapura, in the city of Bengaluru, is one of 18 Bosch manufacturing facilities in India. Each plant is always looking for ways to be more energy efficient.

"We wanted to make our operations greener and more efficient, reducing our energy consumption. We have had a long relationship with Grundfos, so we asked them to audit our cooling system and suggest ways to reduce energy consumption,” said Steevan Fernandes, Deputy Manager at Bosch Automotive India.

As a result of the audit, Bosch began a pilot programme to assess the impact of replacing the cooling pumps with more power-efficient alternatives.

Two Grundfos CRE pumps have now been installed, providing a continuous water supply at a constant pressure.

The energy saving has been considerable. Power consumption is down 47% compared to the old pumps, saving 4.42 kW per hour.

The pilot programme is just the beginning: its success has proved the value of replacing the pumps. More than 100 pumps across multiple Bosch sites will be replaced in 2022.

“The new pumps are helping Bosch achieve its sustainability goals. New pumps will be installed throughout 2022, further reducing our carbon footprint,” said Steevan.
